Research of Cooperative Robot for Nursing Tasks

Professor Bing Li


During the past decades, the issue of human-friendly robotic applications has been a mainstream direction for the service robots and assistive robots in both domestic and hospital environments. This presentation will introduce research in our group on the cable-driven serial-parallel robot for the high-payload transferring tasks of patients and the variable stiffness actuator for the safely physical human-robot interaction. Towards the transferring tasks, using intelligent robots is an effective way to help the patients turn over, or transfer the patients between the bed and wheelchair. This requires the nursing robot to have a higher load capability and be safer enough for patients. For the heavy-load transferring robot, this presentation addresses the following issues: the design of high-payload cable-driven manipulator, kinematics and dynamic modeling, motion control and transferring experiments. Considering the robotic applications where robots and humans cooperate, the need for the development of variable stiffness actuator is heightened which is suitable for energy storage, shock resistance and safety in human-robot interaction scenarios. This presentation will also share some thoughts regarding the design of variable stiffness actuator, external force estimation based on current-deflection fusion, and the stiffness/force control for the physical human-robot interaction.
