A robotic hand developed by OMRON and the University of Tokyo that repeatedly performs precise insertion

Professor Masatoshi Ishikawa of the University of Tokyo and Omron have developed a robot hand that can perform precision work by groping at a speed of 1,000 times per second. When the ring hits the end of the cylinder and the angle shifts, the robot adjusts its three fingers to restore the shift. This is a high-speed reproduction of the way a human being searches for the right angle to fit a ring using the senses of his or her fingertips. In the past, even with the use of force sensors, it took time to process, and insertion and removal took 1-2 seconds. In the automation of precision assembly, it is difficult to keep the positional accuracy within 10 micrometers, including robots and jigs. If this can be handled by hand or control, the range of precision work will expand. Photo taken on November 27, 2019, credit: Nikkan Kogyo Shimbun / Kyodo News Images
