Self-Motions of General 3-RPR Planar Parallel Robots
This paper studies the kinematic geometry of general 3-RPR planar parallel robots with actuated base joints. These robots, while largely overlooked, have simple direct kinematics and large singularity-free workspace. Furthermore, their kinematic geometry is the same as that of a newly developed parallel robot with SCARA-type motions. Starting from the direct and inverse kinematic model, the exp...
متن کاملPlanar Parallel 3-rpr Manipulator
This paper describes the design, construction, and control of a planar three degree-of-freedom (dof) inparallel-actuated manipulator at Ohio University. The actuators are three pneumatic cylinders. Using real-time closed-loop feedback control for each actuator length independently, we develop inverse pose and resolved-rate control for this manipulator. The objective of this work is to implement...
متن کاملChanging Assembly Modes without Passing Parallel Singularities in Non-Cuspidal 3-RPR Planar Parallel Robots
This paper demonstrates that any general 3-DOF three-legged planar parallel robot with extensible legs can change assembly modes without passing through parallel singularities (configurations where the mobile platform loses its stiffness). While the results are purely theoretical, this paper questions the very definition of parallel singularities.
متن کاملSensitivity Analysis of 3-rpr Planar Parallel Manipulators
ABSTRACT This paper deals with the sensitivity analysis of 3-RPR planar parallel manipulators (PPMs). First, the sensitivity coefficients of the pose of the manipulator moving platform to variations in the geometric parameters and in the actuated variables are expressed algebraically. Moreover, two aggregate sensitivity indices are determined, one related to the orientation of the manipulator m...
متن کاملNon-Singular Assembly-mode Changing Motions for 3-RPR Parallel Manipulators
When moving from one arbitrary location at another, a parallel manipulator may change its assembly-mode without crossing a singularity. Because the non-singular change of assembly-mode cannot be simply detected, the actual assembly-mode during motion is difficult to track. This paper proposes a global explanatory approach to help better understand non-singular assembly-mode changing motions for...
