The Hardox armouring is free-moving, meaning that although it is connected to the robot, it is free to spin around freely. The attaching part is a 4mm Hardox tube which the Hardox armouring slips over. This is opsitioned in the middle of the robot.

The above would be much easier if I had a diagram.

In terms of batteries, the robot has 6 x 24v 3600mAh NiCD Battlepacks.
