How do robotics cognitive systems work?

• A. Perception via sensors, action via actuators
• B. Perception via databases, action via screens
• C. Perception via displays, action via sensors
• D. Perception via actuators, action via cameras

Answer: (A)

In robotics cognitive systems, perception comes from sensors that gather information about the environment, turning real-world input into data the system can reason with. Action is produced by actuators, the motors and other devices that translate decisions into physical movement or manipulation of objects. This pairing—perception via sensors and action via actuators—is what enables a robot to sense what’s around it and then do something about it. The other options mix up where sensing comes from or what can produce movement: databases or screens aren’t real-time perception or physical output, displays are outputs, and sensors are inputs, not endpoints for action. Similarly, actuators are for movement, not perception, and cameras are sensors rather than the means to act.
