What kind of assembly does the base bracket and mechanical arm of an automobile belong to?

Mechanical structure. Mechanical arm refers to a complex system with high precision, multi-input and multi-output, high nonlinearity and strong coupling. Because of its unique operation flexibility, it is widely used in industrial assembly, safety and explosion protection. The installation of automobile underframe and mechanical arm belongs to mechanical structure assembly, and the mechanical arm is a complex system with uncertainties such as parameter perturbation, external interference and unmodeled dynamics. Therefore, the modeling model of the manipulator is also uncertain. For different tasks, it is necessary to plan the trajectory of the joint space of the manipulator to form the end pose in cascade.
