Year 8 pupil Keon Robert has won an international 3D design challenge with his idea for a solar-powered bulldozer with special caterpillar tracks based on those used on Moon rovers.

Judges in the Polar Cloud CAT Inc. Design Challenge congratulated him for combining creativity with practicality in his design, and he also won appreciation from other users of American manufacturer Polar 3D’s Polar Cloud online 3D design platform.

To maximise his chances in the competition, which was sponsored by heavy plant manufacturer Caterpillar, Keon even produced an alternative design for the other type of caterpillar – the larval-stage insect – in its natural setting, as well as later producing a design based on snowflakes.

Keon’s victory in the heavy machinery category of the competition won a Polar Cloud-enabled Polar 3D printer and $100 for Queen Elizabeth’s School.

QE Head of Technology Michael Noonan said: “Keon’s achievement is a truly remarkable one. He promoted and shared his idea widely, and his was an outstanding example of design and creativity. He received plaudits from Polar 3D’s CEO, Gregory Lalonde, and many others within the Polar Cloud platform, one which has over half a million members.”

Keon explained his thinking and the process by which he arrived at the bulldozer design.

“I decided to reimagine and reengineer your typical bulldozer by adding features which allow for greater accessibility to remote areas, as well as providing a greener alternative to the standard vehicles.

“Firstly, at the back, there is a retractable claw which is able to lift five tonnes. This was created as a feature to utilise when carrying more rubble or dirt. The treads for the vehicle are intended to be made out of wire mesh and rubber to ensure balance and protection, which is a necessity for users who require some means of transportation in more secluded regions.”

This combination of materials was, in fact, used by the vehicles taken on the Moon landing missions, and is, therefore, ideally suited to rocky environments, Keon explained in his design notes.

“Furthermore, photovoltaic cells were added in order to absorb the sun’s solar energy. This would then be converted to electrical energy to power the vehicle via a generator in the engine compartment. The engine compartment also includes lithium-ion batteries, as another energy source in the event of a breakdown.

“Finally, like any other bulldozer, there is another digger at the front, which can carry lift around 35 tonnes.”

Judges stipulated that entries should not only fulfil criteria such as printability, design execution and creativity, but also prioritised those, such as Keon’s, which garnered higher numbers of ‘likes’ on the online platform.

Keon entered the competition as a way of improving his CAD (Computer-Aided Design) skills and of engaging in the Polar Cloud platform – “essentially a workplace for engineers and designers to post and share their work…a STEM-oriented ‘Facebook’.

“I was frankly stunned when I found out I won the competition: the effort I had given it was extraordinary, so I felt it was definitely worth my time,” said Keon.

He added that he had surprised himself with the level of dedication he had brought to the competition, but feels that this will benefit him in the future, not least in terms of his schoolwork.

Experts have been helping QE A-level students see the exciting topical applications of their subjects in the real world in a series of lectures streamed into the School.

Sixth-formers have already enjoyed stimulating day-long sessions on Medicine in Action, Chemistry in Action, Product Design in Action and Geography in Action, with a similar event for Biology due to take place in December.

The training days are run by The Training Partnership, the leading provider of external educational study days in the UK, and would normally be held in London, but are this year being conducted remotely because of Covid-19.

QE’s Head of Technology, Michael Noonan, said that the Product Design A-level students, and even a couple of “enthusiastic non-subject specialists”, enjoyed a “superb day” of lectures. “Favourite amongst the talks attended by students was Pioneering aeronautical innovation by Sam Rogers – an aeronautical engineer working in product development for Gravity Industries, a company who are currently developing a jetpack suit.”

One of the pupils attending, Paul Ofordu, of Year 12, said: “It was amazing to see the application of prototyping, testing and iterative design in such a high-end product development project.”

The Resourcefulness and design lecture, delivered by Kingston University Senior Lecturer Pascal Anson, stimulated a practical activity, pictured. “Here we see some examples of structures which were resourcefully developed by the students using VEX IQ and EDR Robotics game elements – great thinking on their feet!” added Mr Noonan.

Chemistry students gathered in the Main School Hall to hear engaging contributions from speakers who ranged from Andrea Sella, a synthetic chemist and broadcaster, talking about mercury – “the most beautiful element in the periodic table and the most reviled” – to marine engineer Hayley Loren exploring whether nuclear fusion could provide the solution to the world’s energy issues.

