(5), specific embodiments
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1, the force feedback data gloves driver rack that base plate 1, after-poppet 3, fore-stock 11 are formed partly passes through nylon silk ribbon band on forearm; The back of the hand connecting plate 10 is fixed on the back of the hand by the nylon silk ribbon; Joint base 19,20,21 is fixed on forefinger rear end, centre and the terminal joint by the nylon silk ribbon respectively.Because it is identical with the force feedback principle that each finger and finger are gone up the angular surveying in each joint, be that example describes with first joint (MP) of pointing near palm below.The braking air bag of being made up of air bag piston 4 and sebific duct 5 is connected with Pneumatic artificial muscle 9, and the artificial-muscle front end is connected with drag-line 12, and drag-line 12 is by flexible axle 13, and the axle 15 on the back base 14 is connected with the beam type force transducer 22 on the base 19.The slinky spring that resets is installed in the thin wall casing 6, and thin wall casing 6 is fixed together as an overall fixed on after-poppet 3 with sleeve pipe end cap 8. Connecting rod 16,18 is connected with back base 14, base 19.Simultaneously in conjunction with Fig. 2, non-contact angle sensor 17, be installed on the back link 16, front rod 18 is fixedlyed connected with turning cylinder 24, Magnet 23 is installed in turning cylinder 24 ends, the position of angular transducer is directly over turning cylinder, and when front rod 18 rotated with respect to back link 16 with turning cylinder 24 like this, Magnet rotated with respect to angular transducer.
Angular surveying principle of the present invention is: form a lanar four rod mechanism by back link 16, front rod 18, back base 14, base 19, first joint of forefinger.Based on plane four link motions really qualitative principles measure the angle of bend of finger-joint.When finger is crooked, angle between front rod 18 and the back link 16 relative motion that changes, Magnet in the rotating shaft 24 23 can rotate with respect to the angular transducer 17 that is installed on the back link 16 like this, the magnetic line of force direction of Magnet 23 can change with respect to angular transducer 17, angular transducer 17 is according to the angle between the direction change calculations connecting rod 16,18 of the magnetic line of force, according to the angle between the connecting rod 16,18, obtain the angle of bend of finger-joint by the geometric triangulation relation of four connecting rod inside, plane.Angular surveying is separate between each joint, is not subjected to the influence in other joints.
Force feedback principle of the present invention is: shrink the generation contractility by Pneumatic artificial muscle 9 inflations, finger-joint is produced force feedback.When the hands natural motion, the braking air bag is in the state of not inflating, and sebific duct 5 does not contact with thin wall casing 6, has only the bossing at air bag piston two ends to contact with thin wall casing 6, frictional force between the two is very little, and the power of finger impression is that the slinky spring 7 that resets is compressed the power of generation.The rigidity of slinky spring 7 is very little owing to reset, and the stroke that the braking air bag is produced is little, and is so the resistance that is produced by the slinky spring 7 that resets is very little, little for the power perception influence of finger.When the hands natural motion, when getting back to straight configuration by case of bending, the power of compressing slinky spring 7 generations that reset resets artificial-muscle 9 and braking air bag.When the virtual hand in the virtual environment touches dummy object, need produce force feedback to finger-joint, at this moment brake air bag by trachea 2 inflations, sebific duct 5 expands and contacts with thin wall casing 6, produces frictional force between the two and makes the stop motion of braking air bag.After the stop motion of braking air bag, inflation in Pneumatic artificial muscle 9, qigong artificial-muscle 9 produces the trend of shrinking and produces contractility, be delivered on the finger-joint through drag-line 12, in order to offset the contractility that Pneumatic artificial muscle 9 produces, finger-joint also produces the power of corresponding size by the muscle on the finger when grasping actual object, thereby produces force feedback, makes finger perceive the existence of power.Pneumatic artificial muscle 9 internal pressures can be mediated by the power size that is installed in the force sensor measuring on the base 19.When the virtual hand in the virtual environment was separated with dummy object, after Pneumatic artificial muscle 9 venting, the contractility of Pneumatic artificial muscle disappeared, the braking air bag deflation, and hands returns to the state of natural motion.
Fig. 3 has provided control survey systematic schematic diagram of the present invention.The present invention is controlled by industrial computer.Pressure in the Pneumatic artificial muscle 9 is by pressure proportioning valve 31 controls, and pressure proportioning valve provides control signal by the D/A integrated circuit board 33 in the industrial computer 32.The inflation of braking air bag 30 or venting are by electromagnetic switch valve 34 controls, and the DO integrated circuit board 35 control relay plates 36 in the industrial computer are controlled electromagnetic switch valves.The output signal of angular transducer 17 and force transducer 22 is through amplifying circuit 37, and behind the A/D integrated circuit board 38, by the industrial computer collection, the force signal that collects can be used for the feedback control of Pneumatic artificial muscle internal pressure.
