user8046: I am looking into building a robot with my Arduino Nano but I don't want to shell out more then 50 bucks. Does anyone have any suggestions for a four wheel robot chassis at this price that I could use to make my robot mobile?

user7856: There's plenty of options on ebay, you will have to add a DC motor driver and optionally, sensors, but these are a good starting point.
