Amber Meyer was the South African Institute of Industrial Engineering’s Best Final Year NDip student in 2019, yet she never thought she would graduate, twice in a row or cum laude, having had to overcome educational and financial hurdles.

This year she is graduating with her BTech in Industrial Engineering also cum laude at the Autumn Graduation. "I cannot believe it".

The first two graduates in BEngTech Marine Engineering graduated at Nelson Mandela University’s Autumn Graduation.

Matthew Nel and Aidan August are furthering their studies and have enrolled for the 4th year honours in Mechanical Engineering at the University, taking selective specialist modules in marine engineering focusing on ship and marine craft design.

 

 

An Autonomous Solar Boat prototype that was designed in Nelson Mandela Bay will soon have its maiden voyage at sea.

The boat is a pilot project of the South African International Maritime Institute (SAIMI)-funded Marine Robotics Centre based at Nelson Mandela University. SAIMI promotes these and other innovative projects to increase technological advancements in the maritime sector through the support of the National Skills Fund (NSF).

 

 

In this professorial inaugural lecture Professor of Mechanical Engineering at Mandela University, Russell Phillips, unpacked the role of renewable energy in de-urbanising post-COVID Africa.

In his lecture, delivered virtually on 28 June 2021, Prof Phillips spoke of how the world is becoming increasingly urbanised with more than half of its population living in cities.

Nelson Mandela University has opened up a second vaccination site, specifically dedicated to its 29 000 students.

Collaboration between the sciences and the social sciences can only lead to the improvement of sustainable and renewable energy, the effects of climate change on the environment, food security and the alleviation of poverty. 
 
In this case, engineers as scientists are solving technical challenges contributing to social benefits.
 
This message was shared at the webinar Conversation 3: The Sciences in Service of Society hosted by Nelson Mandela University’s Engagement and Transformation Portfolio – Hubs of Convergence.  The School of Engineering’s Professor Russell Phillips, Karl du Preez and lab intern Kabelo Mpurwana as well as guesthouse owner at Riemvasmaak, Elisa Namases, were the presenters.  
 
Riemvasmaak in the Northern Cape is about 20 km east of the Namibian border and has the highest solar energy in the country with temperatures reaching 50 degrees Celsius in summer.  The arid desert landscape receives less than 50mm of rainfall annually.  
 
This is where, for a number of years, Mandela University’s School of Engineering has performed solar and wind energy research, benefiting a small farm, a guesthouse and the community, as well as many students who not only learnt by doing the practical work but also realised their value to the community. 
 
The project started with Prof Phillips’s passion for de-urbanisation as a solution to not only the effects of climate change, but also alleviating poverty. “I firmly believe that people should live outside the cities, de-urbanise and for that, they need energy, connectivity and effective ways to run small farms.  This means spending time with communities to find out what their needs are and discuss the best possible solutions with short term initiatives.  We take our knowledge for granted, but how do we as engineers contribute to job creation and agriculture as a business, which is at the forefront of this project?” he says.
 
The Riemvasmaak project is run by the School of Engineering’s Advanced Mechatronic Technology Centre (AMTC) and is funded by merSETA (the Manufacturing, Engineering and Related Services SETA).  The AMTC has been in existence for the past 18 years and is currently involved with drone projects and short courses, the marine engineering degree and the Stem in Action schools science project, among others.
 
Initially, the Namases family used a petrol pump to get water from the river for household use on their family farm and often had to carry the water a long distance.  From there, the idea was born to run a solar pump to save them money and to have a sustainable energy source.  
 
Since the first project -  setting up a solar pump - the farm has grown to boast a viable guesthouse and an extensive vegetable garden, from melons to beetroot and carrots, which not only supplies the Namases family, but also the elderly nearby.  
 
In 2020, the first live research site was established on the farm, feeding research data to the University and the guesthouse. Owner Ms Elisa Namases, who grew up on the farm, signed a formal Memorandum of Understanding with the University.  A second set of solar panels was installed as well as two wind turbines to assist in supplying electricity to the guesthouse and to pump water.  
 
“They know the best solutions and we can listen to them.  I am, for example, working on a kit for a solar pump for communities to build their own water pump.  We as engineers, have to venture out of our silos to solve pressing societal issues and add value.  My greatest takeaway from this, my biggest project, is the satisfaction of building something that changes someone’s life.  Although the extreme heat was challenging, it was satisfying to see an idea become a reality.  We can start at home with small projects making a big difference, Kabelo said.
 
