The multi-axis robotic arm assembly 2 includes a three-axis robotic arm assembly fixedly installed at the top center of the rotating platform 17. The three-axis robotic arm assembly and the bottom rotating platform assembly 1 form a four-sided swing arm assembly. An electric gripper 28 is provided at the end of the three-axis robotic arm assembly away from the bottom rotating platform assembly 1.
