Abstract To meet the requirements of large tolerance, high precision, soft capture and reliability space gripper, a three finger end effector is developed. The gripper adopts fingered configuration, which needs to be used together with corresponding adapter. It characterized by stable grip, clamping force, tolerance strong correction ability. A 6-DOF microgravity equivalent device innovatively ...

Liquid Gripper In article number 2100274, Liang Hu, Yen Wei, Jing Liu, and co-workers present a magnetic liquid gripper based on metallic ferrofluid that enables intimate contact with arbitrarily shaped objects then generates strong adhesion force upon solidification, which can be reversibly eliminated by moderate melting. Through coupling the magnetism of switchable to objects, any non-magneti...

A new shape-based object pose estimation for collaborative robot with two-finger gripper has been proposed here. This method uses the smallest enclosing shapes target and takes advantage of symmetrical characteristic to determine gripping direction gripper. First, interesting pick place will be detected segmented. Second, segmented is transformed into its convex form. Next, are approximated bes...

We present the design of a universal gripper based on principle liquid jamming. The phase change behavior mineral oil subjected to cooling is used for adaptive gripping and release objects. enclosed in soft, compliant membrane molded into spherical shape. with easily adapts shape object be picked up. A thermoelectric system designed conductive spreader immersed quickly cool held membrane. Once ...
