Custom robot beach wagon design and build

A video describing the development and operation of a semi autonomous beach robot [a red wagon] that saves me a lot of work hauling chairs and umbrellas etc. over the dune and down to the water. Plus it's good for giving rides.
The secret sauce is used wheelchair motors, ruggedized Arduino Mega and a Teensy 3.2, Dimension Engineering SaberTooth motor controllers and Wheeleez sand tires. Plus a lot of C++ code to support the packet radio control system, and the driving commands.
