NEDO, DOUBLE Research and Development Co., Ltd., and the Tokyo Metropolitan College of Industrial Technology have successfully developed a robot hand, "Karakuri," which can grab hold of objects in various shapes stably and gently using an extremely simple control scheme.

Thanks to this new structure, which was engineered to imitate the delicate structure of human hands and fingers, electric components such as sensors or motors, as well as program controls, can be made less complex. Therefore, this structure is expected to reduce the weight of robotic hands, increase durability, lower the risks of failures and incidents, and save power.

The new structure was applied to three kinds of robot hands, "F-hand," "New D-hand," and "Origami hand." These applications are expected to be used in agriculture and logistics, manufacturing, and health fields such as in medical care and food production. In the future, usage is expected to expand to extreme situations such as aerospace and deep sea operations.

DOUBLE Research and Development Co., Ltd., will showcase these three robot hands at "RoboDEX: The 2nd Robot Development & Application Expo," which will be held at Tokyo Big Sight from January 17 to 19.
