Embodiment
Bottom combines accompanying drawing and specific embodiment that the present invention is elaborated, and specifically provides the method that the control of robot emotion realizes under a kind of situation, but the scope that does not limit the present invention in any way.
For human; No matter be perception or rational judgement; On its external expression-form the same (for example the someone is smiled and perhaps glare at); So the present invention's behavior that robot is all is defined as rational behavior, just before output, weighted calculation is carried out in perception judgement and rational judgment, finally obtain the output voltage of emotion simulation.The emotion simulation of robot of the present invention is as prerequisite.
The discovery of memristor is basic for the device that physics realization is provided of robot learning to a great extent; With weighted calculation being carried out in the perception judgement and the rational judgment of robot through the improved adder circuit of memristor; Finally can obtain the output of emotion simulation, the present invention is an output voltage values.As shown in Figure 1, the circuit that is used for robot emotion simulation comprises: microprocessor 1 is used to handle the information of carrying out the emotion simulation; Storer 2, in order to the experience understanding of storage for things, as the experience storehouse, it comprises perceptual memory block and rational memory block, stores the perceptual experience value of representing perceptual knowledge and the rational empirical value of representing rational knowledge with the mode of numerical value respectively; Through the improved adder circuit of memristor; Because memristor can alive outside control change its resistance value down; Expression formula Vo=Vin1Rf/M1+Vin2Rf/M2 according to output voltage V o can know; Substitute without the resistance in the improved totalizer with memristor; Can make that the weight Rf/M2 of weight Rf/M1 and rational input voltage vin 2 of perceptual input voltage vin 1 is able to programme, will pass through the improved adder circuit of memristor and be used for the perception of robot is judged and weighted calculation is carried out in rational judgment, obtain output voltage; Represent the different reaction of robot with different output voltage, thereby realize the emotion simulation of robot with the form of output voltage to things.
With such a case is the concrete approach that example is explained above-mentioned emotion mimic channel: the emotion of robot of the present invention is divided into two kinds of attitudes: like and dislike; Difference according to the degree of attitude is divided into four kinds of reactions: the smile of attitude and embracing of doubling are liked in expression, expression dislike attitude ignore and double glare at.Robot runs into a people; This people is a toad of robot from perceptual aspect; Be one from rational aspect and respected and cup of tea by the people, but robot dislikes this people's attitude generally, the value representation control robot of output voltage is to this people's attitude; Embodiments of the invention are just listed out four kinds of different reactions for the sake of simplicity, can be divided into more kinds of different reactions according to people's actual conditions.
At first the resistance of each resistance in the circuit shown in Figure 1 is once set: Rf=10k Ω, the Standard resistance range of memristor are 1k Ω~100k Ω.The control of input voltage vin 1 and Vin2 and output voltage V o can have two kinds of different selections.First kind, with input voltage and output voltage on the occasion of representing respectively that with negative value the attitude liking, dislike, the height of the absolute value of voltage of output voltage values represent the degree height of corresponding attitude, the absolute value that can get input voltage is 0.2V.The reaction of the interval pairing robot of the scope of output voltage is: embrace---Vo>2V, smile---and 0V<Vo≤2V, ignore----2V<Vo≤0V, glare at---Vo≤-2V.Second kind, input Vin1, Vin2 all adopt 0.2V voltage, and the reaction of the pairing robot of scope of output voltage is: embrace---and Vo>3V, smile---2V<Vo≤3V, ignore---1V<Vo≤3V, glare at---Vo≤1V.Be divided into perceptual memory block and rational memory block in the storer, be respectively applied for the stored in form of numerical value attitude and degree thereof for the perceptual knowledge and the rational knowledge of specific matters.Corresponding to the method that above-mentioned two kinds of voltages are set, storing value can have two kinds of methods to the setting of the resistance of memristor.Corresponding to first kind of voltage setting method; The positive and negative expression respectively of storage availability value is liked and is disliked; And set the positive and negative of Vin1, Vin2 with this, set the resistance of corresponding memristor with the size of storing value, such as reading a numerical value in the perceptual memory block--5; The perceptual input voltage vin 1 that the expression perception is set in expression is-0.2V that the M1 resistance is set at 1k Ω.Corresponding to second kind of voltage setting method; Because input voltage is positive voltage; Therefore the positive negative reaction of storing value is that the corresponding memristor resistance that needs to set its resistance intermediate value (being 10k Ω in this example) of comparing is big (storing value for just) still little (storing value is to bear); The size of absolute value is represented the amount that departs from, and such as reading a numerical value-1 in the rational memory block, the resistance that the rational memristor M2 that represent rational faculty is set in expression is set at 10-1=9k Ω.Certainly only be to provide corresponding storing value method for expressing here to above-mentioned two kinds of voltage setting methods; Storing value is not limited in above-mentioned two kinds of methods to the establishing method of the resistance of memristor and the value of pairing memristor resistance, and any coding method without prejudice to this circuit operation thought all is feasible.
Above-mentioned setting is for the ease of the selected particular value of the explanation of the embodiment of the invention; Do not represent all situations of circuit of the present invention; Can set the resistance size of the memristor of resistance, voltage setting way and interval division, the method for expressing of setting storing value and correspondence during practical operation according to specific requirement flexibly, all various situation all belong to this patent protection domain.
Choose aforementioned first kind of voltage setting method and storing value below and represent way, utilize the emotion mimic channel to carry out the described example of preamble.When that man-hour described in the preamble example is run into by robot; Perceptron receives this people's information; And this information is delivered to hub processor carry out pre-service; Extract the information that to carry out the emotion simulation, then this is inputed to the microprocessor that carries out the emotion simulation through the information that pretreated needs carry out the emotion simulation.The information that microprocessor carries out emotion simulation is as required sought corresponding or similar experience and (can be divided by memory address from storer; Also can divide according to other modes), read corresponding perceptual storing value and rational storing value respectively in the perceptual memory block and the rational memory block of storer.Since robot run into to be one be a toad of robot from perceptual knowledge, is one from rational knowledge and receives very much the people to respect the people with cup of tea, but robot dislikes this people's attitude generally; Therefore should to satisfy perceptual storing value be negative value to storing value, rational storing value be on the occasion of, the absolute value of the two is that perceptual storing value is greater than rational storing value; Therefore can suppose that the perceptual storing value that reads is-5, rational storing value is 1, the meaning of representing according to aforementioned storing value; Microprocessor is set at 1k Ω with phase M1; M2 is set at 5k Ω, sets input voltage vin 1=-0.2V, Vin2=0.2V at input end; Output voltage V o=Vin1Rf/M1+Vin2Rf/M2=-1.6V then; Drop on-2V<Vo≤0V is interval, and according to aforementioned definitions, the reaction that this output voltage can control robot be taked this people to ignore under the effect of back-end circuit is to respond.
What should explain at last is: above embodiment is only in order to technical scheme of the present invention to be described but not limit it; Although the present invention has been carried out detailed explanation with reference to preferred embodiment; Those of ordinary skill in the art is to be understood that: it still can make amendment or be equal to replacement technical scheme of the present invention, also can not make amended technical scheme break away from the spirit and the scope of technical scheme of the present invention and these are revised or be equal to replacement.
