They determine the reach and range of motion of the arm. 4. **Actuators**: Devices that convert energy into mechanical motion, driving the movement of the joints. Common types include electric motors, hydraulic cylinders, and pneumatic actuators. 5. **End Effector**: The tool or device attached to the end of the arm, designed to interact with the environment. It can be a gripper, welding torch, suction cup, or any other tool depending on the task. 6. **Sensors**: Devices that provide feedback to the control system about the arm's position, speed, and environment. Common sensors include encoders, force sensors, and vision systems. 7. **Control System**: The brain of the robotic arm, which processes input from sensors and sends commands to actuators. It ensures precise movement and coordination of the arm's components. 8. **Power Supply**: Provides the necessary energy to operate the actuators and control system. It can be electrical, hydraulic, or pneumatic, depending on the design. 9. **Cables and Wiring**: Connects the control system to the actuators and sensors, transmitting power and signals throughout the arm. These components work together to perform tasks with precision and flexibility, mimicking the movements of a human arm.
