Answer: Mechanical system, drive system, control system, perception system, human-computer interaction system (some robots have it).
Answer analysis: The main components of all robot systems can usually be summarized as follows:
1. Mechanical system
Definition: The mechanical system is the basis for the robot to perform physical tasks, including the body, arm, wrist, end effector and possible walking mechanism.
Function: The mechanical system enables the robot to complete various complex operation tasks through the coordinated movement of joints and connecting rods.
Components:
Body: The main part of the robot, carrying other parts.
Arm: The part that connects the body and wrist, providing a range of motion.
Wrist: The part that connects the arm and the end effector, which is flexible and can adjust the posture of the end effector.
End effector: A component directly mounted on the wrist, used to perform specific tasks, such as grasping, spraying, welding, etc.
Walking mechanism (some robots have it): enables the robot to move on the ground and expand its working range.
2. Drive system
Definition: The drive system is a device that provides power for the mechanical system. It is responsible for converting electrical energy, hydraulic energy or pneumatic energy into mechanical energy to drive the robot to move.
Classification: According to the different drive sources, the drive system can be divided into three types: electrical drive, hydraulic drive and pneumatic drive, as well as a comprehensive system that combines them.
Function: Provide the necessary power for each joint and component of the robot so that it can move according to the predetermined trajectory and speed.
3. Control system
Definition: The control system is the command center of the robot, responsible for receiving instructions, processing information and sending control signals to achieve precise control of the robot's movement.
Composition: It is mainly composed of computer hardware and control software. The software part includes human-computer interaction system and control algorithm.
Function: According to the robot's operation instruction program and the signal fed back from the sensor, the robot's actuator is controlled to complete the specified movement and function.
4. Perception system
Definition: The perception system consists of internal sensors and external sensors, which are used to obtain information about the robot's internal and external environment.
Function: The perception system can detect the robot's motion position, state, and state variables of the surrounding environment (such as distance, proximity, and contact), and feed this information back to the control system so that the robot can respond appropriately.
Components:
Internal sensors: such as encoders, gyroscopes, etc., used to detect state variables inside the robot.
External sensors: such as cameras, lidar, ultrasonic sensors, etc., used to detect environmental information outside the robot.
5. Human-computer interaction system (some robots have)
Definition: The human-computer interaction system is an interface for operators to interact with robots, allowing operators to send instructions to robots, monitor robot status, and receive feedback from robots.
Function: Improve the ease of use and flexibility of robots, so that operators can more conveniently control robots to complete tasks.
In summary, the main components of the robot system include mechanical systems, drive systems, control systems, perception systems, and human-computer interaction systems (some robots have). These parts work together to enable robots to complete various complex tasks.
