Abstract

The aim of this proposal is to study numerically and experimentally whether the kinematic redundancy can be a good alternative for parallel planar manipulators to achieve high accelerations. This is not a trivial question, because this solution means not only that there is more torque available, but also that the inertia of the system has been considerably increased. Different configurations of the redundant manipulator are going to be evaluated numerically through cinematic and dynamic models. Objective metrics are going to be proposed and should be employed to aid the designer to infer if redundancy is a good alternative to improve the dynamic performance of planar manipulators. A simple but yet versatile setup are going to be built in order to evaluate experimentally different configurations. This setup will consist of a planar parallel manipulator driven by three rotational direct drives and three linear guides (driven by motors). The degree-of freedom of the setup are going to be driven by the three rotational direct drives while the redundancy is guarantee by the linear guides. (AU)
