Transparent grippers for robot vision
Proceedings of IEEE International Conference on Robotics and Automation, 2002While existing grippers execute manipulation tasks, they occlude parts of the objects they grasp as well as parts of the workspace from vision sensors. We present the concept of a transparent gripper that enables vision sensors to image an object without occlusion while it is being manipulated. The physics of refraction, total internal reflection, lens

1989
A unique kinematic gripper, based upon a design by Chase et al (1), has been constructed and commissioned in the laboratories of Queen’s Mechanical Engineering. The gripper is part of the robotic equipment at Queen’s Mechanical Engineering and is used in the development of end effector sensors (2,3 and 4).

Goals of robot gripper mechanics
Mechanism and Machine Theory, 1987Abstract This paper is devoted to the methods of computation and analysis of equilibrium positions of the object in the robot gripping device, assuming that the contact between the object and gripper is maintained in a finite number of points. Problems of construction of computation models which make it possible to determine the reliability of ...

Force Sensitive Robotic Gripper
2016Industrial robotic application of gripping unknown objects with two-finger gripper is a challenging task. A traditional grasp model does not fit the requirement of gripping unknown objects, as application of too much gripping force damages and deform the object; while small force results in slipping of the object.

Intelligent Robotic Gripper Control Strategy
Advanced Materials Research, 2013Although, on-off control robot gripper is widely employed in pick-and-place operations, it can not be applied in fragile or soft objects handling. Here, an intelligent gripper is designed with embedded distributed control structure for overcoming the uncertainty of grasped object mass and soft/hard features.

Distributed Control Intelligent Robotic Gripper
Applied Mechanics and Materials, 2013An intelligent gripper is designed with embedded distributed control structure for overcoming the uncertainty of grasped object mass and soft/hard features. An efficient model-free intelligent fuzzy sliding mode control strategy is employed to design the position and force controllers of gripper, respectively.

Intelligent Optically Powered Robot Gripper
SPIE Proceedings, 1989In the paper an intelligent optically powered robot gripper equipped with optical fiber sensors is proposed. The gripper's sensor system includes single sensor modules C an optical fiber slip sensor and an optical fiber colour sensor ) and systems of sensors (a 3-D optical fiber proximity sensing system, an optical fiber tactile matrix for tactile ...

Closed structure soft robotic gripper
2018 IEEE International Conference on Soft Robotics (RoboSoft), 2018This work describes a new kind of soft gripper. Inspiration on nature is usual in Soft Robotics device creation. In this case, the inspiration came from a sea lamprey in order to create a closed structure soft robotic gripper. Usually the grippers have one or more soft actuators that act like fingers.

A Controlled Impedance Robot Gripper
AT&T Technical Journal, 1985The design of robot grippers has traditionally involved pneumatics or gear reduction electric drives that do not allow for the control of the stiffness of the mechanism. The manipulation of fragile objects such as eggs or light bulbs requires the gripper to be able to close on the object with minimal impact forces, and yet maintain a static grip force ...
