In this project we hacked an RC Car (Maisto Rock Crawler) and replaced it’s stock circuit board with an Arduino Uno R3, Motor Shield, and XBee module. We used another Arduino to collect and interpret data from an Xbox 360 controller; this Arduino had its own XBee module, which sent instructions to its XBee pair located on the Car.
You can find a full step-by-step instructable here. (Has become a featured technology project on instructables.com)
Please also look at my GitHub, which has a fully updated README.md (includes in depth details regarding the project -plus references).
Also, please reference the power point recap (RCcar), which has details such as: Our Project Purpose, The Technology Learned, and Future Options for our Car.
