Design and analysis of a variable-stiffness robotic gripper

Design of a Variable Stiffness Soft Dexterous Gripper

This article presents the design of a variable stiffness, soft, three-fingered dexterous gripper. The gripper uses two designs of McKibben muscles. Extensor muscles that increase in length when pressurized are used to form the fingers of the gripper. Contractor muscles that decrease in length when pressurized are then used to apply forces to the fingers through tendons, which cause flexion and ...

Design and Performance of a Multi-Port Robotic Suction Gripper

This paper presents the mechanical-workings and gripping performance characteristics of a vacuum-based robotic gripper. The gripper uses multiple ports with attached commercial suction cups to grasp objects from a variety of directions using suction power. The valves remain closed until opened by a hinge-based mechanism, in order to eliminate vacuum leakage. The ability for the valves to be act...

‏‎a phonological contrastive analysis of kurdish and english‎‏

deposite the different criticisms on contrastive analysis it has been proved that the results of it(when processed)can be usuful in a tefl environment,specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims. the consonants,vowels,stress and intonation of the twolanguages are described by the same model-ta...

Design fundamentals of a reconfigurable robotic gripper system

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...
