This is the project I started after being laid off in the 2007 economic freakout.
It really did help me feel busy for those sore months of holidays.
But hey - the old firms partners need their race car teams and other perks, right!?
This was built around wheelchair motors and CNC cut baltic birch. Visual C# was used for telemetry control and Mikroelectronica 'MikroC' was used for PIC 18F4550 USB hardware interface on the robot.
One thing I learned that should be passed on: a 3 wheel robot base is unstable and will not be able to turn on even mildly uneven terrain.
It can turn... But it also throws itself over onto the ground.
