Team Bath Racing
Building on an existing relationship
Every year, a team of engineering students from the University of Bath competes in the Formula Student motorsport competition. The competition challenges student engineers to design, build and race a single-seat car over a two year period. Known as Team Bath Racing, the University of Bath students are the most decorated British team in the entire competition.
As a community outreach project, Rocketmakers designed an augmented reality (AR) model for TBR’s 2017 car. The model was displayed on the Microsoft Hololens headset, and used as part of the students’ presentation to judges. This presentation was an important part of the overall competition, although not nearly as exciting as watching the car’s time trials at Silverstone.
In the Autumn of 2018, Rocketmakers and Team Bath Racing decided to collaborate again, but this time to raise the stakes. The goal would be to create an AR-powered tool which would be used in the construction of the 2019-model car.
Conceiving the world’s first AR automotive construction tool for competitive race car construction
Both teams wanted to create and test a tool which was genuinely useful, could operate easily within the constraints of current AR headset technology, and required minimal advance work by the students. Various ideas for how to deploy AR technology were considered, including an option which would allow the students to plan the placement of the engine, brakes, and drive train in 3D.
Working within current state of the art technology
Once conceived, the idea for the new tool required extensive experimentation to get right. To work effectively, the Rocketmakers team would need to push the limits of Microsoft’s Hololens headset to its absolute limits.
Although the Hololens was the most powerful commercially-available headsets at the time, the complexity of virtual images they could display was still limited. Team Bath Racing had a set of 3D CAD files for every part of the car, but these included too much data for the Hololens to process. The Rocketmakers design team had to develop a system for converting the CAD files into something the Hololens could process while still retaining enough information to ensure the AR tool was useful.
Once the Hololens could process the images, the Rocketmakers team added data displays to show the correct shape, location, and orientation for each carbon fibre laminate. This allowed the wearer to clearly see exactly where and how to apply the laminate as he looked at the car body, with no need to look away to a computer screen.
A world-first for competitive race-car design
With a Microsoft Hololens in hand, the Rocketmakers team travelled to the Team Bath Racing workshop on the University of Bath campus in May 2019. After some initial testing, the new tool was used to lay the first carbon fibre laminate laminates, and history was made!
Although augmented reality had previously been used in demonstrations by car manufacturers, this is believed to be the first time the technology will have been used to build a car intended for use in competitive racing.
Global press coverage
Rocketmakers was contacted soon after the story appeared by engineers from the Renault Formula 1 team, who requested a demonstration of the new technology in person.
Thanks to its work with Team Bath Racing, Rocketmakers was also selected as the winner of the Most Exemplary use of Virtual or Mixed Reality category at the 2019 Sparkies Awards, run by TechSPARK.
Rocketmakers incorporated our 3D model into a mixed reality platform so that our visualisation capabilities have exceeded anything that we've done before.
Rocketmakets introduced us to the Microsoft Hololens which allows us to bring interactive animations and holograms into a real world environment. It's going to be invaluable to all our designs.
We took this 3D model and developed it into an augmented reality space, where a Microsoft Hololens user could then interact with the car. Using the Hololens, users can select different race car components to analyse aerodynamics, crash impact, manufacturing materials, and structural connections.
