Force Transmissibility Performance of Parallel Manipulators
In this paper, a new force transmission index called the mean force transmission index (MFTI) is proposed, and the force transmissibility analysis procedure is established for parallel manipulators. The MFTI is an extended definition of the force transmission index (FTI) introduced by the authors previously. It is shown that the FTI is a function of the input velocity ratio (IVR) for a multi-DO...
متن کاملRobust Hybrid Motion Force Control Algorithm for Robot Manipulators
In this paper we present a robust hybrid motion/force controller for rigid robot manipulators. The main contribution of this paper is that the proposed hybrid control system is able to accomplish motion objectives in free directions and force objectives in constrained directions under parametric uncertainty both in robot dynamics and stiffness constraint constant. Also, the given scheme is prov...
متن کاملForce Capabilities of Kinematically Redundant Planar Parallel Manipulators
A methodology to evaluate force capabilities of planar parallel manipulators is presented in this paper. Different from previous approach, kinematic redundancies are handled and proper used to improve force capabilities. Add to actuators wrench parameters normally present in a force optimization problem, kinematic redundancy introduces geometric parameters to be optimized, producing non-linear ...
متن کاملPerformance Evaluation of Redundant Parallel Manipulators Assimilating Motion/Force Transmissibility
Performance evaluation is one of the most important issues in the field of parallel kinematic manipulators (PKMs). As a very important class of PKMs, the redundant PKMs have been studied intensively. However, the performance evaluation of this type of PKMs is still unresolved and a challenging endeavor. In this paper, indices that assimilate motion/force trans...
متن کاملStability analysis of DOF force position control for robot manipulators
In this paper we propose a force position control scheme in a DOF task space which is a generalization of the parallel control scheme in a DOF task space The con troller consists of a PD action on the position loop a PI action on the force loop together with gravity com pensation and feedforward of the desired contact force Kinestatic ltering is not used in the scheme Euler pa rameters are adop...
