A 2-point curvilinear gripper has 2 fingers jointed from a what?

The correct answer is that a 2-point curvilinear gripper typically operates from a single pivot point. This design means that both fingers of the gripper are connected and move in relation to a common pivot point, allowing them to work in unison to grasp objects effectively. The movement from a single pivot point enables the fingers to adapt to the curvature of the objects being gripped, providing a more versatile and efficient grasp.

In this configuration, when one finger moves, the other finger follows a predetermined path dictated by the position of the pivot point. This characteristic is crucial for curvilinear grippers as it allows them to maintain a consistent angle and pressure while grasping, which is particularly beneficial for uneven or irregularly shaped items.

Understanding the mechanics of this type of gripper helps in applications where precise manipulation of objects is required, as the single pivot design simplifies control and increases the reliability of the gripping action.