“I will never forget our emotions when the first water was pumped out of the river.  This research project also grows our students.  The project demanded hard physical labour for days, which we as staff and students performed together both in our labs and on site.  Kabelo worked through lockdown on this project,” said Mr Du Preez. 
 
“It is difficult to involve academics in these projects as we all have a fulltime workload as lecturers and projects need funding.  One has to build on your relationship with funders, then funding is more easily available for sustainable projects.  In this case, it is a viable system which has been running for a number of years.   
 
Hubs of Convergence’s Dr Bruce Damons mentioned the advantage of tapping into Ms Namases’ indigenous knowledge, shown on a short video. For example, she knows exactly what will grow in the arid conditions, yet fertile soil. The knowledge exchange for researchers and students is extremely valuable and similar projects should also be looked for in the Eastern Cape.
 
Dr Ossie Franks from the Strategic Resource Mobilisation and Advancement Office, encouraged suggestions for the future including to involve other departments, for example, the University’s Agriculture department to assist the farm and expose students to the environment.
 
Prof Phillips mentioned a doctoral project in the Engineering School, also working on a solar-powered agricultural vehicle doing weeding, picking and other functions on a small-scale farm. 
 
More people should be informed of the reciprocal benefits for society, staff and students that research can play and the University’s Hubs of Convergence emphasise this work in service of society.  The importance of knowledge sharing and application through various mediums was also emphasised to extend the impact of the engagement and research, and to further sow seeds for further inter and transdisciplinary collaboration with multiple communities (stakeholders).
 
Engineering students and academics from Nelson Mandela University and the University of KwaZulu-Natal (UKZN) represented South Africa in the 2020 Global Cybathlon Championship hosted by Switzerland last weekend. 
 
The Team, with the support of the Robotics Association of South Africa, were the only participants selected from Africa.
 
The Cybathlon is a unique, international multisport event with 60 teams from 20 countries taking part. The championship in which people with physical disabilities compete against each other to complete everyday tasks using state-‚Äčof-the-art technical assistance systems is beyond just a competition – it also offers a platform to advance research in the field of assistive technology and to promote dialogue with the public about the inclusion of people with disabilities in everyday life.
 
Our Touch Hand team finished 11th out of 13 international competitors in their section, which featured mainly research and private sector entries. Sadly, a faulty tin can opener, supplied by the organisers deprived them of ending in the top 9. "Anything above that would have been beyond their reach with their current iteration as a massive funding injection as well as years of experience would be required" said Clive Hands from the Advanced Engineering Design Group (AEDG) in Mandela University’s School of Engineering.
 
The team finished above both the UK and Germany and the media attention gained was extremely encouraging. “Our students did us proud” said Clive.
The Damas guesthouse in the remote Riemvasmaak area in the Northern Cape, which received its first off-grid facility from Nelson Mandela University two years ago, now boasts a larger pumping system as well as an off-grid power supply system for lighting.
 
The first 1kW portable solar pumping station, developed by the University’s Renewable Energy Research Group (RERG), in collaboration with the merSETA (Manufacturing, Engineering, and Related Services Sector Education and Training), was designed to supply the guesthouse as well as Elisa Namases’ home with enough water for domestic use, which included the irrigation of two small vegetable gardens.
 
According to RERG’s Prof Russell Phillips, the pumping station was fitted with a remote telemetry system which allowed the University’s researchers to monitor its performance.
 
“This pumping station is responsible for much of the greenery around the guesthouse as well as maintaining the vegetable gardens, which are a primary source of food for Ms Namases, her extended family, and many of the elderly in the surrounding local community.
 
“Prior to the installation of the first pumping station in 2018, the family physically carried water from the river for their needs.  Based on the success of the initial pumping installation, the University’s Advanced Mechatronic Technology Centre sought funding from MerSeta for a larger system.  This was approved and the installation was completed by the University team in the latter part of September 2020“.
 
The maximum energy demand for lighting for the guesthouse was calculated to be 1.26 kWh per day.  To meet this demand, a 1kWp PV solar array was installed to charge two 100 Ah deep cycle batteries.  To supplement the solar array in charging the batteries, two wind turbines were added.  An off-the-shelf horizontal axis wind turbine (HAWT), the ReGen 400W, and an Mandela University RERG designed custom-built helical savonius vertical axis wind turbine (VAWT) turning a 500W Ginlong generator.
 
