What is true about the finger movement of a 2-point parallel gripper?

• A. They move in a curved path
• B. They move in a straight line
• C. They rotate to grasp objects
• D. They can expand and contract

Answer: (B)

In the context of a 2-point parallel gripper, the movement of the fingers is specifically designed to move in a straight line. This type of gripper features two fingers that open and close parallel to each other as they approach and grasp an object. The straight-line motion is essential for achieving a consistent and reliable grip on various parts, ensuring that the gripping action is efficient and predictable. The parallel design allows the gripper to maintain a uniform distance between its fingers as they close, which helps in aligning with the object being grasped. This movement is crucial in industrial applications where precision and repeatability are key, such as in assembly lines or robotic operations that require handling standardized components. While the other options may describe different types of grippers or movements, they do not apply to the fundamental operation of a 2-point parallel gripper, which is characterized by its linear and parallel movement.
