This is my entry for the toy contest and the make it move contest. Please vote when voting time arises!!!
It uses 2 motors to steer and drive forward and backwards and two more for the claw - one to operate up and down and the other to make the claw open and shut. Most of the pieces are from the Lego power functions bulldozer but the claws are from a Lego power miners set. It took me around 3 - 5 hours after I had thought up the idea to make it and then more time to perfect the grabbing claw. It isn't the most secure of vehicles but I like it.
