Hobby servo motor linear actuator systems are provided. The system and method sets up alternative encoded bit streams for each segment of data and selects the alternative that would produce the bit rate closest to a predetermined target bit rate for transmission. Belt loops at the ends of the arms are adapted to receive a gait belt. The receptacle is shaped to receive a circuit component and forms a waveguide. Heat generated by the electrical component is propagated via the metal cover to the insertion portion of a first cover member. After developing and removing the non-polymerized portion of the coating composition, a tapered waveguide is formed on the substrate.
