Embodiment Construction

[0026] Such as figure 1 Shown is a schematic diagram of the structure of the simulated hand of the present invention; the simulated hand of the present invention includes: five fingers 1, a palm 2, a wrist 3, and an arm 4. There are two driving sources for the simulated hand, which are a driving motor 6 and a straight line. The stepping motor 5 and the linear stepping motor 5 are used to drive the finger 1 to achieve a grasping action, and the drive motor 6 is used to drive the wrist 3 to rotate. Among them, the index finger 14, middle finger 15, ring finger 16 and little finger 17 of the five fingers 1 have the same structure, and the thumb 12 has an independent structure different from the above four fingers. The artificial hand of the present invention has a high degree of simulation that is consistent with a human hand, such as: the length ratio of each finger joint, the rotation angle, the distribution of each finger on the palm, etc., and the distribution of the fingers an...

Abstract

The invention relates to a simulated hand, which comprises fingers (1), a palm (2), a wrist (3) and an arm (4), wherein the fingers (1) are arranged on the palm (2) and comprise a thumb (12) and at least one other finger; the thumb (12) has two degrees of freedom; the other finger (1) has three degrees of freedom; the wrist (3) is connected to the palm (2) and the arm (4) and has a rotating degree of freedom; the simulated hand further comprises two driving sources, namely a driving motor (6) and a stepping motor (5); the stepping motor (5) is connected to the fingers (1) so as to drive the fingers (1) to realize the gripping action; and the driving motor (6) is connected to the wrist (3) so as to drive the wrist (3) to rotate. By using the simulated hand provided by the invention, the simulation for hand action can be realized by using few executing drivers, the structure of the simulated hand is simple and the simulated hand is reliable and durable.

Description

Technical field [0001] The present invention relates to the field of entertainment equipment and robots, and more specifically, to a simulated hand, which can imitate the posture of the open and close of a human hand and realize the grasping of objects, and can also be extended to other related movements of the simulated animal hand. Background technique [0002] Industrial manipulators are often specially designed to meet certain industrial needs. They do not have the emulation of human hands. The number of fingers also varies due to different needs, generally two or three so-called "fingers". At present, the general artificial hand, or dexterous hand, uses too many actuators, has a complicated structure, is expensive, and is difficult to maintain and repair, and is not suitable for general occasions such as entertainment. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an artificial hand in view of the above-mentioned s...
