What best describes the gripping action of a 2-point parallel gripper?

The gripping action of a 2-point parallel gripper is best characterized by simultaneous operation. This type of gripper features two fingers that move in parallel towards each other when closing, allowing them to grip objects consistently and uniformly from both sides. Because the fingers operate together as a unit—moving at the same time and distance—they create a stable grip on the object being handled. This design is effective for various applications, including picking and placing tasks, where a secure grip is essential to prevent slippage or dropping the item.

In contrast, the other options describe actions that are not typical of a 2-point parallel gripper. Curved movement might apply to other types of grippers that have specific designs for accommodating various shapes, while finger rotation would indicate a gripper that allows for adaptive positioning of the fingers, a feature not inherent to the parallel function. Independent movement refers to mechanisms where gripper fingers can move separately from one another, which is not how a 2-point parallel gripper operates.
