Front View

This image shows the gearing used in Grendel's wheels. With the two motors and separated garing, Grendel has the ability to turn left and right in his search for Danes. Eventually the two 16-tooth gears shown in the front of Grendel were switched for an 8-tooth and 24-tooth gear combo to provide more torque.

Back View

The Back view of Grendel shows the placement of the cricket and the center red lego support beam that allows the gears to opperate separately in the front. This beam free the grears from the need to be attached on a single axle.
