The fingers of a 2-point curvilinear gripper are designed to primarily do what?

The fingers of a 2-point curvilinear gripper are primarily designed to grip uneven surfaces. This type of gripper is characterized by its ability to conform to the shape of the object being grasped. The curvature of the fingers allows for better contact and stability when handling objects that are not flat or uniform. By adapting to the contours of various items, the gripper can maintain a secure hold, which is essential for effective manipulation in robotic applications.

In contrast, the other options do not accurately capture the fundamental purpose of a 2-point curvilinear gripper. For example, while rotating around an axis may be a feature of some robotic components, it is not the primary function of this type of gripper. Similarly, movements in a parallel manner or the ability to expand and contract might pertain to other gripper designs but do not reflect the focus of a curvilinear gripper, which is all about adapting to surface variations for improved grip.
