The purpose of this paper is to present experiment results on the implementation of consensus algorithm on a group of humanoid robots.The experiment in this work is based on some previous works on distributed control of robotic networks and distributed consensus in multi-vehicle cooperative control.According to Ren, a consensus may occur if communication topology between the robots forms a spanning tree.The existence of some shared informations is a necessary condition for this algorithm.Further, a consensus may occur if the topology of communication among the robots forms a spanning tree.However, to apply the algorithm on a group of humanoid robots we need some modification on the original algorithm.A new algorithm is proposed by adding a new damping variable (β) on original algorithm to make a group of humanoid robots move synchronously.The experiment of the new consensus algorithm is tested on two topologies, which are leader-follower and leaderless topology.This research concludes that consensus in a group of humanoid robot can be achieved by inducing damping variable in original equation.
