In this design a sloped front makes up half of the front face, and this will be used to lift the car jack by running into it. The other half of the front face consists of a disk, this disk will be used to drive up against the fuel crank, and a motor will rotate it in order to spin the fuel crank. Attached to the top is a rod with a stopper attached, that will be used to secure the wrench. All of the buttons that need pressed will be pressed by either running the robot into them or pushing them with the rod. The chassis of this design is constructed out of PVC.
Pros: ease of control and cost
Cons: average accuracy, speed, and consistency
