Charles "Robby" Robinson, inventor of Robby's Automatic Wrist Positioner and namesake of the Professional Women's Bowling Association's Robby Award, died April 24 after a brief hospitalization. He was 86. Robinson, a long-time Professional Bowlers Association competitor, received the first of eight patents for bowling products he developed in 1972. His original "Ball Positioner" evolved into a series of wrist supports, gripping aids, liquid skin patch, shoe protectors and a unique four-ball caddy on wheels – all products designed to solve problems faced by the average bowler. He incorporated Robby Products in 1974 and later sold his company to Ebonite International.
