Abstract/Artist Statement

This project details the design and fabrication of a creeper that allows for easy maneuverability through its low profile design and transforms into a stool by automated means. The idea for the project came from recognizing a need for a more effective creeper to provide convenience, relieve joint stress on mechanics, and minimize the risk of injuries associated with jacking up the vehicle. The design for the lifting mechanism mimics that of two simple carjacks aligned in parallel and run by a battery powered drill motor and chain drive. The design is simple, but robust, easily meeting the design requirement of lifting 300 pounds from the laying creeper position to up to 20 inches in the upright stool position. It is switch operated, has magnetic tool compartments, and the creeper lifts to the stool position in less than 6 seconds. Overall, the majority of the design requirements were satisfied in the finished steel prototype. What has been left to be implemented is a back support mechanism. This was part of the original design objectives, but proved too difficult to add to the current design without significant risks to product safety. A back support mechanism would be re-implemented in future iterations.
