Book excerpt: "Leader-follower formation control of mobile robots has been investigated by many researchers in the robotics community to control multi-robot systems. This control method can coordinate a team of unmanned vehicles by manoeuvering each robot to maintain its desired position with respect to the leader of the formation. The leader-follower control strategy can also be applied to implement human-follower behaviours on mobile robots. In this thesis, a leader-follower controller was developed for the Micro-Hydraulic Toolkit (MHT), a quadruped wheel-legged robot designed by Defence Research and Development Canada (DRDC) at the Suffield Research Centre. Previously, a velocity-based inverse kinematics controller was designed and implemented on the vehicle to control its posture. However, since the MHT does not have a steering mechanism for its wheels, this controller is unable to execute turning manoeuvres with the robot. Therefore, a separate controller was developed in order to steer the MHT to achieve leader-follower formation control. The purpose of the leader-follower controller is to compute the desired wheel velocities of the robot to reach and maintain a desired range and bearing with respect to a designated leader. To implement the controller on the physical robot, a vision algorithm was developed to measure the range and bearing of the leader with respect to the MHT using a monocular camera. A wide range of leader-follower scenarios was executed in simulation using a high fidelity physics-based model of the Toolkit and on the physical platform of the MHT to assess the performance of the leader-follower controller. The results of these tests demonstrated that the controller developed is successfully capable of executing leader-follower behaviours with the MHT." --
