A spatial parallel mechanism namely 3-RRS mechanism has been assigned to be attached to the seat of a standard electric wheelchair to prevent the turning over of the handicapped sitting on the wheelchair. The system of the wheelchair and the mechanism is a self-balancing robotic wheelchair and has coped with several road conditions. A stability control system calculates the proper moments on th...

modeling and wrench feasible workspace analysis of a spatial cable suspended robots is presented. a six-cable spatial cable robot is used the same as stewart robots. due to slow motion of the robot we suppose the motion as pseudostatic and kinetostatic modeling is performed. various workspaces are defined and the results of simulation are presented on the basis of various workspaces and applied...

This paper is concerned with the reactive robot system (RRS) which has been introduced as a novel way of approaching human–robot interactions by exploiting the capabilities of haptic interfaces to transfer skills (from the robot to unskilled persons). The RRS was implemented based on two levels of interaction. The first level, which implements the first two stages of the learning process, repre...

The use of satellite remote sensing to estimate coloured dissolved organic matter (CDOM) and identify its potential sources is important for monitoring lake water quality implementing management strategies. In this study, taking Erhai Lake as an example based on MODIS/Aqua images in-situ measured data, we used empirical semi-empirical methods develop algorithms CDOM the fluorescence index (FI37...

Abstract Parallel mechanisms have the advantage of high rigidity, large payload capability, and so on, but positioning accuracy is affected by elastic deflection arising from external load gravity. An approach to improving compensating presented with a 3- R RS parallel mechanism as research object. The implemented introducing springs on moving platform limbs. Taking load, spring force, gravity,...

~Packet scheduling is investigated for the downlink of a multiple-input multiple-output (MIMO) cellular system. The conventional round robin scheduling (RRS) scheme does not utilize the benefits of multiuser environments, although it provides fair channel access chance to users. We propose an antenna-assisted round robin scheduling (AA-RRS) scheme to improve the conventional RRS scheme. The AA-...
