A Decentralized Control Algorithm for Modular Manipulators Using Coupled Nonlinear Dynamics

摘要

A basic decentralized control algorithm for modular manipulators was introduced to achieve robustness against partial failures, a reduced calculation load, and flexibility with regard to configuration and obstacle avoidance. The algorithm uses a coupled nonlinear spring as a model for a manipulator and calculates the shape of the manipulator to balance with the coupled spring. Because encoding using coupled nonlinear dynamics can explain various shapes very simply, we can reduce the complexity of obstacle avoidance and adaptation to partial faults.
