Abstract
A method for positioning a mobile platform at a station that includes moving the mobile platform near a bumper by applying torque to a drive shaft. The mobile platform is maneuvered until a contact stop of the platform is touching the bumper. A locking mechanism is engaged to the mobile platform before the torque to the drive shaft is released to assure position retention at the station. A system for precise positioning of a mobile platform at a station is provided that includes a stationary bumper at the station. A mobile platform has contact stops, a drive shaft, and sensors for measuring contact with the stationary bumper. The mobile platform having a locking mechanism for preventing movement of the drive shaft in response to input from at least one of the sensors in response to contact with the stationary bumper to provide the precise positioning of the mobile platform.
