Purpose – Passively compliant underactuated mechanisms are one way to obtain the gripper which could accommodate to any irregular and sensitive grasping object. The purpose of the underactuation is to use less active inputs than the number of degrees of freedom of the gripper mechanism to drive the open and close motion of the gripper. Another purpose of underaction is to reduce the number of c...

Varieties of robotic grippers are developed with high flexibility and multi-functional approaches. In this paper, the study is an innovative approach of a gripper for handling variable size, shape and weight of unpacked food products i.e. ‘Vacuum Gripper of Robots’ which is working on Bernoulli Principle for generating a high-speed flow between the gripper plate and product surface thereby crea...

This paper proposes a new method for grasping an object positioned in a cluttered workspace. The grasping of an object usually relies on the analysis of its contour in order to determine the contact points for the ngers of the gripper. The planning of the positioning of the real gripper in the workspace at the chosen points is often considered as a separate problem. The method proposed in this ...

The development of universal grippers able to pick up unfamiliar objects of widely varying shapes and surfaces is a very challenging task. Passively compliant underactuated mechanisms are one way to obtain the gripper which could accommodate any irregular and sensitive grasping object. The purpose of the underactuation is to use the power of one actuator to drive the opening and closing motion ...

This paper discusses the design and modeling fundamentals of a multi-degree-of-freedom reconfigurable robotic gripper system (RGS), designed to automate the process of limp material handling, reliably and without distortion, deformation, and/or folding. The reconfigurable gripper design draws upon the authors' previously reported flat surfaced, fixed-dimensions gripper system [1]. The design co...

This abstract outlines current developments of a micro-assembly facility focusing on studies using a three fingered gripper. Individual fingers of the gripper comprise thin fibers ranging in diameter from 7 to 80 μm that are attached to quartz based oscillators and are capable of sensing proximity, contact, and controlling adhesion forces. To optimize gripper finger performance, an electrolytic...

Abstract—This paper presents a design and optimization for a compliant gripper. The gripper is constructed based on the concept of compliant mechanism with flexure hinge. A passive force regulation mechanism is presented to control the grasping force a micro-sized object instead of using a sensor force. The force regulation mechanism is designed using the planar springs. The gripper is expected...

While 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 reeection, lens eeects, dispersion and transmit-tance are a...
