| Notes | WANG Wei, XU Yong, WANG Xin, SUN Feng-lei （ Shanghai University of Engineering Science, Shanghai 201620） large working space; parallei robot; inverse kinematics; working space In order to meet the demand of large space automation produetion. An innovative concept of industrial robots which processed large workpieees （such as wing riveting） in large work space was presented. The paper also put forward whole configuration and branched chain configuration of 8-UPS parallel robot. Craftily configurations of branched chain- single degree of freedom kinetic pair ensure the robotss walking function, Based on the inverse kinematics model, the ehanging sit-tion affected by driven bar length was solved. Based on three dimensiQnal search method, MATLAB was used to solve the workspace of parallel mechanism in processing conditions, and based on the adaptability of the height of the processing objects- the workspace influenced by parallel mechanism bar length was analyzed. The study found that the cross-sectional area of th |
