Wannes Vermeulen created an iPad app to control a modded RC car, complete with a remote point-of-view camera:

I used two servo motors attached to the original remote control of the car to adjust speed and steering. These are controlled by an Arduino Uno, which gets the accelerometer data from the iPad through a socket server on my laptop. I also fitted my old Android smartphone to the car, which uses an IPCam app to stream the video to the iPad. The “camera”, the iPad and the laptop are connected to the same Wi-Fi network to share their data.

Wannes created the project for a class in New Media Development at Howest.
