Robots
I have a couple of ideas in mind for the robot platform I built awhile back shown below.  It's a basic system with differential drive, where the wheels on each side of the robot are attached together via a belt.  There are two Maxon motors, one for each set of wheels.  The aluminum chassis is rugged and practically bombproof.  Already on board is a line tracking sensor that I designed over two years ago (read the article).  Machined out are sockets to fit the Sharp IR proximity sensors and there are a total of seven sockets, which means a whole lot of proximity sensing!  The microcontroller shown on this platform is the MIT Handy Board, which I built from a kit.  I'll see how far I can take the Handy Board, but more than likely will switch for a more powerful processor.  I'll need some brain power to get this platform up and running in style.  Some of the components I'm considering include:

• Wireless CCD camera for video feedback
• Seven Sharp IR proximity sensors
• A couple of Polaroid sonar sensors
• RF communication system
• Some sort of navigation sensor, perhaps a digital compass
• Maybe some accelerometers
• and the list can go on. 

When I find the time, I'll update this page and the progress of the robot.