“While the area has a low annual average wind speed, it was noted that particularly in summer, the region experienced brief, strong nocturnal winds that are expected to supplement battery charging significantly and ensure 24/7 availability of lighting for the Namases’ household and guest house.”
 
Prof Phillips says the primary aim of this project was to provide off-grid power for pumping and lighting to the Damas Guesthouse and a high DNI research test site for the University via a mutually beneficial formal agreement between the family and the University.
 
According to him, there are numerous secondary spin-off benefits.  These include adequate energy and water to allow the family to be self-sufficient, improved quality of life for the family, a research test site for the University with low-cost overheads as well as the transfer of technical and farming skills to the local community with a view to additional similar projects in the region.
 
As part of the ongoing project, a second research site is located in the Riemvasmaak area earmarked for the solar pump array as well as future Mandela University research projects.  The site is roughly 150m from the river, while the hectare of land to be irrigated is approximately 370m from the river.
 
Phillips says for the University, the next phase of this project is to enclose Research Site 2 which will be used as a storage facility for future projects.
 
“A communication link between our North Campus in Port Elizabeth and Research Site 2 will also be installed to monitor and receive live data from tests being conducted.”
 
Reasons to be Proud - #R2bP: In a first of its kind, the biennial international BRICS* Skills Challenge 2020 took place in a virtual online format, and Mandela University student Jacques Welgemoed (23) was part of the experience.
 
The master’s in Mechatronics student Welgemoed, mentored by Damian Mooney, represented South Africa in the challenge and achieved joint second place with the Temasek Polytechnic of Singapore taking top honours.
 
This year, 85 participants from 12 countries took part in a seven-day Drone Operating camp and challenge hosted by Copter Ex of Moscow, Russia.
 
Welgemoed became a volunteer intern with the Mandela University Autonomous Operations (MAO) group in early 2019 showing a strong aptitude for software coding and drone development. He was selected to represent the University and South Africa at the WorldSkills challenge in Kazan, Russia in 2019 where he placed 3rd place behind Russia and China.
 
“Ideally a new student would have had the opportunity to represent South Africa this year but with limited training time due to COVID, it was decided to give Jacques the opportunity to compete again, this time achieving silver,” says Mooney.
 
One discipline, in particular drone operating, has surpassed all expectations by not only hosting an online teaching camp but by implementing the actual challenge event and assessing competitors throughout the world simultaneously.
 
Welgemoed describes the Skills Challenge as fun and a great introduction to autonomous micro aerial vehicles.
 
“It was interesting to be able to write a programme at home and fly a drone with that programme in a different country. It provided valuable experience working with software relevant to my research topic and the instructors provided helpful feedback and advice with regards to this.
 
The participants were taught the finer points of drone programming and autonomous indoor navigation in an online classroom before being tutored individually by CoEx personnel to bring all participants up to a similar level of competency.
 
Over the course of four days, the competitors were tasked with writing code that was then uploaded to physical drones waiting in a warehouse in Russia that would then perform the tasked flights. Competitors were presented with surreal live YouTube footage of their drones, essentially on the other side of the world, flying autonomously using the code they had just written.
 
The drones needed to navigate to specific positions in the testing warehouse without GPS relying solely on visual cues and then perform measurements on the dimensions of boxes placed at those positions using laser range finders.
 
Mooney is proud of Welgemoed’s repeated achievements as a member of the MAO. “It is an indication to us that both parties are of a world-class standard. Jacques’ ability to blend a professional approach to the very demanding challenges whilst maintaining a visibly positive disposition of helpfulness and camaraderie instils a sense of patriotic pride having him as an ambassador for South Africa. The Mechatronic Engineering training Jacques has received through Nelson Mandela University has proven to be not only relevant but of a standard that is noticeably competitive with the rest of the world,” he adds.

The first four intubation units designed by Nelson Mandela University’s Advanced Engineering Design Group (AEDG) were recently delivered to the Anaesthesiology staff at Livingstone Hospital.  
 
In response to the COVID-19 pandemic and the strain being placed on our local hospitals, lead PE Hospital Group Anaesthesiologist for COVID-19 response, Dr Lorenzo Boretti, earlier this year, requested the University’s AEDG students to design an intubation unit for the local PE Hospital Group.   
 
