Bio-Inspired Tendon-Driven Finger Design With Isomorphic Ligamentous Joint

IEEE Access, 2020
This paper suggests a novel type of bio-inspired finger design in that the joints that compose the finger mimic the features of human finger joints. They have isomorphic structures but different movements, further, there is no friction between bones in ...
