Servo robotic arm is a type of robotic arm that can accurately and automatically control motion. It consists of a driving system, a control system, a mechanical structure, and sensors. Through the coordination of the control system and sensors, precise control of the movement of the robotic arm is achieved.
The working principle of servo robotic arms mainly includes the following aspects:
1. Sensor signal acquisition: Servo robotic arms are often equipped with various sensors, such as position sensors, force sensors, visual sensors, etc., to collect information about the robot itself and its surrounding environment. Sensors can monitor the position, strength, and visual information of the robotic arm in real-time, and transmit this information to the control system for analysis and processing.
2. Control system: The control system is the core part of the servo robotic arm, responsible for collecting and processing signals collected by sensors, and generating control signals for the robotic arm's actions based on pre-set rules and algorithms. A control system generally consists of a computer and corresponding controllers, which can be programmed and control parameters adjusted as needed.
3. Drive system: The drive system is the key to the movement of the robotic arm, which controls the actions of the executing mechanism (such as motors, hydraulic cylinders, etc.), enabling the robotic arm to complete various actions like a human hand. The drive system usually drives the movement of the robotic arm through a motor based on the instructions of the control system, achieving precise control of parameters such as position, speed, and force.
4. Mechanical structure: The mechanical structure is the physical carrier of a servo robotic arm, consisting of various linkages, joints, and end effectors, capable of achieving motion with multiple degrees of freedom. The design and manufacturing of mechanical structures need to consider the working scenario and tasks of the robotic arm, with good stiffness, accuracy, and overload capacity.
Overall, the working principle of a servo robotic arm is to collect information through sensors and transmit it to the control system for analysis and processing. The control system generates driving signals based on rules and algorithms, and the driving system controls the execution mechanism to achieve the movement of the robotic arm. Through continuous feedback and adjustment, servo robotic arms can achieve precise control and automated motion, completing various tasks that require high precision and efficiency.
Servo robotic arms are widely used in industrial production, logistics distribution, medical and health care, scientific research experiments, and other fields. They can replace human labor to complete dangerous, heavy, and repetitive tasks, improve production efficiency and work safety.
