A Mecanum wheel trolley equipped with a robotic arm is proposed,which aims to realize the functions of object grasping and automatic obstacle avoidance.Firstly,the structural design and working principle of the robotic arm and the Mecanum wheel trolley were introduced.Secondly,the functions of the trolley using lidar to perceive the surrounding environment for mapping,using the Gmapping algorithm to avoid obstacles to complete path planning,and the function of the robotic arm to recognize the different colors of the blocks through the depth camera and suc-cessfully sorting are elaborated.Finally,the feasibility and stability of the system are proved through experiments,and the future development trend and application prospects are summarized.
