Outline of Final Research Achievements

For cooperative object transportation by multiple mobile robots, the leader-follower type cooperation has been enthusiastically studied so far. However, in the leader-follower type cooperation, follower robots plan their biped gaits based on the forces generated at their hands after a leader robot moves. Therefore, in the cooperation among biped robots, the time-lag between leader and follower robots may cause fall down of biped robots. Therefore, symmetry type cooperation has been developed in this project, in which every robots synchronously move. Dynamic simulation results show that when the object transportation seed is fast, the leader-follower type cooperation becomes unstable (some of robots fall), while the symmetry-type cooperation maintains stability. The proposed symmetry type cooperation was also verified by performing experiments using two real humanoid robots.
