In this paper, we evaluated the bending property of the designed flexible bionic gripper through an apple grasping experiment. Further, we proposed a three-finger mode to achieve two kinds of motion states: grasping and relaxing, by simulating the movement of an octopus grasping at something. First, a flexible chamber finger was designed to drive the gripper finger to elongate, shorten, and bend, which works through a process of inflating and deflating. Inspired by this, a three-finger flexible bionic robot gripper was designed for apple picking. When an octopus grasps something, the rigidity of its tentacle can change greatly, which allowing for unlimited freedom, agility, and precision. ![]()
