Abstract

A behavior planning method is presented for reconfigurable modular robots with coherent structure using a randomized planning. Coherent structure is introduced to cope with difficulty in planning of many degrees of freedom, in terms of control system and robot configuration. This is realized by a phase synchronization mechanism together with symmetric robot configuration, which enables the robot to generate various coherent dynamic motions. The parameters of control systems are explored using a randomized planning method called rapidly exploring random trees (RRTs). The RRT planner has an advantage of simple implementation as well as possibility of integrating differential constraints. The dynamic robot motion is thus planned and preliminary simulation results are shown to demonstrate the proposed planning scheme can generate appropriate behaviors according to environments.
