About
Power, in the physics sense, is the rate at which energy is transferred or converted over time, measured in watts (joules per second). In robotics and AI, power considerations permeate nearly every system layer: actuators must deliver sufficient mechanical power for locomotion and manipulation, onboard batteries and energy harvesters must supply reliable electrical power, and circuits must operate within tight power budgets to extend operational lifetime. Engineers balance peak power demands—such as a robot jumping or a drone hovering—against average consumption, efficiency losses, and thermal limits. Power also governs the feasibility of untethered, miniature, or wearable systems, where harvesting energy from motion, fluid flow, or electromagnetic sources can replace or supplement batteries. In exoskeletons, delivering the right power at the right moment enables physical assistance without overwhelming the user. In microrobotics, ultralow-power electronics and novel nanogenerators make autonomous operation possible at tiny scales. Understanding power constraints is therefore fundamental to designing robots that are capable, efficient, and practically deployable in real-world environments.
