The new mechanical hand.

Researchers in the Department of Robotics Engineering at South Koreas Daegu Gyeongbuk Institute of Science and Technology have developed a new type of human-like mechanical hand that, they say, combines the benefits of existing robot hands while eliminating their weaknesses.

A human-like mechanical hand developed by researchers at South Korea's Daegu Gyeongbuk Institute of Science and Technology (DGIST) is designed to be both strong and resilient.

The new design features a crossed flexural hinge (CFH) that can flex or bend in one position and remain rigid in others without creating fiction.

DGIST's Dongwon Yun said, "Our findings show the advantages of both a rigid structure and a compliant structure can be combined, and this will overcome the shortcomings of both."

The robotic hand was found to be 46.7% more shock-absorbent than pin joint-oriented robotic hands; it also is capable of holding objects weighing up to four kilograms (8.8 lbs.).
