Here is brief video of a white line follower robot I programmed. Well white line folower robots are no big deal if you are not really using PID control. In this video the robot is completely dumb. All the sensor values to my machine through a Xbee communication module (wireless) and I use a python program to control the bot.
Another good news is that the much awaited beaglboards finally arrived. This is seriously a great piece of hardware. I just finished installing Angstrom linux onto it along with a python interpreter. Hopefully this will result into more work.
