Which component handles computation and decision-making in a mechatronics system?

• A. Sensor.
• B. Controller and computation.
• C. Power supply.
• D. Actuator.

Answer: (B)

The computing and decision-making in a mechatronics system is handled by the controller. The controller serves as the system’s brain: it reads signals from sensors, processes that data with control algorithms (such as PID, filtering, or state estimation), decides what action is needed, and sends the appropriate commands to the actuators. This central role ties sensing and actuation together, turning raw measurements into actionable control signals. The power supply simply provides energy to all components and does not perform computation, while sensors only gather information and actuators carry out physical actions. So the controller is the best answer because it performs the necessary processing and decision-making that coordinates the whole system.
