Abstract: Using robot manipulators for high accuracy applications require precise value of the kinematics parameters. Since measurement of kinematics parameters are usually associated with errors and accurate measurement of them is an expensive task, automatic calibration of robot link parameters makes the task of kinematics parameters determination much easier. In this paper a simple and easy ...

objectives: the purpose of this study was to compare scapular kinematics during elevation phase of abduction, flexion, and scapular plane elevation phase between fifteen persons with shoulder impingement syndrome (sis) and thirteen persons without it. methods: values of scapular kinematics include scapular superior and lateral translations, upward rotation, external rotation, and posterior tipp...

the management of road traffic accident and the care of casualties  has undergone many changes in recent years. to provide an uniform and systematic approach the ems, firefighters, red cross, red crescent and other rescuers must be updated to reduce entrapment times, and mortality rates, over better organisation and a methodical approach. the rescuers should not attempt to administer medical fi...

as a robot could be stable statically standing on three or more legs, a six legged walking robot can be highly flexible in movements and perform different missions without dealing with serious kinematic and dynamic problems. an experimental six legged walking robot with 18 degrees of freedom is studied and built in this paper. the kinematic and gait analysis formulations are demonstrated by an e...

A novel n(4-SPS+SP) serial-parallel manipulator (S-PM) formed by n 4-SPS+SP PMs with four degrees of freedom (DOF) connected in series is proposed in this paper. The kinematics , statics and stiffness modeJ of this seriaJ-PM is established. First , the forward kinematics of 4-SPS十SP (spherical jo口比-prismatic joint-revoJute十spherical joint-prismatic joint) PM is d 由er引l口附飞 SPS+SP) S-PM i 比s s 民t...

Background: Lumbar motion analysis is used as a clinical method in the diagnosis and treatment of low back pain (LBP). So far, no studies have shown if manipulating the sacroiliac joint (SIJ) will change spinal kinematics.Objective: The main objectives of this study were to investigate the effects of SIJ manipulation on the lumbar kinematics in subjects with innominate rotation and to compare l...
