Controlling grip force by maintaining a constant frictional safety margin to improve robotic grasping

Manipulating soft and fragile objects is a challenging task in robotic grasping. The key challenge for robotic grasping is to exert enough grip force to prevent slipping while being gentle enough to prevent damage to an object. Existing grippers used for processes like automatic harvesting of fruits, either apply excessive grip force leading to...

A Better Grasp on the Asymmetrical Adaptation of Grip Force in Response to Friction Perturbations

Our remarkable sense of touch provides us the feedback that is crucial for successfully manipulating a wide range of objects.<br/>The unconscious synergy between touch and the precision grip is particularly astonishing.<br/>During precision manipulation, humans constantly control their grip force to maintain a safety margin of approximately 25...