Director of eNtsa (the Innovation through Engineering Institute housed at Nelson Mandela University) Prof Danie Hattingh managed to secure funding from the MBDA (Mandela Bay Development Agency) to build the Intubation Units so that several could be supplied across the PE Hospital Group.  
 
In addition, Nelson Mandela University alumnus Cecil Frost, director of Shibah Engineering, organised the manufacturing of the intubation units.   
 
The intubation units encompass the intubation box, including the vacuum extraction units and custom-made connections and adaptors for quick installation, set-up and use in theatre scenarios.  They have been tested in in-theatre training sessions for their effectiveness.
 
After some delay with administrative issues, the first units have been delivered as an additional layer of protection for our healthcare professionals, says Clive Hands, the project manager from AEDG.
 
National funding is now being sought so these can be deployed to hospitals across the country to further assist in the fight against the pandemic, says Mr Hands.
 
For more information about the development of the intubation units including the trials and tribulations encountered along the way see the AEDG website: https://aedg.mandela.ac.za/Projects/Intubation-Unit-Accesories
 
Short lessons, recorded experiments, career exploration and wellness segments, are just a few of the interventions planned by Mandela University’s STEM IN ACTION’s programme to assist Grade 12 learners once they are back at school.
 
In 2019, some 2700 learners and their educators from 37 schools in Nelson Mandela Bay, benefited from this science and mathematics programme. 
 
Several learners, especially Grade 12s, are currently facing anxiety, concern about the curriculum coverage and a shortage of data for online lessons, as a result of the country’s national lockdown to curb the spread of the Coronavirus.
 
These STEM IN ACTION’s interventions can assist with curriculum coverage and uncertainty about the future.
 
Isabel van Gend, STEM IN ACTION project manager, says their strategy is to support the educators with interactions that they identify and to support the learners by working together with them. 
 
This includes hosting an online community of practice session once a week for all interested Physical Science educators.  During these sessions, ideas and tips will be shared, not only about the teaching and learning of Physical Science but also how to best navigate and support learners in these challenging times.
 
However, it all depends on what the Department of Basic Education’s curriculum plans are when the school year resumes.
 
“There are talks of cutting certain content.  We can only put definite plans in place when these parameters have been set.  We are ready to assist online, but do not want to waste our time or the learners’ by assisting with content that is not relevant,” says Isabel.
 
The STEM IN ACTION programme, which runs from the University’s Missionvale Campus offers several Science projects.  One of which assists and support 290 Grade 10 to 12 learners from 20 schools in curriculum-enhanced Physical Science interactions during four afternoons per week.
 
In addition, the programme supports 30 disadvantaged schools, including Khumbulani High School, Khwezi Lomso Comprehensive School and Morningside High School, to improve their chances of success, including experiencing real-life physical science experiments in their laboratories on the Missionvale Campus.
 
All interactions are aimed at improving National Senior Certificate results, increasing the number of learners choosing Physical Science as a subject and to inspire learners to follow careers in Science and Engineering.
 
The programme also includes exposure to study methods and skills and career exploration opportunities for several of the projects under the STEM in ACTION umbrella.
 
The University’s School of Engineering partnered with the South African National Roads Agency Limited (SANRAL) in 2010 to start the STEM IN ACTION programme which aims to equip learners with the necessary skills to enter the Science, Technology and Engineering (STEM) fields.  To date, more than 17 000 learners have participated in the programme.
 
The programme was started due to the decline in the number of students qualifying for courses enabling them to become professional engineers.
 
Isabel says many learners have been disadvantaged in trying to achieve the entry requirements for diploma and degree programmes in science and engineering due to various factors. These include socio-economic factors, a poor foundation in mathematics, lack of stimulation and an interest in science in primary school, exposure to inadequate teaching and learning practices as well as the scarcity of subject-specific educators in mathematics and physical science in the General Education and Training (GET) and Further and Education (FET) phases at school.
 
One of these successful learners is Arshad Chengadu, a former learner of Morningside High School, who obtained 96% for physics last year and who is currently a first-year student studying towards a degree in mechatronics at Nelson Mandela University.
 
“The programme covers broad topics; not only physics and mathematics.  It has taught me the importance of teamwork and has assisted me in choosing the course I’m currently following.
 
