Pneumatic actuators

Definition

Pneumatic actuators are devices that convert compressed air energy into mechanical motion, typically used to control or move components in various systems. These actuators leverage the force of air pressure to create linear or rotary motion, making them highly effective in applications requiring rapid movement and force. Their design often incorporates lightweight materials and innovative fabrication techniques, allowing for integration into robotic systems that mimic natural movements.
