Robinson sold two of these rides – Astrowheel, which operated at the former Six Flags Astroworld in Houston, Texas, and Galaxy, which operated at Six Flags Magic Mountain in Valencia, California. Both were manufactured by Astron International Corporation. Astrowheel was part of the original lineup of rides when Astroworld opened in 1968; it was removed in 1981 to make way for the Warp 10 ride. Astrowheel had an eight-spoked spider at the end of each arm, and each tip had a separate car for eight cars in total on each end. In contrast, Galaxy had double the capacity with a four-spoked spider at the end of each arm; each tip bore an independent four-spoked sub-spider for sixteen cars in total on each end. Like Astrowheel, Galaxy was part of the lineup at Magic Mountain when the park opened in 1971, and was removed in 1980 when Six Flags took over ownership of both parks.
