Detailed description of the invention
Below in conjunction with Figure of description and specific embodiment, the utility model is described in detail:
Embodiment
Based on the induction machine mechanical arm of angular-rate sensor and acceleration transducer, angular-rate sensor 13 is placed in manipulator profile frame, manipulator profile frame is through in human arm, this angular-rate sensor 13 is in order to respond to control end, i.e. human arm, attitudes vibration, comprise angle and acceleration, then return apery mechanical arm to do equal work.
The joint of embodiment owing to being the medical-therapeutic treatment of human body mechanical arm overlapped in advance at human arm, put acceleration and angular-rate sensor 13 respectively, read the attitudes vibration of human body mechanical arm, realized the equal attitudes vibration of mechanical arm by two block controllers and wireless module, the attitude regulation precision overcoming existing body propagated sensation sensor is not high, cannot carry out micro-process, the problems such as production cost is higher, in scientific research, medical treatment, disaster relief field has a wide range of applications.
Manipulator external member comprises metacarpal bone part 4 and is movably connected in thumb part 5, forefinger part 6, middle finger 7, unknown finger 8, little finger 9 that metacarpal bone part 4 sets gradually, and metacarpal bone part 4 is formed with tiger's jaw, and thumb part 5 and forefinger part 6 points are located at the both sides of tiger's jaw; Each finger comprises the proximal phalanx part 10, middle phalanx part 11, the distal phalanx part 12 that are flexibly connected successively; Metacarpal bone part 4, proximal phalanx part 10, middle phalanx part 11, distal phalanx part 12 are respectively equipped with acceleration transducer 14, the active connection place of metacarpal bone part 4, proximal phalanx part 10, middle phalanx part 11, distal phalanx part 12 is provided with angular-rate sensor 13, as shown in Figure 1, Figure 2, Fig. 3, Fig. 4.
Mechanical arm external member comprises the humerus part 1, ulna part 2, the connectivity kit between carpal bone part 3 and joint that are flexibly connected successively; Acceleration transducer 14 is set at the humerus of mechanical arm external member, ulna, carpal bone place, at the shoulder joint of mechanical arm external member, elbow joint, articulatio radiocarpea, articulatio carpometacarpicus communis, articulations digitorum manus, angular-rate sensor 13 is set respectively, as Fig. 5.
First human arm need put on tool light weight and on-deformable aluminium alloy joint comprises humerus, ulna, carpal bone joint junction adopts has the mechanical arm external member that good plasticity and flexible stainless steel or bronze material makes, and staff also needs to bring tool plasticity and flexible manipulator external member.At human body mechanical arm stock, six axle sensors are installed at place, the value of acceleration is measured respectively by the sensor at humerus, ulna, carpal bone place, comprise direction and size, by measuring the value of angular speed at the sensor of shoulder joint, elbow joint, articulatio radiocarpea, articulatio carpometacarpicus communis, articulations digitorum manus, comprise direction and size, namely on human body machinery stock, acceleration and the angular speed that six axle sensors measure human arm 26 frees degree is installed.
Then, by attitude algorithm device, coordinate Kalman filtering can accurate output module is current under dynamic environment attitude, attitude measurement accuracy 0.01 degree, stability is high, above-mentioned data are sent to master control two ARM by master control one ARM by wireless device, and master control two completes synchronization action by controlling corresponding steering wheel.
It is 155*65mm that Apery manipulator makes size according to the proportional sizes of 1:1, the wrist joint of this manipulator is made up of four steering wheels, and each mechanical finger is by 2 frees degree, and the design's profile farthest can simulate staff, adopt aluminum alloy mass light, hardness is high.Specially with the addition of bearing in articulation part, moderate dimensions, smooth degree is reliable and stable.
The framework of mechanical arm external member copies human arm size, has 4 frees degree, puts the sensor of six axles as its transmission sources carrier at each steel joint.
By installing acceleration and the angular speed that six axle sensors measure human arm 26 frees degree on human body machinery stock.By attitude algorithm device, coordinate Kalman filtering can accurate output module is current under dynamic environment attitude, attitude measurement accuracy 0.01 degree, stability is high, the data gathered are sent to master control two by master control one by wireless device, master control two completes synchronization action, as Fig. 6 by controlling corresponding steering wheel.When MCU produces pwm signal, amplify through FET, series inductance before motor, interference to power supply when removing steering wheel motor starting and stop, during startup, electric current is larger, can in a flash supply voltage being dragged down of starting, because inductance can lead to low frequency resistance high frequency so the voltage change of power end when can reduce motor starting, thus its steady operation can be ensured.Play the effect of afterflow at motor two ends shunt capacitance, thus improve the average voltage of motor to a certain extent.
Below be schematically described the utility model and embodiment thereof, this description does not have restricted, and shown in accompanying drawing is also one of embodiment of the present utility model, and actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from this creation aim, designing the frame mode similar to this technical scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.
