چکیده
In this paper the design of a new DOF RPRS parallel manipulator has been proposed Di erent from the conventional Stewart Gough platform manipulator which has six extensible legs the RPRS parallel manipula tor employs three identical RPRS legs to support the mov ing platform Consequently it possesses a compromised per formance e g workspace accuracy and sti ness between a serial robot and a six legged fully parallel manipulator Since all the joint axes excluding the three spherical joints at the leg ends are parallel to each other and perpendicular to the base plane the RPRS parallel manipulator presents a promising platform structure with simple kinematics A two dimensional projection approach is proposed for the dis placement and singularity analysis For rapid deployment the modular design methodology is employed which is able to reduce the complexity of the overall design problem to a manageable level

متن کاملInverse dynamics and trajectory tracking control of a new six degrees of freedom spatial 3-RPRS parallel manipulator
This paper presents the complete dynamic model of a new six degrees of freedom (DOF) spatial 3-RPRS parallel manipulator. The geometry parameters of the manipulator are optimized for a given constant orientation workspace. Further, a robust task-space trajectory tracking control is also designed for the manipulator along with a nonlinear disturbance observer. To demonstrate the efficacy and sho...
متن کاملInterval Analysis of Controllable Workspace for Cable Robots
Workspace analysis is one of the most important issues in the robotic parallel manipulator design. However, the unidirectional constraint imposed by cables causes this analysis more challenging in the cabledriven redundant parallel manipulators. Controllable workspace is one of the general workspace in the cabledriven redundant parallel manipulators due to the dependency on geometry parameter...
متن کاملAn Efficient Algorithm for Workspace Generation of Delta Robot
Dimensional synthesis of a parallel robot may be the initial stage of its design process, which is usually carried out based on a required workspace. Since optimization of the links lengths of the robot for the workspace is usually done, the workspace computation process must be run numerous times. Hence, importance of the efficiency of the algorithm and the CPU time of the workspace computatio...
