Overactuator mechanisms are expected to generate high power with the cooperation of many small actuators. For an example of overactuator mechanisms, we have proposed the network-structure robot which was composed of many multi-jointed links and lineractuators connected with each other with revolute joints. Network-structure modules as the minimum unit of the network-structure were systematically synthesized. And then an arbitrary large scale network-structure could be obtained by connecting the network-structure modules. A new control scheme based on the motions of the representative points on network-structure modules was also proposed. CP-control of an output link of a planar and a spatial network-structure robots could be achieved.
