What is an I/O signal in the context of robotic systems?

In the context of robotic systems, an I/O signal refers specifically to input and output signals used for communication between the robot and other devices, such as sensors, controllers, and actuators. Input signals can come from various sources, such as limit switches or sensors, indicating the status of the environment or the robot itself. Output signals are sent from the robot to other devices to control various functions, including motors, lights, and other external equipment. This bidirectional communication is essential for the robot to operate effectively within its system, allowing it to respond to inputs while performing tasks through outputs.

Understanding I/O signals is crucial for programming and integrating robotic systems into larger automation frameworks, as they are the means through which the robot interacts with its environment. This interplay allows for sophisticated control and automation tasks that are foundational to robotics applications.
