Differences between linear and rotary actuators:
| Linear Actuator | Rotary Actuator |
|---|---|
| A linear actuator produces linear (straight-line) motion. | A rotary actuator produces rotational (circular) motion. |
| It is used for pushing or pulling movements. | It is used for rotating components of a robot. |
| Example: Used in robotic systems such as pistons to move parts in a straight line. | Example: Used in motors to rotate robot wheels or joints. |
