(The robotic arm is the most widely used and mature type of robot, mainly used in factory automation environments. After decades of development, the technology of the robotic arm has become relatively mature, including kinematics forward and reverse solutions, motion trajectory planning, collision detection algorithms, etc. With the development of collaborative robots, robotic arms have gradually entered people's lives. ROS provides many functional packages for robotic arms, and these functional packages are integrated into a single ROS software - MoveIt!)
