At Carnegie Mellon University in the United States, research has been conducted to apply artificial intelligence technology to object manipulation by robot, and at the of core of our technology is the concept of "reproducing tactile sensations based on camera imaging” which was conceived in the course of this research. By mounting this technology on the fingertips of a robot hand, it becomes possible for robots to perceive tactile sensations (distribution of force and slippage, etc.), and this, in turn, makes it possible to control objects with a robot as if a human were using their palm to handle objects. By applying these high-performance, economical, practical, and safe vision-based tactile sensor to robot systems, the aim is to automate the pick-and-place process in, but not limited to, the food industry, which is highly dependent on human workers, and thereby reduce the need for human labor.
