Design of parallel-jaw gripper tip surfaces for robust grasping
2017
2017 IEEE International Conference on Robotics and Automation (ICRA)
Preserved Fulltext
Although the shape, texture, and compliance of gripper jaw surfaces affect grasp robustness, almost all commercially available grippers provide a pair of rectangular, planar, rigid jaw surfaces. ...
Parallel-jaw robot grippers can grasp almost any object and are ubiquitous in industry. ...
We are grateful to our colleagues at Stanford for providing the gecko-inspired gripper surface material, in particular Mark Cutkosky, Elliot Hawkes, and Wilson Ruotolo, with special help from Vincent Duchaine ...

IPC-GraspSim models both the dynamics and the deformation of compliant jaw tips to reduce Sim2Real gap for robot grasping. ...
Soft compliant jaw tips are almost universally used with parallel-jaw robot grippers due to their ability to increase contact area and friction between the jaws and the object to be manipulated. ...

The initial resting pose of many industrial parts differs from the orientation desired for assembly. We show that it is possible to align parts during grasping using a standard parallel-jaw gripper. ...
A solution is an arrangement of four gripper point contacts that will align the part in the vertical plane as the jaws close. ...
