In robotics, the arm moving unit usually refers to the part of the robot responsible for moving and manipulating objects, which is what we usually call a "mechanical arm" or "robot arm".
It is a key component in the robot system, which can simulate the movement function of the human arm and perform operations such as grasping, handling, and processing.
The main components of the arm moving unit include:
1. Base: Provides support and stability, and is the fixed part of the entire arm.
2. Joints: Allow the arm to move flexibly at multiple angles. The number and type of joints determine the flexibility and range of motion of the arm. Common joint types include rotational joints and translational joints.
3. Link: Connects the joints and transmits force, allowing the arm to move along a predetermined trajectory.
4. End effector: Used to perform specific tasks, such as grasping, handling, etc. There are many types of end effectors, such as mechanical grippers, suction cups, welding guns, etc., which are selected according to different application requirements.
Working principle of arm mobile unit:
1. Sensor perception: There are many sensors installed on the arm to perceive the surrounding environment and the state of the arm itself, such as the position, shape, color, force, etc. of the object.
2. Data processing and decision-making: The information obtained by the sensor is transmitted to the control system, which processes and analyzes the information by running the preset algorithm and makes corresponding control decisions.
3. Power drive: The control system sends a control signal to the motor, and the motor drives the joint to rotate or translate according to the size and frequency of the signal, thereby driving the entire arm to move.
4. Task execution: Under the precise control of the control system, the arm moves to the specified position and performs specific tasks through the end effector, such as grabbing objects and moving them to a specified location.
Application fields of arm mobile unit:
Arm mobile units are widely used in industrial automation, manufacturing, medical, service robots and other fields. In industrial automation, arm mobile units can perform repetitive, heavy or dangerous work tasks to improve production efficiency and safety.
In the medical field, arm mobile units can be used for delicate operations such as surgical assistance and drug delivery. In service robots, the arm moving unit can realize interaction and collaboration with humans.
In summary, the arm moving unit is an important part of robot technology. By simulating the movement function of human arms, it realizes the precise operation and control of objects.
With the continuous development of technology, the performance and application scope of the arm moving unit will continue to expand and improve.
