A battery-powered collar with an array of sensors in a gas-bottle collar, developed in just seven weeks by UNSW engineering students, has won the inaugural Maker Games, giving the five-strong team an all-expenses-paid trip to Silicon Valley.
The a rapid prototyping competition, in which industry giants submit their wicked problems and undergraduate students solve them in a flurry of ingenuity and engineering nous, began in July with almost 1,000 students signing up to develop ideas. In the finals, held over the weekend, 86 students in 17 teams battled it out for the $25,000 prize.
The winner, decided at a five-hour pitch and demonstration session, was Team Raven, who impressed the judges with their ‘Internet-of-Things’ (IoT) system for tracking gas bottles.
The sensor-laden collar is an integrated hardware and software suite for tracking and management that connects gas cylinders to the cloud and allows them to communicate with each other and its owners anywhere in the world.
The winning team – Henry Blumentals, Matthew Eyles, Vanja Videnovic, Michael Irwin and Matthew Buffa – took advantage of their different specialities in computer science, mechantronics, aerospace and renewable energy engineering to develop a working prototype and tested it by moving gas cylinders around UNSW’s Kensington campus, tracking it via long range radio (or LoRa).
The collar uses a suite of sensors – including a gyroscope, GPS module, temperature and pressure sensors – that integrate into an IoT network via a low power, long range satellite communication antenna and radio, with a collar made using 3D prototyping.
“The key goal for a gas bottle company is to never leave an empty cylinder in the field,” said Blumentals, a renewable energy engineering student at UNSW.
“Cylinders often go missing or are mishandled, or distributors don’t know when they need to be refilled. Our system indicates when cylinders are spent, where they can be found, and where they are during transport, minimising down time.”
None of the team had used LoRa before. “We learned a ridiculous amount,” added fellow member Eyles, an aerospace engineering student. “It would have been impossible without a collaboration between all our different disciplines. We had to teach ourselves a lot of stuff on the fly, and gained skills that you can’t get anywhere else.”
“The prototype is well thought-out, and goes beyond just tracking, which is a very common IoT use case,” said Jeff Apcar, a Distinguished Services Engineer at Cisco, one of the companies participating in UNSW’s Maker Games, who acted as a mentor for Team Raven.
“What we get out of this is a working prototype that we can then use in our demonstrations. It’s just phenomenal. It’s fantastic. I’m very proud of them.”
The Maker Games is the brainchild of Mark Hoffman, UNSW’s Dean of Engineering. “We’re not trying to teach a solution to the students – we’re trying to teach the ability to ask the right questions, so they can themselves develop the right solutions. Unless you’re actually working and trying to solve problems, it’s difficult to know what questions to ask.
“This is the best way you train engineers; to be like entrepreneurs who develop ideas and innovate to solve real-world problems. The Maker Games is perfect for this – we match industry partners who have really wicked problems, with the brightest engineering students, who are keen to apply the knowledge they’ve gained at UNSW to solving real world problems.”
Those curly problems were provided by nine leading companies: Cisco, Commonwealth Bank, Telstra, Transurban, Phillips, WSP, Westfield, Rebel Sport and Vertiv Co.
From 115 pitches, the industry partners selected 17 teams of four to six students whose proposals they wanted to take forward and mentor, working with the teams over seven weeks to help refine their ideas.
Another team, Find Your Future, harnessed data supplied by Commonwealth Bank to develop a web app for people facing a career transition. “We’ve had data scientists, people in strategy, people in technology who have been able to mentor us through this process,” said team member Linda Zhang, an electrical engineering student.
“They let us know what data sources are available and helped us build something that is not only feasible but marketable.”
William Weng, a computer science and mechatronics student of Team Tiptap, acknowledged the importance of feedback from real users. Tiptap’s challenge was to make the Commonwealth Bank’s Albert payment stations more accessible to customers with visual impairments.
Early prototypes were “a bit confusing”, said Weng, but the team used that feedback to improve later iterations.
Another group, Team Foresight, created an augmented reality Android app that superimposes construction industry design files onto a mobile phone camera image, allowing users to visualise hidden infrastructure such as pipes and wiring.
Member Ainharan Subramaniam, a computer science student, credits their industry partners Westfield with expanding the team’s ideas and helping them think about its broader applications.
Team Soaprise developed a prototype system for removing detergents from water used to wash road tunnels for Transurban, and a visit to the Lane Cove Tunnel helped put the problem in context.
“Studying isn’t just about sitting in a lecture,” said member Jason Wooi, a nanoscience and nanomaterials student. “When you’re actually doing something, that’s when you really learn.”
Danielle Neale, Entrepreneur-in-Residence at UNSW Engineering who co-ordinated The Maker Games, was delighted with the result.
“It’s been the most successful undergraduate exercise of this kind we’ve ever had. Students have taken up difficult industry challenges, and done so with gusto. Some of the ideas are really innovative, and those ideas are getting prototyped into products and solutions that are coming to life before our eyes.
“Based on the success of the showcase, we have had a number of exciting enquires from potential partners and investors who want to be involved in The Maker Games in 2018 and beyond,” she added.
The five members of Team Raven will take their all-expenses-paid trip to California to visit Silicon Valley icons and all the hot new start-ups later this year.
