Summary: | Underactuated prosthetic hands possess excellent adaptability, yet they often suffer from issues such as complex structure, limited anthropomorphism, and reduced stability. To address these concerns, this paper presents a novel finger with coupled-adaptive functionality, consisting of three joints and two degrees of freedom (DOFs). It exhibits notable anthropomorphism, heightened stability, strong adaptability, and a simplified structure. This finger utilizes a novel coupled-adaptive linkage mechanism, enabling coupled motion in free space and self-adaptive motion while grasping diverse objects. Additionally, a series of simulation analyses have provided evidence that the finger can effectively and stably perform coupled movements and adaptively grasp objects of different shapes and sizes. |
