What does it do?
Hello everyone, I’ve posted a lot on LMR, and I build robots for a living, but this is the first time I’ve built a personal robot that I’m able to tell you all about. First off, I got this idea from Fritsl (http://letsmakerobots.com/node/928 ) and I decided I wanted to build a pair of wall racers for my nephew who has always asked me to build him some robots. If you’ve never heard of a wall racer it is a modified RC car with two sonars, one pointing forward the other pointing to one side.
