There's an "Bristol Bot" here http://jp.youtube.com/watch?v=rUSTXUis_ys and I imitate it. Because I used a battery box and mouted a motor on it, center of gravity is too high and the bot easily falls down. So I added a balance leg around it. This is a tin plate wire solderd to the battery terminal.YRZ25http://gdata.youtube.com/feeds/api/users/yrz25Tooth brush robotRobot that is made from old tooth brush and small vibration motor.
