The robot body refers to the mechanical part of an industrial robot, also called the manipulator, which is the operating mechanism of the industrial robot. It refers to the robot's physical form and its own components. The overall robot also consists of other supporting software and equipment. The basic structure of the robot body consists of five parts: 1. Transmission components; 2. Body and locomotion mechanism; 3. Arm; 4. Wrist; 5. Hand.
Robot bodies fall under the category of equipment integration. Based on mechanical structure, robot bodies can be categorized into Cartesian robots, SCARA robots, articulated robots, parallel robots, and others. Different types or industries of robots have different technical requirements. For example, welding robots in the automotive industry require high precision and speed from articulated robot bodies, while palletizing and handling robots have higher load-bearing capacity requirements. SCARA robots, widely used in the electronics industry, have high precision and speed requirements. The global industrial robot market is primarily dominated by articulated industrial robots.
The robot body structure comprises the physical structure and mechanical transmission system, serving as the robot's supporting foundation and execution mechanism. The structural characteristics of the robot body include: 1. The robot body can be simplified as an open kinematic chain where each link is connected end-to-end with open ends. The robot body has poor structural rigidity, which varies with its spatial position. 2. Each link in the robot body has an independent actuator, allowing for independent and flexible movement. Generally, linkage mechanisms have 1-2 driving elements, and the movements between links are mutually constrained. 3. The torque variation of the linkage drive is complex and depends on the position of the actuator.
Robot manufacturers can effectively integrate upstream component suppliers and downstream system integrators. Robot manufacturers are responsible for the production, processing, assembly, and sales of components such as industrial robot supports, arms, and bases, as well as precision reducers and other parts. Application and integration can be implemented by the robot manufacturer itself or outsourced to integrators. Robot manufacturers possess the capability to effectively integrate upstream component suppliers and downstream system integrators.