“Overall my marks have remained constant.  This would not have been possible without the programme’s unique teaching methods to assist learners in understanding instead of memorising.”
 
Another former STEM IN ACTION participant is Nomalungisa Norawana who works in the transmission department at Vodacom in Limpopo.
 
She attended Khwezi Lomso Comprehensive School and was part of the programme from Grade 10 to matric.
 
“The programme assisted me in understanding science better and I was able to assist others from my school.
 
“My marks continued to improve each term.  My final mark for science in matric was 82% and 87% for maths.”

Reasons to be Proud - #R2bP: Professor Danie Hattingh, Director of eNtsa (the Innovation through Engineering Institute housed at the University) and Professor in Mechanical Engineering, has been announced as one of 2020’s Suid-Afrikaanse Akademie vir Wetenskap en Kuns (SA Academy for Science & Art) prestigious Award winners, namely the Honorary Medal of the Faculty of Natural Science & Technology.
 
Prof Hattingh is honoured for his contribution in the field of friction welding and the associated development of the analysis of metal turbines and high pressure/high-temperature pipes.  These techniques are currently being used as standard procedures at both Eskom and Sasol.  The technological contribution of Prof Hattingh and the eNtsa Group is crucial to Eskom's continued supply of electricity in South Africa.
 
This Honorary Award for achievements and contributions in the promotion and development of this particular field of study, is only awarded in exceptional cases.  The awards will be handed over at a future date.
 
Prof Hattingh became the Director of eNtsa in 2009. The Institute has an annual turnover of some R50m generated from industrial and government contracts for assistance with research, design, or process development.
 
Over the past ten years, Prof Hattingh and his team of researchers have won various national awards and international acknowledgement for their ground-breaking research and applications conducted within the friction processing arena.  This medal is the latest recognition of the important work done by Prof Hattingh and his team.
 
In 2001, Prof Danie Hattingh was a visiting researcher to the School of Marine, Manufacturing and Mechanical Engineering, at the University of Plymouth, United Kingdom, where he participated in a research project on Friction Stir Welding and Residual Stress Measurement using Synchrotron Radiation. 
 
This research led to the establishment of eNtsa (Centre for Innovation through Engineering) at the then PE Technikon, now Nelson Mandela University.  The name ‘eNtsa’ is derived from the isiXhosa word ’eNtsha’ meaning “new”.
 
In the mid-2000s, Prof Hattingh and his team were involved with research and development work in aid of high-value large-scale engineering projects, most notably with Eskom to develop alternative materials’ sampling and weld repair techniques for its ageing steam boiler fleet. 
 
At the heart of this development was the now patented WeldCore® sample extraction and repair technique.  WeldCore® is a novel sample and repair technique that involves in situ material sampling of, for example, high-pressure steam lines.  This process consists of extracting a cylindrical sample and removing it from the pipe wall. 
 
The extracted sample is then used in a series of tests to establish the extent of the accumulated creep damage and the remaining creep life of the metal of the pipe.  The tests include X-ray tomography, to reveal void-like defects, as well as punch testing for yield and tensile strengths; micro-Vickers hardness; and for wet chemical analysis. 
 
This extraction leaves a blind-hole in the pipe, with the inner wall still intact.  The hole is then repaired using a tapered friction pillar process using the solid-state friction welding technique.  The sample cutting and the repair equipment are mounted onto the same machining frame enabling sampling and repair to proceed as sequential processes. 
 
 
In doing its part to combat Covid-19, Nelson Mandela University has already donated more than 100 3D-printed visors to Livingstone Hospital.
 
The university’s recently established Covid-19 co-ordinating committee was working on the printing of face shields and through the engineering subcommittee made a batch of 140 shields delivered to Livingstone on April 4.
 
NMU vice-chancellor Prof Sibongile Muthwa said the university had donated a further 60 shields to organisations in the private sector. (This is in fact incorrect - face shields were only donated to the  Port Elizabeth Hospital complex - web editor). 
 
“The estimated need for face shields in the province is at 4,000. The university has increased printing capacity from 10 to 100 shields a day, which will go a long way in speedily meeting the order of 600 units for Livingstone Hospital,” Muthwa said.
 
On Tuesday night, health minister Zweli Mkhize announced the cases in the country had risen to 1,749.
 
Registered cases in the Eastern Cape were at 32.
 
