A new family of spatial 3-DOF parallel manipulators with two translational and one rotational DOFs
This paper proposes a new family of spatial 3-DOF (degree of freedom) parallel manipulators with two translational and one rotational DOFs. The manipulators in this family are the variations of the parallel manipulators, which are capable of very high rotational capability, introduced by X.-J. Liu, J. Wang, and G. Pritschow (“A new family of spatial 3-DoF fully parallel manipulators with high r...
متن کاملA New 3-DoF Planar Parallel Manipulator with Unlimited Rotation Capability
Most of three-degree-of-freedom (3-DoF) planar parallel manipulators encountered today have a common disadvantage that is their low rotational capability. However, for many industrial applications, by example in automated assembly systems, cutting machines, simulators, or micro-motion manipulators, a high rotation capability is needed. To overcome such a difficulty, this paper focuses its atten...
متن کاملOn the design of reactionless 3-DOF planar parallel mechanisms
A reactionless machine will not apply reaction forces and moments on the mounting base during motion. This article presents the theory for design of a reactionless planar parallel mechanism. The salient features of this design are: (i) it uses auxiliary parallelograms to locate the center of mass of each leg at the base, (ii) choice of geometric and inertial parameters to satisfy the reactionle...
متن کاملStatic Balancing of Spherical 3-DOF Parallel Mechanisms and Manipulators
The static balancing of spherical three-degree-of-freedom (DoF) parallel mechanisms and manipulators is addressed in this paper. Static balancing is defined here as the set of conditions on mechanism dimensional and inertial parameters which, when satisfied, ensure that the weight of the links does not produce any torque (or force) at the actuators for any configuration of the mechanism, under ...
متن کاملSingularity Analysis of 3-DOF Planar Parallel Mechanisms
This paper presents the results of a systematic study of the singular configurations of 3-DOF planar parallel mechanisms with three identical serial chains. Only prismatic and revolute kinematic pairs are considered. From the point of view of singularity analysis, there are ten different architectures. All of them are examined; the nature of all possible singular configurations are discussed an...
