This paper presents an anthropomorphic robot hand called Gifu Hand III, which is a modified version of Gifu Hand II. The Gifu Hand is aimed to be used as a platform of robot hands for robotics research. The Gifu Hand III is improved on the points of backlash of transmission, opposability of the thumb, and mobility space of fingertips. The opposability of(More)
This paper presents the design and characteristics of a five-fingered haptic interface robot named HIRO III. The aim of the development of HIRO III is to provide a high-precision three-directional force at the five human fingertips. HIRO III consists of a 15-degrees-of-freedom (DOF) haptic hand, a 6-DOF interface arm, and a control system. The haptic(More)
This paper presents a newly developed anthropomorphic robot hand called KH Hand type S, which has high potential of dexterous manipulation and displaying hand shape, and its master slave system using the bilateral controller for five-fingers robot hand. The robot hand is improved by reducing the weight, the backlash of transmission, and the friction between(More)
This paper presents the design and control of a newly developed five-fingered haptic interface robot named HIRO II. The developed haptic interface can present force and tactile feeling to the five fingertips of the human hand. Its mechanism consists of a 6 degree of freedom (DOF) arm and a 15 DOF hand. The interface is placed opposite the human hand, which(More)
This paper considers moments due to friction forces on the human fingertip. A computational technique called the friction moment arc method is presented. The method computes the static and/or dynamic friction moment independent of a friction force calculation. In addition, a new finger holder to display friction moment is presented. This device incorporates(More)
This paper presents the design and the characteristics of a new developed five-fingered haptic interface robot named HIRO II. The haptic interface can present force and tactile feeling at the five fingertips of the human hand. It is designed to be completely safe and similar to the human upper limb both in shape and motion ability. Its mechanism consists of(More)
This paper presents a strategy meant to allow anthropomorphic robot hands to grasp objects of unknown shape in imitation of the human grasping reflex. A 10-month-old baby may bend his/her thumb and four fingers in an attempt to grasp an object when it comes in contact with the palm. After grasping it, if the object is attempted to be removed from the baby’s(More)
A virtual robot teaching that consists of human demonstration and motion-intention analysis in a virtual reality environment is an advanced technology of automatic programming for multi-fingered robots. As the type of virtual hand model displayed on-screen, a human-hand model is better than a robot-hand model in terms of teaching time and a stable(More)
