Embodiment Construction

[0026] Figure 1a and 1b Shown by ALDEBARAN ROBOTIC TM Two examples of the company's humanoid robots. Figure 1a The humanoid robot 1 shown in FIG. 1 includes a head 10 , a body 2 , two arms 3 , two hands 4 , two legs 5 and two feet 6 . Figure 1b The humanoid robot 1' shown in includes a head 10, a body 2, two arms 3, two hands 4 and a skirt 7. The present invention relates to hands with which these types of humanoid robots may be fitted.

[0027] The invention is hereinafter described in the specific case of the hand, which includes four fingers located in the palm. Three fingers made of three phalanxes like index finger, middle finger and ring finger. The fourth finger, made of two phalanges, resembles a thumb. Obviously the invention is not limited to this particular example, but more broadly covers a hand comprising a palm and a plurality of motor driven fingers enabling movement of the fingers relative to the palm in a human fashion. Furthermore, the invention is im...

Abstract

The invention relates to a hand to be provided on a humanoid robot. The hand includes a palm and a plurality of fingers (12, 13, 14). Each finger (12, 13, 14) is movable, relative to the palm, between a rest position, maintained by means of a spring effect, and a compressed position, obtained by driving a connecting part (22, 23, 24) using the palm countering the spring effect. Said hand is characterized in that it includes a motor-driven shaft (20), connected to the connecting part (22, 23, 24) of each finger (12, 13, 14), and configured such as to move at least one first finger (12) and at least one second finger (13), respectively, from the rest position to the compressed position, by rotating the motor-driven shaft (20), in a first rotational direction and in an opposite direction, respectively.

Description

technical field [0001] The invention relates to a hand intended for a humanoid robot. More particularly, it relates to a hand in which the fingers can be moved from a rest position to two different positions by a single actuator. Background technique [0002] The human hand is an extremely complex part of the human body. The human hand consists of a plurality of fingers connected around the palm joint of the hand. In addition, each finger has multiple phalanges that articulate with each other. Each joint is movable by means of muscles. Different articulations of the hand allow grasping of objects of different shapes. The relative position of the fingers and palm also enables the generation of signals or symbols that convey messages, such as index finger extended to point to an object or direction, thumb extended to express approval, etc. Therefore, controlling the movement of the fingers of the hand is particularly meaningful for enhancing the human-like attributes of r...
