Design and Implementation of Mobile Robot Path Planning Based on A-Star Algorithm

With the rapid development of computer technology, more and more mobile robots appear in people’s lives, but they often have the problem of slow search for the optimal path and low work efficiency. In view of the above shortcomings, the path planning of mobile robot is studied in this paper. First, complete the design of the planned path based on the A-star algorithm, and then complete the design and implementation of the drive circuit of the mobile robot’s motion unit, including the motor drive circuit and the steering gear drive circuit. The test results show that in a 50*50 grid, and the obstacle coverage rate is 50%, the tracking speed of the A-star algorithm is as high as 0.17s, and the control error of the motor and the steering gear does not exceed 5 %.
