Yoyo - Robot police detective designed by inventor Dr. Yoyonovich on the sci-fi police comedy HOLMES AND YOYO/ABC/1976. Gregory "Yoyo" Yoyonovich (played by John Schuck) was a not-yet-perfected, 427-pound robot equipped with photographic memory, a stomach trash compactor and a self contained film developing lab. His programming quirks included flipping over when he got near a garage door opener and literally bouncing around the room when someone told him to "hop to it." Yoyo's human partner was Det. Alexander Holmes (Richard B. Shull), an accident-prone Los Angeles police officer.
