What advancements have been made in mechanical grippers?

• A. Increased speed of actuation only.
• B. Reduced payload capacity.
• C. Dual grippers, interchangeable fingers, and sensory feedback to sense the presence of objects and apply specified force.
• D. Only static gripping with no feedback.

Answer: (C)

Advances in mechanical grippers center on versatility and control, not just speed. Having dual grippers enables handling from different directions or even synchronized gripping, which boosts productivity and reliability in complex tasks. Interchangeable fingers let you tailor the fingertip geometry to each object and task—switching between soft, compliant contact for delicate parts and rigid grips for heavier items. Sensory feedback provides information about object presence and the actual grip force, enabling closed-loop control so the gripper can grasp safely and with the exact force needed. This combination of dual grasping capability, adaptable fingers, and force sensing offers a much more capable and flexible solution than simply increasing actuation speed, reducing payload, or sticking with static gripping without feedback.