Julia Lister, QE’s Head of Chemistry, said: “The engaging Chemistry in Action lectures covered an array of topics. Streaming these lectures took students from key concepts to cutting-edge science and future directions across many applications of the subject.”

The Geography lectures were similarly wide-ranging. One talk, entitled Lessons in sustainability: An explorer’s tale, was by Jason Lewis, the first person to circumnavigate the earth without using motors or sails. Another featured academic Martin Evans, from the University of Manchester, speaking on Landscape Systems in the Anthropocene. And Emily Parry, Head of Geography, highlighted lectures on water insecurity and on how COVID-19 has impacted the Pacific Islands.

“The boys enjoyed the talks, which both built up content covered in their A-level course and extended their knowledge on a range of issues facing the planet,” she said.

“Each lecture was followed with a Q&A session in which the boys could send in questions to the lecturer. Often questions focused around what young people themselves could do to help address some of the issues explored such as climate change, river pollution and how we choose a sustainable future.”

Head of Biology Gillian Ridge said that after the forthcoming Biology in Action day, boys who attend will be invited to give a series of lunchtime presentations to the rest of their year based on the talks.

A Year 8 boy has won a national Covid-19 health & safety competition with a colourful design inspired by Lord Kitchener’s iconic World War I recruitment poster.

Anik Singh won the secondary school category of the contest with his watercolour highlighting some key coronavirus safety precautions.

Anik, who is keen on both Art and Technology, was congratulated on his success by Head of Technology Michael Noonan: “This is a tremendous effort from Anik, and it’s brilliant to see him take the influence of historical events in his work. I hope this competition win spurs him on to even greater heights.”

In recognition of his success, competition organisers at e4education, the leading school website provider, had 50 copies of his poster professionally printed. These have now been distributed around the School, complementing QE’s own Back to School Guide and accompanying anti-Covid 19 posters and banners.

In the design, the familiar Kitchener figure looking straight out of the poster is transformed into a masked medic. Under the main title ‘Your country needs YOU to follow the advice and rules’, are references to three specific measures: “Always try and stay 2M apart”, “Wash your hands frequently for 20 seconds with soap” and “If you use public transport, wear a mask”.

Anik said he had aimed to make the poster as colourful as possible, so that, in his words: “You should want to stop and look at it.”

Katie Sixsmith, Marketing & Communications Executive for e4education, explained why the design had so impressed the judges. “We were blown away by the technical skill of this drawing and loved the multi-coloured effect combined with the themed interpretation of a historical poster.”

Year 11 pupil Ashwin Sridhar has crowned a series of wins in competitions he entered during lockdown with outstanding international success in the prestigious Microsoft Imagine Cup Junior.

He was named among just three winners from across the vast EMEA (Europe, Middle East and Africa) area after designing an artificial intelligence-powered device to help tackle the crisis in care for the elderly. Ashwin was one of only nine winners across the whole world and was the sole UK winner.

The same design also brought him success in another competition – the Connect the Community: Design Challenge – where it was named among the 10 winning entries in phase 1 of the challenge.

Congratulating him, QE’s Head of Technology Michael Noonan said: “Ashwin is an outstanding Technology student who has had a tremendous year. Despite the challenges of the school closure, or perhaps even taking advantage of them, he threw himself into many competitions using his vast technological experience. He was successful in eight competitions on a local, national and, with his latest win, international level. He should be extremely proud of his achievements this year, and he undoubtedly has a bright future ahead of him!”

Like the Imagine Cup, Microsoft’s sister competition for older students, Imagine Cup Junior provides those aged 13 to 18 with the opportunity to learn about technology and about how it can be used to positively change the world. In 2020, the competition was focused on artificial intelligence (AI), with participants challenged to come up with ideas to solve social, cultural and environmental issues.

Ashwin’s design, named AI RetroMate, is an all-in-one solution to help the elderly and carers with their everyday lives. An Internet-connected hub that dispenses, chats, and detects loneliness, AI RetroMate is controlled by a virtual caregiver and aims to support independence for elderly people who require care but want to stay at home.

Its features include:

• A remote connection that uses cellular IOT (Internet of Things) technology to keep carers and patients connected reliably and securely, thus helping reduce the cost and strain of full-time care
• A ‘chatbot’
• A remote hub with a built-in a pill dispenser, incorporating facial recognition for additional safety
• An attractive retro design.

