Rev your engines because this isn't just a race. It's a test of how well you think on your feet, solder under pressure, or explore a new field in engineering.
Circuit Metanoia challenges engineering teams to design and build a remote-controlled toy car from identical components, then run it through 5 laps of a 25-meter loop as fast as mechanically possible.
