Abstract : "This paper presents an adaptive distributed fault-tolerant formation control for multi-robot systems. Both
the kinematics and dynamics of differential wheeled mobile robots are considered. In particular, the problem caused
by actuator faults is investigated. Based on dynamic surface control techniques, adaptive formation controllers can
be obtained under a directed communication network. The closed-loop stability is guaranteed by using Lyapunov
stability analysis such that all followers can exponentially converge to a leader-follower formation pattern. Simulation
and experimental results illustrate that the desired formation pattern can be preserved for a group of wheeled
robots subject to unknown uncertainties and actuator faults."
