Description
Technical field
The invention belongs to robot technical field, more particularly to a kind of fluid driving multidimensional adaptive robot arm device
Structure design.
Background technology
Robot is the important terminal that robot manipulation uses, and robot is using its paw crawl object or manipulates (such as
Mobile, rotation) object.The hand of robot can imitate the operating principle of human hand to manufacture, this robot for imitating human hand
Have been developed that typically there is multiple joints with multiple fingers, each finger, this hand is also referred to as humanoid robot hand
Or multifingered robot hands.
Multifingered robot hands are divided into Dextrous Hand and the major class of drive lacking hand two again, and two classes are not independent mutually, and the former refers to have
There are more than 3 fingers and the multifinger hand of more than 9 frees degree, the latter refers to that driver number on hand is less than joint freedom degrees number
Mesh.
Dextrous Hand is very advanced, and integrated level is very high, and sensing and control system are complicated, have the joint of more independent control
The free degree, it is capable of the multiple joints of control of dexterity, completes different gesture motions, object can be captured on one's own initiative.This respect portion
Typical Representative is divided to include:The Robonaut R2 hands of NASA's exploitation, the three of Tokyo Univ Japan's exploitation refers to fast machine people
Hand, the HIT-DLR-II hands of Chinese Harbin Institute of Technology and German Aerospace Center (DLR) joint research and development, Shadow companies of Britain
The Shadow hands ... of development.But Dextrous Hand also brings very cumbersome calculating, requirement of real-time control in crawl control
Height, manufacture and maintenance cost are expensive.
Drive lacking hand is a kind of intelligent machine, machinery is used in crawl between general industry clamper and Dextrous Hand
Mode reach less driver and drive more joint freedom degrees, and can adapt to capture different shape and size automatically
Object, sensing and control demand it is few, obtained more research in recent years.There are some drive lacking hands to be developed
Come, such as Laval University, Canada, Robotiq companies, Italian Prensilia companies, Dutch Delft universities, Harbin work
Sparetime university, BJ University of Aeronautics & Astronautics, Shanghai Communications University, the Central China University of Science and Technology and Hefei Institute Of Intelligent Machines Chinese Academy Of Sciences etc.
Mechanism has all researched and developed under-actuated robot hand.But drive lacking hand is still the contact point of multifinger hand, finger and object
Each segment surface is confined to, because fingers number is limited, the segment limited amount on each finger, therefore, it is impossible to accomplish more
Contact point, be unable to reach the adaptive of more direction, capture object adaptivity and crawl scope by larger limitation,
The stability of crawl need further to improve.
In terms of outward appearance does not imitate the particular kind of machine human hand of human hand, substantial amounts of commercial Application uses sucker, magnet or electrostatic
The modes such as absorption capture and operated object.Cornell Univ USA have developed a kind of universal gripper (U.S. patent Nos
US20130106127A1), passive adaptation object shape is gone using the interior grand deformable hymeniderm for measuring small sized particles material and gas
Shape, and be evacuated using the mode of negative pressure, a large amount of granular materials, which are detained, wherein produces obstruction hardening, reaches crawl different shape size
The purpose of object.The clamper is disadvantageous in that:1) external environment must be relied on to give the reaction force of object to reach
The deformation of hymeniderm, it is impossible to pick up the object (such as the apple played in the air) of no reaction surface, the clamper is difficult to grab
Take.2) employ substantial amounts of granular materials, granular materials number affect the effect of crawl, the abrasion of granular materials needs one
Changed after fixing time.
German FESTO companies have developed a kind of universal gripper, and the recessed cup of fluid and flexible strutting piece is filled using inside
Shape hymeniderm and the sucker of hymeniderm end reach the shape for removing passive adaptation object, and pull piston using negative pressure, by hymeniderm
Water is pumped into piston cylinder, so that hymeniderm active deformation reaches the purpose of crawl different shape object to hold object.Should
Clamper is disadvantageous in that:1) its end force of suction cup is limited, can not clamp heavier object.2) in the mistake of hymeniderm deformation
The sucker of its end is easily deformed in journey, and suction suction disappears, so as to cause crawl to fail.
Kyushu University have developed a kind of Unimate, be named as MR α hands, and magnetic rheological liquid is filled using inside
Hymeniderm goes the shape of passive adaptation object, after hymeniderm adapts to body form, the magnetic rheological liquid in hymeniderm is passed through into magnetic field, made
Magnetic rheological liquid solidifies so that hymeniderm is fixed, and reaches the purpose of crawl object.The clamper is disadvantageous in that:1) it is necessary
The reaction force of object is given to reach the deformation of hymeniderm by external environment, it is impossible to picks up the object (example of no reaction surface
Such as the apple played in the air), the clamper is difficult to capture.2) magnetorheological materials are expensive, and cost is high.3) clamper produces
Raw magnetic field can disturb the electronic component of robot controller, influence the stability of controller, and magnetic field can also interfere with it is attached
Near radio communication.4) hymeniderm passive adaptation body form, magnetic rheological liquid are in irregular container, the distribution of its internal magnetic field
Uneven, the intensity of variation of magnetic rheological liquid is uneven, influences grasp stability.
The content of the invention
The invention aims to overcome the weak point of prior art, with reference to sucker and the adaptive hand of ball-shaped fluidic
Advantage, a kind of porous twolayer fluid adaptive robot arm device is proposed, the device is used to capture object, can adapt to thing automatically
