Design and Control of a Quasi-Direct Drive Robotic Gripper for Collision Tolerant Picking At High Speed

Design and Simulation of Double Loop Control for Power Converter Fed Variable Speed DC Drive

Task-driven design of a re-configurable gripper for the robotic picking and handling of limp sheets

The paper deals with an innovative device, enabling multi-point grasp, firm hold and gentle transfer of limp sheets to the sorting buffers, before the feeding of the assembly sections. The design process avails of fully implemented digital mock-ups and runs extended virtual trims, to accomplish the analysis of the prospected fixture dynamical behaviour, as stand-alone device and as integrated e...

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...

Analysis and Design of a Permanent-Magnet Outer-Rotor Synchronous Generator for a Direct-Drive Vertical-Axis Wind Turbine

In Permanent-Magnet Synchronous Generators (PMSGs) the reduction of cogging torque is one of the most important problems in their performance and evaluation. In this paper, at first, a direct-drive vertical-axis wind turbine is chosen. According to its nominal value operational point, necessary parameters for the generator is extracted. Due to an analytical method, four generators with differen...

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...
