PROBLEM TO BE SOLVED: To provide a built-up block capable of building up a built-up toy with high degree of freedom in respect of action, control or the like, simple wiring and programming. ;SOLUTION: A drive blocks 46a-c, a power source block 47 and an infrared ray communication block 48 are joined with each other between base blocks 49a, 49b. A power source wire and a network wire of the respective blocks 46a-c, 47, 48 are interconnected through a power source wire and network wire in the base blocks 49a, 49b. An infrared ray communication block 48 gives and receives the control information of the drive blocks 46a-c to and from a remote controller. The drive blocks 46a-c is controlled by binding four network variables of the remote controller with the network variables of the drive blocks 46a-c.;COPYRIGHT: (C)1998,JPO