InnoVenton, the university’s Institute for Chemical Technology, produced its first batch of 200l  of sanitiser within two working days nearly three weeks ago and was looking at ways to upscale production.
 
Muthwa said that, in response to the provincial government calling on all stakeholders in the province to play their part, the university had dedicated itself to contributing towards provincial efforts in line with its commitment of being an institution in the service of society.
 
“Among the more immediate needs are face masks and alcohol-based sanitiser, which the university has been producing.
 
“About 250l  of sanitiser and 400 disposable masks were donated to the provincial government during a visit by premier Oscar Mabuyane and health MEC Sindiswa Gomba on April 2.
 
“Since the establishment of the CCC on March 31, great progress has been made in developing a memorandum of understanding with the office of the premier and in responding to immediate needs through the various subcommittees,” Muthwa said.

Seeing the need for devices to assist people suffering from Covid-19 and other diseases, a multi-disciplinary team of innovative young engineers based at the Propella Business Incubator in Port Elizabeth have dropped all their other projects to develop a low-cost bag mask ventilator.
 
The device fills the urgent need for a low-cost non-invasive ventilator for less serious cases, and frees the expensive units used in intensive care units for those in need of advanced care.
 
“I was impressed by the simplicity, yet effectivity of the design,” says Port Elizabeth anaesthetist specialist Dr Hennie Smit.
 
“It is meant to assist respiration and not full ventilation, and therefore only needs a tight-fitting face mask, and is suitable for use in general wards where it can be monitored by non-specialist nurses,” he said after evaluating the working prototype.
 
Propella incubator members and Nelson Mandela University engineering students Zain Imran and Neo Mabunda teamed up with Zain’s brother Zaahid and Kelvin Langwani to develop a working prototype within five days.
 
“In anticipation of the lockdown we moved our 3D printer and other necessary equipment and components such as motor and microcontroller from Propella to Zain’s home,” says Mabunda.
 
The team, which has complementary engineering skills, is now back at the Propella Business Incubator, with special permission.
 
At the heart of the unit is an inexpensive plastic pouch called a bag-valve resuscitator, or Ambu bag, which most hospitals already keep and, crucially, according to Zain Imran, already has the necessary medical certification.
 
“We set the standards based on WHO (World Health Organisation) requirements for ventilators and ticked all the boxes, such as the volume of air delivered to the lungs, the breaths per minute, Inspiration/Expiration Ratio (IE) and control/fail-safe capabilities,” says Imran.
 
“The result is a pre-intensive care ventilator that ticks many of the requirements of a high-end ventilator.”
 
The Salutaris (Latin for life-saving) device is powered by a servo motor that expands and contracts two arms. Rapid prototyping was possible thanks to the 3D printer.
 
It can be powered by mains or a car battery and durability testing is underway.
 
The Propella team is also linked to the Massachusetts Institute of Technology (MIT) in the US, which is working on a similar concept.
 
“A number of teams around the world have announced ventilators which appear to be functional, but where the Salutaris differs is that it is a highly engineered solution designed from the outset for manufacture with full production and cost optimisation in mind,” says Engeli Enterprise Development operations director Wayne Oosthuizen.
 
Engeli, which founded the Propella incubator together with NMU, is assisting with fundraising and commercialisation of the bag ventilator to ensure it is made available to hospitals and clinics as soon as possible.
 
“We are aiming to start production as soon as the tooling for the injection moulded parts is complete. All that is holding us back is the finalisation of the funding needed for the tooling and initial investment in components,” says Oosthuizen.
 
Another Propella member, Clifford Hamilton, is working on the moulds and helping with the design to make it as efficient as possible for manufacturing.
 
Final pricing is not yet available as some components will have to be imported, “but we are setting our pricing benchmark at R5,000 or less.
 
“This isn’t about maximising profits, but getting an operational and cost-effective ventilator into hospitals,” says Oosthuizen.
 
A production facility is being designed with the help of Grant Minnie of Propella, who is an industrial engineer.
 
“We have the factory space and are sourcing certified reusable face masks, which will both bring down the operating costs of the machines and speed up delivery.
 
“The plan is to produce up to 20,000 units a month, if the market demands this,” he says.
 
“This fast-track rollout from concept to production shows the power of the Propella ecosystem which we have crafted over the past few years,” says Propella manager Anita Palmer.

