This paper is focused on the study of telerobotic interfaces. The interface devices connect the operator to the remote environment. The aim of these devices is, therefore, to get a design that provides the highest degree of telepresence to the operator. In this paper, first a classification of interfaces is introduced according to the processed information: operator’s commands and feedback remote information. Next, a deep study about stereoscopic vision is introduced by showing the results of experiments that evaluate stereoscopic versus monoscopic images. These results are applied to the ROBTET system, a prototype for live power lines. Finally a description of this implementation is given.
