Principle of a Simple Robotic Arm
The principle of a simple robotic arm is to utilize a power source such as a motor or cylinder, and convert this power into the movement of the robotic arm through a transmission mechanism, thereby realizing various actions of the robotic arm. The motor is usually a stepper motor or a DC motor, and the speed and direction of the motor are controlled by a controller, thus determining the movement trajectory and speed of the robotic arm. The cylinder is usually a unidirectional or bidirectional cylinder, which uses gas pressure to convert the movement of the robotic arm into mechanical energy, realizing the extension, retraction, lifting, and lowering of the robotic arm.
Composition and Structure of a Simple Robotic Arm
A simple robotic arm typically consists of four parts: a base, an arm body, a wrist, and an actuator. The base serves as the foundation of the robotic arm and usually uses a motor or cylinder as the power source to control the rotation or stationary position of the robotic arm. The arm body is responsible for the extension and retraction of the robotic arm, enabling its forward and backward movement. The wrist is the joint of the robotic arm, controlling its left and right rotation or lifting and lowering. The actuator is responsible for the specific operations of the robotic arm, such as gripping objects, spraying paint, welding, etc.
