Abstract
A steering system for craft turns a motor from a fixed position to a secondary position. As a result, the craft turns right or left as desired by a user of the craft. A control unit instructs the steering system to turn the craft to a desired orientation. A steering motor is activated that turns a cam attached to a shaft. The shaft is attached to the motor. The cam also includes an indent and sensors to indicate when the motor is in the fixed position or a secondary position that corresponds to a maximum angle for turning the motor. The steering system returns the motor back to the fixed position when the user indicates the steering system is to stop turning, or when the secondary position is reached. The steering system returns the motor back to the fixed position without knowledge of the user. Thus, the motor stays in one of three positions unless instructed by the control unit to turn.
