Haptic Human Interfaces for Robotic Telemanipulation

This paper proposes that there are ultimately only two topical tactile feedback generation modalities for haptic human interfaces which allow the human operator to handle either (i) temporary VR-based material replicas of the local geometric and/or force profile at the contact areas of an unlimited set of generic objects that could virtually be handled during the manipulation, or (ii) permanent material replicas of a limited set of typical objects. Examples of tactile human interfaces developed by the authors for telerobotic blind tactile exploration of objects, for telerobotic hapto-visual stylus-style tool manipulation are presented to illustrate the proposed approach. A NN architecture allowing for the modelling of the elastic properties of 3D objects from experimental tactile and range imaging data is also presented.
