Abstract

In order to solve the problems of low success rate and long planning time of mobile robot in complex environment

a mobile robot docking position optimization algorithm is proposed based on environment information preprocessing. Firstly

the workspace of the manipulator is analyzed

and the evaluation criteria of grasping difficulty are obtained. The positions of objects

obstacles and mobile chassis in the environment are simplified as points and projected on the

plane. According to the evaluation criteria of grasping difficulty

the optimized chassis docking position of the mobile robot is obtained. For the obstacle avoidance problem of the manipulator

the rapidly-exploring random trees (RRT) algorithm is used to realize the robot end

connecting rod and obstacle.

Finally

through the simulation and experiments in the motion capture system

it is found that using the parking position optimization algorithm of mobile robot can increase the success rate of grasping objects and the speed of grasping planning .