After first researching online, Ashwin entered the cup competition, using AI to develop and prototype the device. As part of the project, he had to delve into advanced Mathematics to help enhance the prototype, using, for example, ‘nearest neighbour’ algorithms and linear regression models.

Ashwin developed his project late in lockdown, deploying CAD (Computer-aided Design) and electronics to create a prototype, using skills that he had learned in Design and Technology and in Physics.

Speaking on behalf of the judging panel, Tina Jones, Business Strategy Lead, Azure Skills and Employability, said: “The judges were thoroughly impressed by AI RetroMate, especially the research [Ashwin] had undertaken into the difficulties faced by the elderly and by carers and how to create something to improve the quality of their lives.

“We particularly liked how [he] added a chatbot following initial product feedback, and the video, and how [he] brought the product to life with [his] CAD drawing was incredible.  [Ashwin’s] concept, ethics and use of AI was thorough, well thought-through, and it was clear how much effort [he] had put into [his] project.”

Ashwin, who won a trophy as well as a prize of Microsoft’s Surface Go tablet computer and case, said: “This project has helped me to explore STEM [Science, Technology, Engineering & Mathematics], using and developing skills from class to help solve real-world problems.”

In the Connect the Community: Design Challenge (run by RS Components, Nordic Semiconductor and Cadent), having been chosen as one of the international winners of phase 1, Ashwin is now working towards a final prototype, in time for the second phase, where he could receive the funding to help to bring his product to life.

A Year 10 team’s hi-tech lockdown project was placed third in an international competition aimed at stemming the global tide of plastic pollution.

The Prata Neptunia team combined their skills in Technology, Mathematics and Chemistry and also produced a slick video presentation to promote their design for an autonomous hovercraft robot.

Competing against teams from more than 40 countries, Ashwin Sridhar, Anish Rana and Merwan Singh impressed judges from the British International Education Association with their use of artificial intelligence to tackle plastic waste in rivers and canals, reducing its harmful effects on flora and fauna.

A second QE Year 10 team, called Ocean, won the Best Effort prize in their category in the competition, which was launched in January.

Head of Technology Michael Noonan said: “My heartfelt congratulations go to the boys, who began their projects when we were deep in lockdown and thus had to overcome some significant obstacles in putting their entry together. Although narrowly missing out on the grand prize, the team are proud to have had their project acknowledged on an international scale and to have learned countless new skills along the way.”

The BIEA International STEM Innovation Challenge invited young people from the age of nine to 21 to research, write a report and design a solution to Save our shores from plastic waste through STEM (Science, Technology, Engineering, Mathematics). In its brief, the BIEA pointed out that one lorryload of plastic is dumped every minute worldwide – the annual equivalent in weight of 40,000 blue whales or 1.6 million elephants. The competition drew entries from schools in countries including China, the United States, Argentina, Norway and Indonesia.

Ashwin took on the role of Project Manager and Lead Scientist for Prata Neptunia, while Merwan was Lead Researcher and Anish the Lead Robotics Designer.

By using hovercraft technology informed by artificial intelligence, the trio were able to devise a design that could travel across multiple terrains, both land and water, and target different types of plastic. These notably included microplastics, which have become a huge problem worldwide because of their devastating effects on marine life.

The team learned project-management skills in order to optimise their time effectively, from the use of Gantt charts to task delegation. They designed prototypes at home, building and testing parts, and investigating processes to remove microplastics in order to determine the feasibility of their design.

As part of the overall design process, they applied skills acquired in Technology lessons before finally designing their solution on CAD software.

Their work led to an invitation from BIEA to participate in the virtual international finals, where they were awarded their third place in the 15-17 category.

Anish said: “We started our journey back in March and were quite behind, compared to other teams, which started earlier. However, through thoughtful planning and hard work, we were able to pull together to create a product we were proud of in time for the due date.”

Unable to meet up freely or access all the resources of The Queen’s Library, the boys worked from home and used technology including Zoom calls to co-ordinate their work.

“We all saw plastic pollution as a big problem all over the world: the BIEA competition has targeted a global crisis that needs fixing.”

The competition gave him and his teammates the opportunity to deploy their skills and knowledge to tackle this crisis, which, he said, has shown him “how we can all work together to solve it”.

