چکیده

Aiming to overcome the serious disadvantages of two kinds of under-actuated fingers: coupled finger and self-adaptive finger, this paper proposed a novel grasping mode, called Coupled and Self-Adaptive (COSA) grasping mode, which includes 2 stages: firstly coupled and then self-adaptive grasping. A 2-joint COSA finger with double tendons mechanisms (called COSA-GRS finger), is designed based on the COSA grasping mode. The new finger unit has the advantages of coupled finger and self-adaptive fingers. Using the COSA finger, a humanoid multi-fingered hand can be designed. The new hand will be more similar to human hand in appearance and actions, able to more dexterously and stably grasp different objects than tradition coupled or self-adaptive under-actuated hands.

A Novel Coupled and Self-adaptive Under-actuated Grasping Mode and the COSA-DTS Hand

A novel category of humanoid robotic hands: COSA (Coupled and Self-Adaptive) hand is introduced in this paper. If a hand is called the COSA hand, which means that the fingers of the hand grasps objects with a special COSA grasping mode, which includes two processes, first is a coupled grasping process, then the second is a self-adaptive grasping process. The COSA grasping mode can take many adv...

Topology and Analysis of Three-Phalanx COSA Finger Based on Linkages for Humanoid Robot Hands

The design of a novel linkage three-phalanx finger was proposed in this paper. The finger is based on the concept of COSA (coupling and self-adaptation) and also two-phalanx COSA finger. As a combination of rigid coupled finger and self-adaptive under-actuated finger, the COSA finger has comprehensive grasping ability with human-like motion. Available topology designs were discussed in this pap...

A large amount of e®ort has been devoted to design better under-actuated robot hands. The most widely adopted approaches include rigid coupled hands and self-adaptive hands. The objective of this research is to design a robot ̄nger which combines advantages of both ways and overcomes their disadvantages. The concept of coupling and self-adaptation (COSA) was introduced. A linkage-based two-DOF (...

A Dexterous and Self-adaptive Humanoid Robot Hand: Gesture-Changeable Under-Actuated Hand

A novel concept called gesture-changeable under-actuated (GCUA) function is proposed to improve the dexterities of traditional under-actuated hands and reduce the control difficulties of dexterous hands. Based on the GCUA function, a new humanoid robot hand, GCUA Hand is designed and manufactured. The GCUA Hand can grasp different objects self-adaptively and change its initial gesture dexterous...
