Using my RedBot BoosterPack I have created a small remote control robot. The motors + chassis costs $15 from SparkFun so it's a pretty low cost solution to get started in robotics.
On the controller side I use the CC1101L for wireless communication and the Educational BoosterPack MKII for the joystick. The F5529 LaunchPad simply reads the joystick value and decides which way the robot should move and transmits the data using the CC1101L. Here is a picture of the controller, note the CC1101L is on the bottom of the LaunchPad to make the joystick easy to use.
On the robot side the F5529 LaunchPad is connected to the CC1101L BoosterPack to receive the data from the joystick. It then uses the RedBot BoosterPack to control the robot.
The GitHub repository is located here, which includes hardware + software. The remote control code isn't uploaded yet but will be once I clean it up.
And now a video of it in action (phone quality).
