This is a quick video describing my robot Spyder's orientation sensing. There is a metal and ceramic encapsulated mercury (Hg) switch near the rear of the robot. This ties into the motor inhibit/enable circuitry in the conditioning board. It shuts off drive to the H-bridges, saving power and keeping the robot from squirming when picked up and handled. <br /> <br />For more info, please visit and Enter the page below and click the "Robotics" link in the navigation bar. <br />http://richfiles.solarbotics.net
