[0002] A robotic arm is a complex system with high precision, multiple inputs and multiple outputs, high nonlinearity, and strong coupling. Due to its unique operational flexibility, it has been widely used in industrial assembly, safety and explosion protection, and other fields. Since the robotic arm is a complex system, there are uncertainties such as parameter perturbations, external interference, and unmodeled dynamics, so the modeling model of the robotic arm is also uncertain. For different tasks, it is necessary to plan the motion trajectory of the robotic arm joint space, so as to cascade to form the end position. The main function of the robotic arm used on the workbench is to reach the specified position, take the goods to the workbench, or move the goods on the workbench to the specified position.
