Aiming at the phenomenon of excavator robots easily having accidents in the course of swing

a method is put forward for excavator robots to avoid barriers in this process. By analyzing kinetic characteristic of working device of excavator robot and combining kinematics

kinematics model for robot is established. Laser radar which are installed on both sides of the excavator robot working device are used to identify the operating environment in the process of the excavator robot swing. According to the identified obstacles to solve feasible region

the system will apply the obstacle avoidance algorithm to make the robot avoid obstacles. The experimental results show that the excavator robot prototype can safely avoid obstacles

which verifies the feasibility of the method.
