In a robotic system, which component is directly responsible for executing commands?

In a robotic system, the component that is directly responsible for executing commands is the robot arm. The robot arm consists of various joints and linkages that allow it to move in specific ways to perform tasks. When commands are issued from the controller, they dictate the movements of the robot arm, which translates those electrical signals into mechanical actions.

The robot arm is often equipped with precision motors and actuators that facilitate these movements with high accuracy, allowing the robot to interact with its environment or manipulate objects as needed. In essence, the arm acts as the physical executor of the programmed instructions, making it the key component that translates digital commands into tangible actions.

Understanding the role of the robot arm is crucial in designing and programming robotic systems. While the controller sends the commands and the end effector performs the primary task, it is the arm that physically moves and positions the end effector to accomplish those tasks. The power supply, on the other hand, provides the necessary energy for the whole system to operate, but it does not execute commands itself; rather, it supports the operation of the other components.
