Researchers at Pohang University of Science and Technology (POSTECH) have developed a robotic teleoperation system aimed at improving safety and precision in industrial environments such as steel production facilities. The work, conducted by Professor Keehoon Kim and Ph.D. candidate Jaehyun Park from the Department of Mechanical Engineering, introduces two new haptic devices that enable remote robot control with enhanced tactile feedback. The findings have been published in the journal IEEE Transactions on Industrial Informatics.
The system comprises two devices: POstick-KF, which provides kinesthetic feedback by replicating the force dynamics encountered by robots during tasks like pushing or pulling; and POstick-VF, which offers visuo-tactile feedback for broader operational contexts. Both devices are designed to resemble actual tools in size and shape, supporting intuitive use and reducing the learning curve for operators.
In simulation trials, users operating the POSTECH devices demonstrated improved manipulation accuracy and a decrease in collisions with obstacles when compared to standard haptic technologies. The POstick-VF device, in particular, was associated with notable improvements in operator proficiency over repeated use.
The technology also features digital twin integration, allowing users to simulate robotic tasks in virtual environments, and utilizes augmented reality to enhance focus and engagement during operation.
According to the researchers, the system is intended to support safer execution of tasks that still require human dexterity, despite ongoing automation efforts in high-risk industrial settings.