Anish added: “Of course, we had our ups and downs, but overall the competition was a great experience with a satisfying conclusion.”

The trio’s project required some fairly advanced Science, as they investigated methods of removing plastics, which led to their inclusion of PETase, an enzyme which catalyses the hydrolysis of Polyethylene terephthalate (PET) to monomeric mono-2-hydroxyethyl terephthalate (MHET). MHET is then broken down into Ethylene glycol and Terephthalic acid (Benzene-1,4-dicarboxylic acid) using the enzyme MHETase.  The team also delved into fluid dynamics – encompassing Mathematics and Physics – to optimise their design’s motion and efficiency.

The Ocean team, Jashwanth Parimi, Utkarsh Bhamidimarri and Siddarth Jana, also started their project relatively late and had only about a month to complete it.

Jashwanth said: “During multiple Zoom calls, we learned much more about plastic pollution and, eventually, we designed an idea that we thought was suitable for solving the problem. Then we each split into our specialised areas to fulfill the requirements of the project, but we still all helped each other in each of our project areas until we finally finished.”

The team designed a multi-terrain vehicle that used a net in order to collect macro-plastics on both the ocean and the mudflats. “Our project was innovative since we tried to consider all the wildlife on all the terrains, such as fish and snails, and so on.”

A Year 12 team won both the prestigious Innovation Award and the new People’s Choice Award at the SECBE Constructing Excellence Awards.

Competing against entries from leading professional construction firms, QE’s four-strong Engineering Education Scheme team were rewarded by the judges for the strength of their design project aimed at reducing the risk of injury from band saws.

Headmaster Neil Enright said: “My congratulations go to the team on what is a great success both for them and for the School. Their very impressive submission evinced not only innovative thinking and a sound understanding of engineering principles, but also meticulous implementation and very effective communication of their ideas.”

Thomas Mgbor, Hugh Westcott and Kai Sethna donned black tie to take part in the awards ceremony, together with Technology teacher Tony Green. (The fourth team member, Brandon Ionev, was unable to take part because of an examination.)

Mr Green said: ‘The boys deserve all of the plaudits that will come their way for an outstanding performance.” He thanked all in the Elizabethan community who supported the team in their bid to win the People’s Choice Award, which was decided by popular vote.

The team worked with office design specialists Morgan Lovell on the project, which involved a number of suggested improvements to band saw guards and dust extraction systems. Tweeting their “huge congratulations” to the QE four, Morgan Lovell said: “We’re really proud to be alongside the engineering minds of the future”.

During visits to construction sites, boys saw that workers would often not use the blade guard fitted to existing band saws, because it was time-consuming to reset the guard manually each time to adjust it for different thicknesses of material.

To address the issue, the boys conducted extensive research over six months. They came up with three designs, all based on the same concept. The material pushes against the bottom of the blade guard, causing a force that pushes upwards and adjusts the blade guard automatically to the correct and ideal height for cutting. With no user input needed, saw operators could then work in the same way as before, but much more safely.

An additional benefit of the designs was that they incorporated significant improvements to the existing dust extraction systems of saws, thus reducing dust exposure – another health & safety concern – and allowing a more precise cut to be made because of the enhanced visibility of the cutting service.

The designs would work with different types of saw and, unlike existing guards, they covered the blade from multiple angles, which is another safety improvement. Because they could be retrofitted to existing machines, the guards hold out the promise of improving safety without huge expenditure. The boys were assisted by their industry mentor, representing Morgan Lovell, Health, Safety & Wellbeing Manager Alex Wood.

Team leader Thomas opened the team’s presentation to the judges at the virtual awards ceremony, before Hugh and Kai went through it in more detail. They faced some tough questioning from the judging panel, which comprised Chris Blythe (Chairman of SECBE, a construction industry not-for-profit company working towards positive change in the sector), Bill Ferris OBE (Chief Executive of Chatham Historic Dockyard Trust), James Wright (Framework Manager for Southern Construction Framework) and Julie Barry (Head of Business Development for RIFT R&D).

“Later in the day, we pushed for the People’s Choice Award on social media and won that award, too!” said Thomas. “It was a really enjoyable day to showcase our young talent and ‘show up’ some of the professional construction firms. In the words of SECBE, we were ‘recognised as the best’, and hope to inspire the rest.”
