This paper deals with the formation and obstacle avoidance of mobile robots in a cluttered environment. By combining an artificial potential field, a leader-follower method is presented to make the multi-robot system keep formation whilst avoiding obstacles. According to the pose and movement conditions of the designated leader, the follower would adjust its position so that the formation control...
In this paper, an intelligent trajectory following and cooperation algorithm is proposed based on the fuzzy approach for a group of mobile robots. The cooperation algorithm adjusts the robots' velocities so they move on their individual trajectories and finish together regardless of the length of each individual trajectory. The fuzzy rules are defined by the kinematic limitation on the robots which...
In this paper, coordination and crash avoidance algorithm between a group of mobile robots is proposed based on the fuzzy control. Fuzzy control is developed to make the robots move in the predefined trajectories that must not collide. All the robots are coordinated so that they finish their trajectories in the same time, regardless of the length of the individual trajectories or the number of crash...
This paper proposes novel formation maintenance strategies for multiple nonholonomic mobile robots based on nonholonomic trajectory tracking techniques and dynamic feedback linearization. It also presents experimental results for formation stability and noise tolerance of the proposed and existing leader-follower based controllers using physical P3AT robots. The research focusses only on the problem...
We develop a systematic approach to synthesize distributed control laws for motion coordination in a group of constant-speed kinematic rigid bodies. Parallel and balanced circular formations of mobile agents moving in a three dimensional space are studied, and provably correct steering laws are presented. The resulting steering laws have simple geometric intuitions which are based on the structure...
