Vision-Based Suture Tensile Force Estimation in Robotic Surgery Won-Jo Jung, Kyung-Soo Kwak, and Soo-Chul Lim Abstract :  Compared to laparoscopy, robotics-assisted minimally invasive surgery has the problem of an absence of force feedback, which is important to prevent a breakage of the suture. To overcome this problem, surgeons infer the suture force from their proprioception… 더 보기 »Won-Jo Jung & Kyung-Su Kwak, Journal Paper Accepted (Sensors)

Continuous Image Generation from Low-Update-Rate Images and Physical Sensors through a Conditional GAN for Robot Teleoperation Dae-Kwan Ko ; Dong-Han Lee ; Soo-Chul Lim   Abstract: When a robot is teleoperated, its operator control is based on transmitted images. Network limitations and/or a remote distance usually cause delays or interruptions of the image transmission, which… 더 보기 »Dae-Kwan Ko : Journal Paper Accepted (IEEE Transactions on Industrial Informatics)

Sequential Image-based Attention Network for Inferring Force Estimation without Haptic Sensor Hochul Shin, Hyeon Cho, Dongyi Kim, Dae-kwan Ko, Soo-Chul Lim*  and  Wonjun Hwang*   Humans can approximately infer the force of interaction between objects using only visual information because we have learned it through experiences. Based on this idea, in this paper, we propose… 더 보기 »Journal Paper 게재(IEEE ACCESS) : Sequential Image-based Attention Network for Inferring Force Estimation without Haptic Sensor
