The 3-rprr Kinematically Redundant Planar Parallel Manipulator
In this work, the 3-RPRR, a new kinematically redundant planar parallel manipulator with six degrees of freedom, is presented. First the manipulator is introduced and its inverse displacement problem discussed. Then, all types of the singularities of the 3-RPRR manipulator are analysed and demonstrated. Thereafter, the reachable and dexterous workspaces are obtained and compared with those of t...

being solved to determine the corresponding required joint values, 8(t;). A kinematically redundant manipulator can, in general, satisfy an end-effector positioning constraint, x(t;), with an infinite family of joint values satisfying (2). The underlying premise for advocating the use of redundant manipulators for critical applications is that if a joint should fail, then the redundancy of the ...
متن کاملSingularity analysis of a 3-PRRR kinematically redundant planar parallel manipulator
Finding Singular configurations (singularities) is one of the mandatory steps during the design and control of mechanisms. Because, in these configurations, the instantaneous kinematics is locally undetermined that causes serious problems both to static behavior and to motion control of the mechanism. This paper addresses the problem of determining singularities of a 3-PRRR kinematically redund...

متن کاملA Family of Kinematically Redundant Planar Parallel Manipulators
Parallel manipulators feature relatively high payload and accuracy capabilities compared to their serial counterparts. However, they suffer from small workspace and low maneuverability. Kinematic redundancy for parallel manipulators can improve both of these characteristics. This paper presents a family of new kinematically redundant planar parallel manipulators with six actuated-joint degrees ...
