What is an actuator in a robot?
A component that converts energy (often electrical) into physical motion, such as a motor that moves a robot's joint or wheel
What is a servo motor?
A motor that can be precisely controlled to move to a specific position or angle, commonly used for robot joints and steering
What is a degree of freedom (DOF) in robotics?
An independent way a robot part can move, such as rotating around an axis or sliding along one — more degrees of freedom generally means more complex, flexible movement
What is an end effector?
The device at the end of a robotic arm designed to interact with the environment, such as a gripper, welding tool, or suction cup
What is a gear used for in a mechanical system?
Transmitting rotational motion and force between parts, often changing speed, torque, or direction of motion
