Abstract
A three-dimensional universal unit for movable structures includes first and second coupling members. Each coupling member includes two opposing side surface parts, an end face part connected to form a right angle with one end face of each side surface part, a coupling/uncoupling device provided on the two side surface parts and end surface part of the first coupling member and operating independently, a permanent magnet provided on the two side surface parts and end face part of the second coupling member, and a linking part disposed between the two side surface parts of each coupling member. The universal unit further includes a linking member that rotatably links the linking parts of the two coupling members and a drive apparatus that rotationally drives the two coupling members relative to the linking member.
