Peanut Tin of Terror
Peanut Tin of Terror is an autonomous beetleweight (3 lb) combat robot. He competed in this year's Robogames 2010.

While I have created many robots before, this was my first experiment with a combat robot. It was really fun.
Peanut Tin uses two Ping sonar sensors to detect walls and a motion sensor to detect opponents or know when it is being struck. I have included a test video to show more about how it works. I took some video of Robogames so I will put them up.
While I consider Peanut "complete" since it competed, I have plans to make a better version for the next tournament.
