Abstract

A kind of under-actuated self-adaptive mechanical hand was developed in this paper. This mechanical hand consists of three 3-dof under-actuated fingers, and four motors are adopted to drive nine joints. The hand has self-adaptation to targets in different shapes and sizes and it can perform actions, such as folding, unfolding and grasping. In addition, a quasi-statics model of the 3-dof under-actuated finger was established in this paper. The relationship equation between the grasping forces and the driving and damping torques was obtained, and the influence of target size and driving torques on the grasping forces was also discussed. The results of the simulation analysis were shown to verify the correctness of the quasi-statics model.
