A device which produces mechanical motion in a robotics system. Conductor A substance or medium that conducts heat, light, sound, or especially an electric charge. Most electrical conductors, such as wires, are made of copper or gold. Like many metals, copper and gold are very good conductors. A device used to produce a desired change in an object in response to input.
Robots use end-effectors to accomplish a task.
The end effector may be holding a tool, or the end effector itself may be a tool, such as a gripper, welder, or drill. Sensor An input device that sends electrical signals or data to the robot about its position, or the state of the world around it. Stimulus Something that causes a response. In robotics, a stimulus is anything that a sensor can sense. For a touch sensor, a stimulus might be a wall or an object.
