My wireless rover, based on a Traxxas Stampede XL-5 and powered by a Raspberry pi, controlled over wifi.

An Adafruit 12bit, 16 channel PWM servo driver is used to control all of the servos, including steering and throttle.

The Traxxas XL-5 speed controller provides the LiPo cut off protection which activates when a single cell goes below 3.2 volts.

A miniature USB WiFi module is used for wireless communication. As of this posting, the rover hosts a python TCP server and a windows WPF application is used a as client.

 

For mounting all the electronics, I simply used another stampede chassis, mounted upside down.  The raspberry pi sits nicely where a battery would go.  The bonus part is it already has mounting for the servos and all the holes line up.
