Robot Path Planning with Avoiding Obstacles in Known Environment Using Free Segments and Turning Points Algorithm

Abstract EN

Currently, the path planning problem is one of the most researched topics in autonomous robotics.

That is why finding a safe path in a cluttered environment for a mobile robot is an important requirement for the success of any such mobile robot project.

In this work, a developed algorithm based on free segments and a turning point strategy for solving the problem of robot path planning in a static environment is presented.

The aim of the turning point approach is to search a safe path for the mobile robot, to make the robot moving from a starting position to a destination position without hitting obstacles.

This proposed algorithm handles two different objectives which are the path safety and the path length.

In addition, a robust control law which is called sliding mode control is proposed to control the stabilization of an autonomous mobile robot to track a desired trajectory.

Finally, simulation results show that the developed approach is a good alternative to obtain the adequate path and demonstrate the efficiency of the proposed control law for robust tracking of the mobile robot.
