Remotely control a sumo bot with a gaming wheel
Using an Arduino Uno, Nano, and two Bluetooth modules, engineering student “Roboro” can now remotely control his sumo robot.
Like many hackers, Roboro had an old gaming controller that he wasn’t using, in this case an Xbox steering wheel and pedals. Naturally, he converted it into a controller for his sumo robot, which can now be driven manually. This involved wiring the wheel controls into an Uno; the smaller Nano was used onboard the bot.
Rewiring a controller is nothing new, but what is also quite interesting from a hack point of view is that the Arduinos communicate over Bluetooth. When initiated, the controller connects itself to the robot, which can then be driven around (as long as it doesn’t get stuck in the hardwood).
