gRover Robotics Platform

gRover Robotics Platform

This is gRover, the Grove-Platform Rover; it is a general, all-purpose rover for house exploration.

Foreword:

This page is a bit of a mess, I'll admit. The PDF file attached is much neater and contains much more information about the project than this page's text does. For more pictures, see the gRover Flickr Photoset. This rover build uses parts graciously provided by Seeed Studio.

On the bottom of the PCB, we have the following chips:

Flambeau Brake Control Demo Kit

Flambeau Brake Control Demo Kit

This is a nice item that I found today at Princess Auto... A grey box hiding on the bottom of a grey shelf. The phrase "Demo Kit" caught my eye, and I had to take a peek inside. I was blown away by the beautiful innards, and I just had to have it.
