Arduino-powered mini sumobot
I came across an article on instructables by Angelo (aka ASCAS) where he discusses building a mini sumobot powered by an Arduino. The one in the article also features bluetooth connectivity so it can be controlled via smartphone, but the autonomous portion of the robot is relevant to our club's uses. I decided to try building something similar, expecting it to be significantly cheaper than using the Mindstorms sets, and it should also be more powerful as we can use bigger motors.
