Study on grasping a branch of a tree by tendons and digits imitating hind limbs of birds and stabilizing attitude

Abstract

Researches on various bird type flight robots have attracted attentions. However, there are few researches on takeoff and landing. Birds have excellent legs and sense of balance that can stay even on unstable tree branches and electric wires, and they can stay on branches energy-efficiently. Mechanically imitating the landing function of these birds is very important for realizing the autonomous bird-like robots. In this research, we develop grasping mechanism imitating the structure of legs of birds.
