Lego Mindstorms NXT Split Chassis Steering
Here is an idea I have been playing with for a little while. Instead of simply doing a car with regular steering, I wanted to try a split chassis design where the front of the car rotates in the direction you want to turn. Here are two attempts, but I abandoned any further design after driving both around with my phone via bluetooth. The steering is too inaccurate to use for an autonomous robot, but it is fun to drive.
