The present invention also provides a kind of pneumatic type lack of driven robot multi-joint finger apparatus that adopts said conformal self adaptation under-actuated robot finger device, it is characterized in that: comprise that n refers to section and the individual described joint of owing to drive of n-1, wherein n is the integer greater than 2.A kind of embodiment that adopts the pneumatic type lack of driven robot doublejointed finger apparatus of said conformal self adaptation under-actuated robot finger device like Figure 31 and shown in Figure 32, comprises that 3 refer to that section and 2 are described and owe to drive the joint.Figure 33 is the situation of this doublejointed finger grasping objects, and Figure 34 and Figure 35 are the situation of 3 doublejointed finger grasping objects.
The two ends of the spring spare among the present invention 8 connect first respectively and refer to that section 1 and second refers to section 2, and its function is: under the nature and when decontroling object, spring spare 8 makes pneumatic flexible piece 7 and air bag 4 resile, and has both kept pointing straight configuration; During grasping objects, spring spare 8 will be out of shape under the promotion of foreign object.Figure 10, embodiment illustrated in fig. 11 be exactly to have adopted extension spring, Figure 12, the torsion spring that just adopted embodiment illustrated in fig. 13.
Air bag 4 among the present invention adopts flexible material, and described flexible material can adopt plastics or soft rubber.
Introduce the operation principle of the embodiment of conformal self adaptation under-actuated robot finger device below in conjunction with accompanying drawing.
(i) if first of present embodiment is referred to that section 1 is fixed on the palm of anthropomorphic robot's hand, the operation principle of present embodiment, like Figure 23,24,25, shown in 26, narrate as follows:
When robot did not contact object, finger was in free state, and air bag 4 is not squeezed, and pneumatic flexible piece 7 is undeformed, and finger keeps straight configuration.
When the robot grasping objects, other fingers rotate back compressing object, object extruding gasbag 4; Pushing first refers to gas in section 1 through hole; Because the restriction of spring wire 732, pneumatic flexible piece 7 can radial deformations, only axial elongation and axial bending can take place; Spring wire is stretcher strain also; Strength will promote the second finger section 2 and make wide-angle rotational angle α around closing joint shaft 5 center lines, and till the second finger section 2 contacts objects, thereby this robot will have the automatic adaptability to object size, shape.This makes second to refer to that section has driver drives such as motor general seemingly when rotating, and can fasten object fast, has realized that finger self without driver, but can have the purpose of joint freedom degrees.
When robot is decontroled object; Other fingers leave object under motor rotates; Object is compression bladder 4 no longer just also; The back stretch of spring wire 732 will spur second and refer to that section is got back to around joint shaft 5 center lines and initially stretch the position that strength will push the interior gas of through hole this moment, make air bag 4 restPose and the position.Can also install a spring spare 8 in the present embodiment in addition additional and assist this process, can certainly not need this spring spare.
If (ii) first of present embodiment (embodiment illustrated in fig. 1) is referred to that section 1 root is fixed on the active joint shaft by driver drives, the operation principle of present embodiment, like Figure 27,28,29, shown in 30, narrate as follows:
When the robot grasping objects, rotate under driving moment m effect in the active joint that is with the first finger section 1, makes whole finger apparatus rotate around the center line of active joint shaft together with the active joint shaft of root; Up to air bag 4 contact objects; Because object can not leave under the effect of other fingers, so, when the active joint shaft is rotated further; Air bag 4 stops that object the foundation institute object appearance of grabbing is to internal strain under the extruding, and the process that grasps thereafter is with (a) similar.
Adopt the operating principle of the pneumatic type lack of driven robot multi-joint finger apparatus of said conformal self adaptation under-actuated robot finger device to be: when the robot grasping objects; Owe to drive for two and close the festival-gathering sequentially-operating, finally adapt to shape, the size of object automatically.This finger has the motor active drive general owing to drive joint seemingly.
Conformal self adaptation under-actuated robot finger device of the present invention adopts air bag as receiving gas in deformable member and the deformable confined space as transmission medium; But in conjunction with the pneumatic flexible piece of axial stretching and axial bending, any direction object extruding passive owes to drive bending effect when comprehensively having realized the finger grasping objects; The rotation that utilizes the very little conformal distortion of air bag can bring the second finger section wide-angle; This device does not limit the direction of object extruding gasbag, and extruding gasbag can cause the rotation of the second finger section arbitrarily; This conformal self adaptation under-actuated robot finger device is fit to be installed on the manipulator as a finger of anthropomorphic robot's hand or a part of pointing; Cooperate the finger of other active drive or other active drive joints on the finger to realize grasping objects, and have the adaptation function to the shape size of grabbing object, this apparatus structure is simple; Volume is little; Quality is little, and manufacturing and maintenance cost are low, and be similar with the finger of staff.This device can be together in series and constitute high form adaptive and the high multi-joint finger of owing to drive; Can also constitute anthropomorphic robot's hand that height is owed to drive with a plurality of such simple joints or multi-joint finger, in order to reach the high joint freedom degrees of anthropomorphic robot's hand, the adaptive effect of high extracting.
