Dynamo existed from October 2004 to June 2004, when it was too badly damaged to repair easily. It was meant to be Nathan's robot, as at this time (he was six) he had trouble driving a robot and operating the weapon as well.

I used four servos paired in two to a receiver. The trick was to centre both matched servos to the same calibration, or they would be pulling at each other instead of working in unison. See the "How To..." pages for more information on calibrating servos.

See the following pictures for the story of how Dynamo was built.
