In order to establish high-speed robot senses that are much faster than human senses, we are conducting research and development of information systems and devices that can achieve real-time image processing at 1000 frames/s or greater. As well as integrated algorithms to accelerate sensor information processing, we are also studying new sensing methodologies based on vibration and flow dynamics; they are too fast for humans to sense.

Laparoscopy Forceps with Force Visualization Mechanism

This study proposes a force visualization mechanism using Moire fringe for laparoscopy instruments. The mechanism can display amplitude of a force between the instruments and the internal organs to the user. It consists of an elastic element and two plates printed with stripe patterns and needs not electric elements such as an amplifier and strain gauges. We have developed a forceps with the proposed mechanism and have experimentally verified that it can display amplitude of the grasp force.
