Twisted Thruway is one of the most popular exhibits at the National Museum of Mathematics. Three remote control cars run on twisting tracks, defying gravity using magnetized wheels. They are each controlled from a driver's seat where a visitor can steer the car and see on a display live video transmitted from a camera mounted on the front of each car.
Unfortunately due it’s complexity and age, it is one of the most temperamental and unreliable exhibits, requiring constant maintenance to keep it working for longer than a day or so. During my time working at Momath I have taken the initiative to redesign significant components of this exhibit in order to allow it to function much more reliably and consistently without maintenance.
