A motion planning method for a self-reconfigurable modular robot

Abstract
This paper addresses motion planning of a homoge- neous modular robotic system. The modules have self- reconfiguration capability so that a group of the modules can construct a robotic structure. Motion planning for self- reconfiguration is a kind of computationally difficult prob- lem because of many combinatorial possibilities of modu- lar configuration and the restricted degrees of freedom of the module; only two rotation axes per module. We will show a motion planning method for a class of multi-module structures. It is based on global planning and local motion scheme selection that is effective to solve the complicated planning problem.
