Motion error analysis of a shield machine tool-changing robot based on a screw-vector method

HIGHLIGHTS

• who: Wenxue Qian from the SchoolNortheastern University have published the paper: Motion error analysis of a shield machine tool-changing robot based on a screw-vector method, in the Journal: Scientific Reports Scientific Reports
• what: The error model proposed in this study is used to select multiple groups of specific joint variable values for numerical calculation, and the comparison diagram of position error is obtained, as shown in Fig 17. In this study, a new modular tool-changing robot is designed and analysed in structural design, working principle, kinematics, and various types of error modelling . . .
