Casting and Winding Manipulation with Hyper-Flexible Manipulator

Abstract

Non-elastic hyper-flexible elements like tethers and ropes will have various possibilities of unconventional manipulations. In this paper, casting and winding manipulation of hyperflexible manipulators (HFM) is proposed. The HFM is modeled as an underactuated multi-link system connected by non-elastic passive joints, and simulation results with dynamic parameters heuristically determined corresponding to the experimental results show the validity of the proposed non-elastic model. The simulation results also correspond to the experimental ones with actuation at the base joint. Observations on the simulation results is derived to reveal a better casting actuation to succeed in winding to an object. Then, single swing actuation for winding is proposed and verified in simulations
