چکیده

This paper describes mechanical modeling of soft-fingered grasping and manipulation. Here, we used a simple hand consisting of a pair of 1-DOF rotational fingers with hemispherical soft fingertips to investigate the mechanics of soft-fingered grasping and manipulation. Based on the observations of soft-fingered grasping and manipulation, we propose a parallel distributed model with tangential deformation of hemispherical soft fingertips. We experimentally verified our proposed parallel distributed model. We then show that simulation results based on the parallel distributed model agree with the observations well.

Stable Grasp and Manipulation in 3D Space with 2-Soft-Fingered Robot Hand

Abstract. We report on our newly developed two-fingered robotic hand with soft and thin skin. This hand is basically controlled by a position-based control algorithm. However, it can realize desired grasping force due to the soft skin while maintaining stability of the system. For an experimental validation of this concept, we conducted following the three kinds of manipulation tasks: manipulat...

Grasp analysis of a four-fingered robotic hand based on Matlab simmechanics

The structure of the human hand is a complex design comprising of various bones, joints, tendons, and muscles functioning together in order to produce the desired motion. It becomes a challenging task to develop a robotic hand replicating the capabilities of the human hand. In this paper, the analysis of the four-fingered robotic hand is carried out where the tendon wires and a spring return me...

Hierarchical control method for manipulating/grasping tasks using multi-fingered robot hand

In this paper, we propose a hierarchical control method for manipulation/grasping tasks using multi-fingered robot hands. This method imitates human motion control. Human motion can be divided into two classes, reflex and voluntary movement. Reflex is suppressed by voluntary movement. In the proposed method, a robot hand’s grasping control corresponds to human reflex and manipulation control co...

Development of a Multi-fingered Robot Hand with Softness-changeable Skin Mechanism

This paper develops a multi-fingered robot hand with skin mechanism enabling softness change. We show how the softness of the skin affects grasping and manipulation. Elastic skin provides stable grasping while precise manipulation is lost. Hard skin provides precise manipulation while stability of grasp is lost. We will try to change the softness of the skin according to situation, object, and ...
