When moving, Groundhog consumes upwards of 1kW of power. This is the story of how that power is supplied, distrbuited, controlled and ultimately used.


Body of an ATV, Soul of a Golf Cart
Based on the batteries, motor and wiring of a golf cart, the electric Groundhog was controllable by button box within a few weeks of the projects inseption.

Controlling the Current
The high DC currents made computer control of the robot a multi-layered problem.

The Brain Behind The 'Bot
No robot is complete without a computer. Groundhog's PC104 stack controlled the robot and record all the sensor data will still being smaller than a breadbox.

Lasers and Cameras and Lights, Oh My
Groundhog's many sensors, and how they integrate together.