With the Covid-19 pandemic hitting South Africa and starting to take root in the Eastern Cape, medical staff at the local Livingstone Hospital are under enormous strain.
 
The Advanced Engineering Design Group (AEDG) at Nelson Mandela University received an urgent appeal from anaesthetist Dr Lorenzo Boretti through orthopaedic surgeon Dr Bryan Theunissen, regarding challenges faced by the in-theatre anaesthesia teams in their Covid theatre. In an effort to assist, the AEDG put together a project aimed at helping to protect healthcare workers at the frontline who rely heavily on Personal Protective Equipment (PPE).
 
The challenge is to contain aerosolised droplets from patients with possible Covid-19 virus infection during procedures to ensure that the theatre staff assisting in the operation are minimally exposed to these droplets.
 
The AEDG team as well as multiple contributors from their network of both academic and private sector experts, immediately started an online process of working on a possible solution to the challenge.
 
Initial information was difficult to come by as the medical staff at Livingstone are constantly on call dealing with the crisis, so a basic set-up was ultimately agreed upon as a starting point which could be updated as more information came to hand. An initial conceptual idea was sent through by Dr Theunissen.
 
This work-in-progress is being updated continually and the team are now at a point where their initial design has gone into its 3rd version, with the previous version tested in-theatre last week. There has been some interest shown from hospitals in East London and Kwa Zulu-Natal via their network of contacts and it is anticipated that there will be further expansion.
 
This team effort is an excellent University collaboration example with the AEDG Team (Clive Hands, Dr William Rall, Zaahid Imran, Jode Fourie, Daniel Trask, Sthuthi Varghese, Blessed Tembo, Charl Rossouw and  Zain Imran) working with colleagues from eNtSA (Prof Danie Hattingh, Riaan Opperman, Riaan Brown), the Faculty of Engineering; the Built Environment and Technology as a whole (Prof Ben van Wyk, Gideon Gouws, Prof Farouk Smith, Dr Anne Lourens, Prof Hannalie Lombard, Mervin Knoesen and Amish Lalla), the University’s Medical School (Philipp Hoelzer and Dr Elizabeth du Toit) and Innoventon’s Dr Shawn Gouws.

Gorlach said it is important to expose Mechatronics students to the real industrial world, so that they can be better prepared for the final-year project.

 

On Friday, 24 August, the Mechatronics students assembled for an event that was unprecedented in the department – a Mechatronics Soccer Day. The goal of the event was to encourage team-work, and to form social connections between all members of the department.

Our Eco-Car Team were again crowned Champions of the 2018 Shell Eco-Marathon: South Africa (SEM: SA) in their category this last weekend in blisteringly hot conditions at the Zwartkops Raceway in Mid-Rand, Gauteng. This year’s event saw a record entry of 21 competitors from 4 different African countries, including International University entrants from Nigeria, Botswana and Namibia.

Mechanical Engineering student, Wian van Aswegen from Port Alfred, has designed and created a unique 3D metal printed golf putter.

Wian is a former youth national and provincial golf champion and a member of the Advanced Engineering Design Group (AEDG) in the School of Engineering at Mandela University. In the middle of 2020, he discussed the possibility of designing a bespoke and re-configurable golf putter that he could use in the various golf tournaments with his lecturer, Clive Hands who runs the AEDG.

This would involve the use of metal 3D printing and composites. This was done hand-in-hand with the AEDG’s established relationships with Rapid3D and Custom Works who contributed towards the ultimate physical outcome. The idea was to create a putter that could conform to a golfer’s specific desires in respect of the configuration of the club, be it weight, weight distribution, styling, balance, loft and material.

Wian tackled the design of the club in addition to his academic loading, and was able to produce a prototype that could be manufactured and physically tested out on the greens. This prototype was tested this last Saturday for the first time on the greens at the Royal Port Alfred Golf Club, with excellent results. “We are very proud of how the club came out and it has already attracted envious attention within the local golfing fraternity” said Clive.

The next step in the development of the club is to further test it and further enhance the design with the ultimate intention of registering the club with the Royal & Ancient Golf Club at St Andrews in Scotland (the curators of the rules and regulations of the game) for use in formal competition.

According to Clive, “It is one of the very few 3D metal printed golf putters with forged carbon composite inserts in the world, and, to our knowledge, probably the only current locally manufactured golf club, which is normally left up to the international big players like Calloway, Ping, etc.”
