Which type of gripper is often powered pneumatically?

The correct choice is 2 point curvilinear gripper, as these grippers are specifically designed to conform to the shape of the object being grasped, allowing for a secure grip on irregularly shaped items. Pneumatic actuation is often utilized in these grippers due to its ability to provide a strong closing force and to enable smooth and controlled movements. Pneumatic systems are advantageous because they allow for rapid actuation and fine control when handling various objects, especially in automated environments.

While the other types of grippers—like the 2 point parallel, 3 point parallel, and rotary gripper—can also be utilized in robotics, they typically use other means of actuation, such as electric motors or mechanical linkages. Pneumatic systems are best suited for tasks that require high speed and efficiency, which makes the 2 point curvilinear gripper an excellent application of pneumatic technology for gripping diverse and complex shapes.
