A research team led by Professor Keehoon Kim and Ph.D. candidate Jaehyun Park from POSTECH’s Department of Mechanical Engineering has developed two novel haptic devices to bridge the human-robot gap. Haptic feedback, familiar to many through vibrating smartphones, now finds a crucial industrial role. The team’s devices transmit real-time tactile sensations to the user, enhancing control and awareness while operating robots remotely.

Overview

  • POSTECH researchers, led by Professor Keehoon Kim and Jaehyun Park, developed two haptic devices—POstick-KF and POstick-VF—designed for remote robotic manipulation in hazardous industrial settings.
  • The POstick-KF provides kinesthetic feedback for precise force control, while the POstick-VF combines visual and tactile feedback, enhancing training and usability in larger workspaces.
  • Simulation trials showed these devices improved manipulation accuracy and reduced collisions compared to conventional haptics, with POstick-VF offering notable training benefits over time.
  • The system incorporates digital twin simulations and augmented reality (AR) to allow operators to rehearse tasks virtually and improve their focus during live operations.
  • Published in IEEE Transactions on Industrial Informatics, the research is now supported by POSCO Holdings and positioned for industrial trials aimed at advancing human–robot collaboration.
