OBSTACLE AVOIDANCE OF A MOBILE ROBOT IN DYNAMIC ENVIRONMENT WITH A NEW NAVIGATION STRATEGY

The motion planning and control problem is a well-known problem in the field of robotics. The objective is to find collision-free trajectories for a robot, in static or dynamic environments containing some obstacles, between a start and a goal configuration. In this context the term control has a broad meaning that includes many different controls, such as low-level motor control, and behaviour control, where behaviour represents many complicated tasks, like obstacle avoidance and goal seeking. This paper describes a method for obstacle avoidance and navigation of mobile Robot in dynamic environment that this mobile robot is called KheperaII. Environment of simulation consists of dynamic and static obstacles and targets. A simulation is done with the help of MATLAB and the KIKS package, representing the results. Results of simulation is compared with potential field and seen that our method is better.
