Design and Analysis of a Robotic End-Effector for Automated Hi-Lok Nut Installation

A Robotic End-Effector for Grasping Sacks

This article describes an end-effector and a method for manipulating deformable objects with undefined shapes and geometry such as sacks and bags. The first prototype end-effector, designed for applications in the U.S. Postal Service, comprises two parallel rollers with gripping sur-faces, where the rollers are pushed towards each other. When the end-effector comes onto contact with any portion...

Gravity Robotic End Effector

The ability to easily manipulate objects in a zero gravity environment will play a key role in future space activities. Emphasis will be placed on robotic manipulation. This will serve to increase astronaut safety and utility in addition to several other benefits. It is the aim of this research to develop control laws for the zero gravity robotic end effector designed by engineers at NASA Godda...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

‏‎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...
