Improving control precision and motion adaptiveness for surgical robot with recurrent neural network

IROS 2017poster

Surgical robot research is driven by the desire of improving surgical outcomes. This paper proposed a Recurrent Neural Network based controller to address two problems: 1) improving control precision, 2) increasing adaptiveness for robot motion (explained in Section I). RNN was adopted in this work…

Measurement of the cable-pulley Coulomb and viscous friction for a cable-driven surgical robotic system

IROS 2015poster

In this paper we present experimentally obtained cable-pulley Coulomb and viscous friction for cable-driven surgical robotic systems including the RAVEN II surgical robotic research platform. In the study of controlling cable-driven systems a simple mathematical model which does not capture physical…
