This paper presents three trajectory tracking control strategies for unicycle-type robots based on a leader-followers scheme. The leader robot converges asymptotically to a smooth trajectory. while the follower robots form an undirected open-chain configuration at the same time. It is also shown that the orientation angles of all the robots converge to the same value. https://www.itsmajorlook.com/top-deal-Dallas-Cowboys-logo-Fan-Decals-3-75-x-5-p32366-top-mega/
