1. Mechanical structure system
From the perspective of mechanical structure, industrial robots are generally divided into tandem robots and parallel robots. The characteristic of a tandem robot is that the movement of one axis will change the coordinate origin of another axis, while the movement of one axis of a parallel robot will not change the coordinate origin of another axis. The early industrial robots all used a series mechanism. A parallel mechanism is defined as a closed-loop mechanism in which a moving platform and a fixed platform are connected by at least two independent motion chains, the mechanism has two or more degrees of freedom, and is driven in parallel.
2. Drive system
A drive system is a device that provides power to a mechanical structural system. According to different power sources, the transmission mode of the drive system is divided into four types: hydraulic, pneumatic, electric and mechanical. Early industrial robots were hydraulically driven. Due to the problems of leakage, noise and instability at low speeds in the hydraulic system, and the bulky and expensive power unit, only large heavy-duty robots, parallel processing robots and some special applications use hydraulically driven industrial robots.
3. Perception system
In addition to the need to perceive the mechanical quantity related to its own working state, such as displacement, speed and force, visual perception technology is an important aspect of industrial robot perception. The visual servo system uses visual information as a feedback signal to control and adjust the position and posture of the robot. Machine vision systems are also widely used in all aspects of quality inspection, workpiece identification, food sorting, and packaging. The perception system consists of an internal sensor module and an external sensor module, and the use of intelligent sensors improves the mobility, adaptability and intelligence level of the robot.
4. Robot-environment interaction system
The robot-environment interaction system is a system that realizes the interconnection and coordination between the robot and the equipment in the external environment. The robot and external equipment are integrated into a functional unit, such as a processing and manufacturing unit, a welding unit, an assembly unit, etc. Of course, it can also be a functional unit that integrates multiple robots to perform complex tasks.
5. Human-computer interaction system
The human-computer interaction system is a device for humans to connect with robots and participate in robot control. For example: the computer's standard terminal, command console, information display board, danger alarm, etc.
6. a control system
The task of the control system is to control the actuator of the robot to complete the specified movements and functions according to the robot's operation instructions and the signals fed back from the sensors. If the robot does not have information feedback features, it is an open-loop control system; With information feedback characteristics, it is a closed-loop control system. According to the control principle, it can be divided into program control system, adaptive control system and artificial intelligence control system. According to the form of control movement, it can be divided into point control and continuous trajectory control.
