Capsela was a construction toy brand consisting primarily of gears and motors in spherical plastic capsules that could be connected to form various static or dynamic toys suitable for land or water. The capsules usually have six hollow octagonal connectors pointing out, where an octagonal sleeve piece bridges between two capsules. The hollow connection pegs on a capsule can have electrical or rotary adapters inside, reaching into the next capsule. There are electric motor capsules, gear capsules, switch capsules, pontoon capsules, and others; there are also battery holders, wheels, propellers, impellers, lights, wires, and other miscellaneous supporting pieces.
Capsela products were originally manufactured by the Mitsubishi Pencil Company. The series was then licensed out to Play Jour and has since been produced by VTech, Kidology, and a number of other subsidiaries. The range seems to have been recently re-released in Japan by Bandai, adding new colours to the basic range of transparent spheres.
In the U.S., the Capsela line was purchased by Educational Insights, a manufacturer of learning toys and educational materials for school classroom, which has discontinued the line.
Capsela products were originally sold in at least four ranges:
In January 1987, Access Software announced The Robotic Workshop, a kit designed for home computers that used a range of Capsela parts. The kit included over 50 Capsela parts, including two motors, gears, wheels, and sensors. The kit also included an electronic control unit that plugged into the user port of a Commodore 64, an instruction manual with 50 tutorial projects, and special programming software on a floppy disk. It was later released for Apple, Atari, and IBM computers.
Capsela is used in school science technology classes, and to promote technical careers in engineering, robotics and mechatronics to lower high school students, sometimes specifically targeting girls.
