WHAT ALL ROBOTS DO Most robots have three things in common First robots often have sensors These are like the eyes and ears of the robot Second robots have computer processors These act like the robot’s brain They allow it to follow instructions or even make decisions on its own Third robots have actuators Actuators are motors that allow the robot to react to its environment For an example of these parts in action imagine a wheeled robot moving around a room With its sensors the robot notices that it is about to run into a wall The robot uses its processor to think about this situation It has been instructed to avoid walls It uses its actuators attached to wheels to turn away from the danger This pattern of behavior is called sense-think-act Robots do each of these steps but not all machines that do these steps are robots An air conditioner can sense with a thermostat think with a computer and act with its cooling system But an air conditioner is not a robot
