Remote control cars are interesting, but as Leon van den Beukel shows in the video below, an RC forklift can be even more challenging and fun to create. 

His project was constructed using a variety of hand and automated techniques, resulting in a build that can easily manipulate tiny pallets. Forks are lifted into the air via a motor and belt assembly, and tilted with a small servo.

The device uses an Arduino Mega for control, and is linked to an Android phone over Bluetooth for user interface. Code, along with STL files and drawings, are available on GitHub and the custom Android control app can be found here.
