On a previous blog I bread-boarded a PICAXE processor and worked out how to decode an IR hand-held remote control. In this blog, the circuitry has migrated to a toy tank platform so I can test out some ideas I have for a larger, outdoor robot on a much lower cost platform (this was built for less than $60). Most of the parts were purchased from Pololu and SparkFun (and Rat-Shack). Using an IR link costs very little compared to a RC system, so it was ideal for this project. I really enjoyed putting together all of the mechanical elements supplied by Tamiya.
