The grasping means of electromagnetism joint Manipulator of the present invention, comprises the steps:
A, the record bending amplitude in each joint of human hands, dynamics and crawl attitude.
B, composition that multiple electromagnetic flexible joints are together in series emulation joint, the upper plate in electromagnetic flexible joint, downside and upside electromagnetism The lower plate of flexible joint is fixing to be connected, and the amplitude in joint at reference man's palmistry co-located, adjusts the number in electromagnetic flexible joint.
C, by machinery palm, mechanical finger, mechanical arm with emulation joint connect.
Electromagnetism joint Manipulator difference from prior art of the present invention is that electromagnetism joint Manipulator of the present invention is closed by electromagnetic flexible Joint replaces the mechanical joint of gear-rack drive capture object (such as dixie cup) or epidemic victim is carried out feeding, it is possible to Play electromagnetic flexible joint and to adjustability during tiny error.When mechanical hand captures dixie cup, electromagnetic flexible closes festival-gathering and imitates people Fat on hand thus share equally dixie cup outside extend out power, successfully capture dixie cup and do not destroy dixie cup.Pass at mechanical hand feeding Catch an illness people time, decrease the probability that medical personnel are infected, and patient contain spoon shut up down swallow when, electricity Action of bowing when magnetic flexible joint also can be swallowed for patient moves downward with patient, greatly reduces the probability accidentally injuring patient. Three telescopic masts in electromagnetic flexible joint according to 0 ° of lower plate circumference, 120 °, 240 ° of circumferences be uniformly distributed, then can be flexible When post stretches, change the angle of upper plate and lower plate, so that the arbitrarily angled bending in electromagnetic flexible joint.Wherein telescopic mast utilizes electricity Magnet and permanent magnet control flexible, then may utilize Magnet and drive push rod to move up and down at the repulsive force of homopolarity, it is achieved stretching of expansion link Contracting.And the flexible sleeve of round table-like inner chamber can limit its maximum displacement when permanent magnet rises as guide rail.
If push rod is rigid posts in electromagnetism joint Manipulator of the present invention, may utilize spring and eliminate the bending between push rod top and upper plate Power.
In electromagnetism joint Manipulator of the present invention, flexible push rod then can eliminate the bending force between push rod top and upper plate voluntarily.But it is soft Property bar easily mutually friction in flexible sleeve, or produce skew, then arranging spacing ring carries out spacing to permanent magnet, in passing to soft Property push rod play the guiding role.
In electromagnetism joint Manipulator of the present invention, if desired expansion link has enough extending forces, then the magnetic of the powerful electromagents to be added that are bound to. But three expansion link hypotelorisms after all, interfere and easily cause driving confusion, then coaxial spaced on the barrel of flexible sleeve Embed ring shielding magnetism and can reduce interfering of three expansion links, and only 0.0508 milli that Mumetal material can make The magnetic shield thin slice ring that rice is thick, then its frivolous performance does not affect the degree of crook of expansion link, and is electromagnetic flexible joint loss of weight. Interval between ring shielding magnetism is more than ring shielding magnetism height 1/5, then do not reach good Magnetic Shielding Effectiveness.During use, first stores Battery, the second accumulator one of them because of the magnetic induction line wire cutting coil not shielded between ring shielding magnetism, thus to it Power supply, another electric magnet electric discharge to telescopic mast, interleaved power, electric discharge can work and charge, and protects accumulator Life-span.
It is a point and the contacting of face that electromagnetism joint Manipulator midpoint of the present invention limit set contacts with each other, and its advantage is flexible for turning to.
In electromagnetism joint Manipulator of the present invention, face limit set contacts with each other is an elongated cambered surface.Its advantage is for keeping attitude the most steady Fixed.
In the grasping means of electromagnetism joint Manipulator of the present invention, the electromagnetic flexible of the different number of degree of crook regulation of simulating human hands closes Joint series winding, can copy staff to manufacture mechanical hand so that it is purposes is the most extensive to greatest extent.
Below in conjunction with the accompanying drawings the electromagnetism joint Manipulator of the present invention and feeding thereof and control method are described further.
