Arduino RobotsJul 4, 2009 Edit
A few days ago I saw some videos of sumobots (Robot-sumo, or pepe-sumo, is a sport in which two robots attempt to push each other out of a circle (in a similar fashion to the sport of sumo). The robots used in this competition are called sumobots.) on robots.net and youtube.
Instantly fell in love with the idea and started looking for a local robot club that did compations. http://vancouverroboticsclub.org/ came up first in google. They do run regulate contests such as Basic Table Top Challenge that look interesting. I was looking for something more competitive but its as good as any place to start.
I ended up buying a motor shield from http://www.adafruit.com/ that worked perfectly with my RC car that I bought a few years ago. After a few hours of tweaking I was able to write a simple API to control it properly. The RC car only really has two speeds, really really fast and reverse. So it speeds thou the course I programed a little too fast.
Next is to add sensor to it so it drive its self with out predefining the path. I ordered some medium and short range ultrasonic range finder and a few other toys to play with.
