I've put a photo of my current robot in the 'photos' section. It's
about 30x30cm, uses a cheap RC crazy car (called ugly predator) as
the base with all the electronics disabled, and has a couple of
sensors (rotating sonic rangefinder, ir rangefinders, odometry)
motor driver and mcu on it. It doesn't do too much other than
wander around at the moment (it would be good to give it a goal) but
it's good for trying ideas.
