Which robot system is used to convert stored energy into motion?

• A. Power
• B. Structural
• C. Electrical
• D. Computing

Answer: (A)

The main idea is how energy stored in a robot is turned into motion. That happens through the power system. It houses the energy source (like a battery) and the electronics that convert that stored energy into usable electrical energy to drive actuators. Those actuators—motors, hydraulic, or pneumatic components—transform electrical energy into mechanical energy, producing torque and movement at the joints. So motion comes from the power system’s ability to convert stored energy into kinetic energy via the actuators.

The structural system is just the frame and support; it doesn’t create motion. The electrical system handles power distribution and signals, but the actual conversion of stored energy into motion occurs in the power/drive portion through the actuators. The computing system processes information to decide what to do, but it doesn’t directly convert stored energy into motion.
