1. The main body
The main machinery is the base and the implementation of the mechanism, including the arm, arm, wrist and hand, constitute a multi-degree of freedom of mechanical system.Industrial robots have 6 degrees of freedom or more and the wrist usually has 1 to 3 degrees of freedom of movement.
2. Drive system
The drive system of industrial robot is divided into hydraulic, pneumatic and electric three categories according to the power source.According to the needs of the three examples can also be combined and compound drive system.Or through the synchronous belt, gear train, gear and other mechanical transmission mechanism to drive indirectly.The drive system has power device and transmission mechanism, which is used to implement the corresponding action of the mechanism. Each of the three basic drive systems has its own characteristics. Now the mainstream is the electric drive system.
3. Control system
The robot control system is the brain of the robot and the main factor that determines the function and function of the robot.The control system is in accordance with the input of the program to drive the system and the implementation of the agency to recover the command signal, and control.The main task of industrial robot control technology is to control the range of motion, posture and trajectory of industrial robot in the working space, and the time of action.It has the characteristics of simple programming, software menu manipulation, friendly man-machine interaction interface, online operation prompt and easy to use.
4. Perception system
It is composed of an internal sensor module and an external sensor module to obtain meaningful information about the state of the internal and external environment.
Internal sensors: sensors used to detect the state of the robot itself (such as the Angle between the arms), mostly sensors for detecting position and Angle.Specific: position sensor, position sensor, Angle sensor and so on.
External sensors: sensors used to detect the robot’s environment (such as the detection of objects, the distance from objects) and conditions (such as detection of whether the grabbed objects fall).Specific distance sensors, visual sensors, force sensors and so on.
The use of intelligent sensing systems improves the standards of mobility, practicality and intelligence of robots. Human perceptual systems are robotically dexterous with respect to information from the outside world. However, for some privileged information, sensors are more effective than human systems.
5. End-effector
End-effector A part attached to a joint of a manipulator, typically used to grasp objects, connect with other mechanisms, and perform the required task.Industrial robots generally do not design or sell end-effectors. In most cases, they provide a simple gripper.The end-effector is usually mounted on the robot’s 6-axis flange to complete tasks in a given environment, such as welding, painting, gluing, and part handling, which are tasks that need to be completed by industrial robots.
