-4-DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
The present invention overcomes the disadvantages of the prior art by providing an interactive robotic toy which can cling to a finger of a person. The robotic toy exhibits a plurality of physical animations in response to user actions. Such actions may include kissing, cradling, hanging upside down, petting and the like. The physical animation is a combination of sound and motion and may include head motion, eyes blinking or sound animations (e.g., sound of laughing, sound of sneezing, sound of a kiss and the like).
Reference is now made to Figures 1A-1G, which is a schematic illustration of to an interactive robotic toy, generally referenced 100, constructed and operative in accordance with an embodiment of the disclosed technique. Figure 1A is an isometric front view of Interactive robotic toy 100. Figure 1B is an isometric front back of Interactive robotic toy 100. Figure 1C is a front view of Interactive robotic toy 100.
Figure 1D is a side view of Interactive robotic toy 100 and Figure 1E is a back view of Interactive robotic toy 100. Interactive robotic toy 100 includes a body section 102 and a head section 104 rotatably coupled with body section 102. Interactive robotic toy 100 further includes flexible left and right arms 106L and 106R
respectively, flexible left and right legs 108L and 108R respectively and a flexible tail 110.
Flexible left and right arms 106L and 106R, flexible left and right legs 108L
and 108R and flexible tail 110 are all coupled with body section 102. Body section further includes a batteries cavity in which batteries are located, covered by battery cover 120. Head section 104 includes left and right eyes 112L and 112R, a mouth opening 114, an on-off switch 116 and loudspeaker holes such as hole 118. Left and right eyes 112L and 112R may be embodied as spheres rotating about an axis perpendicular to axis 115. Half of the spheres are of a color similar to the body color

-5-of interactive robotic toy 100 (i.e., emulating eye lids). This half is referred to herein as the "lids side". The other half of the sphere are of a dark color (e.g., black) thus emulating the eyes, referred to as the "eyes side". When Left and right eyes 112L and 112R are rotated such that the eyes side thereof are facing the user, Left and right eyes 112L and 112R appear to be open. When Left and right eyes 112L and 112R are rotated such that the lids side thereof are facing the user, left and right eyes 112L and 112R appear to be closed. Alternatively, left and right eyes 112L and 112R
include respective left and right eye lids 113L and 113R operable to cover or uncover the respective left and right eyes 112L and 112R (i.e., close or open left and right eyes to 112L and 112R). Interactive robotic toy 100 may cling to a finger of a user via the flexible limbs thereof (i.e., left and right arms 106L and 106 R, left and right legs 108L and 106 R or tail 110). A cross sectional view of interactive robotic toy 100 is depicted in Figure 1E.
As mentioned above, interactive robotic toy 100 includes a plurality of physical animations in response to various actions by the user. For example, when interactive toy 100 is turned on, interactive robotic toy 100 may sound a laugh, and blink. When hanged upside down via tail, interactive robotic toy 100 may produce sounds associated with excitement. When cradled, interactive robotic toy 100 may produce sounds associated with content and close eyes 112L and 112R.
With reference to Figures 1F and 1G, a system 125 operating interactive robot toy 100 is located within head section 104. The power supply (e.g., batteries) operating the system are located within body section 102. The system operating interactive robotic toy 100 includes an eyes blink actuator 124, at least one touch sensor 126, a motor and gears 130, a speaker 132 attached to a PCB 142 and at least one sound sensor 134 (e.g., microphone) and at least one orientation sensor 140 (e.g.,

-6-ball switch, gyroscope, Accelerometer). Eyes blink actuator 124 includes a solenoid 136 and a magnet 138. The operation of the system operating an interactive robotic toy such as interactive robotic toy 100 is further explained in conjunction with Figure 2.
Reference is now made to Figure 2, which is a schematic illustration of a system, generally referenced 200, for operation an interactive robotic toy, in accordance with another embodiment of the disclosed technique. System 200 includes a processor 202. System 200 further includes at least one touch sensor 204, at least one sound sensor 206, an orientation sensor 208, an eyes blink actuator 210, a to motor 212, a speaker 214 and a memory 216 all coupled with processor 202. Eyes blink actuator 210 may be embodied as a solenoid and a magnet or as a motor and gears. Touch sensor 204 is, for example, a capacitive touch sensor. Sound sensor 206 may be embodied as a microphone. Orientation sensor 208 is, for example, at least one ball switch, a gyroscope or an accelerometer, detecting information relating to the orientation of interactive robotic toy 200 about selected axes. Memory 216 stores a plurality of physical animations for interactive robotic toy. A physical animation is defined as a combination of sound animation and motion animation. A motion animation is, for example, the motion of the head and the blinking of the eyes of the interactive robotic toy.
Touch sensor 204 detects touch, for example, on the head section of the interactive robotic toy, produces a signal indicative that the head section was touched and provides that signal to processor 202. Orientation sensor 208 detects information relating to the orientation of interactive robotic toy 200, produces a signal or signals respective of this information. Sound sensor 208 detects sound in the vicinity of the interactive toy, produces a signal indicative to that sound and provides this signal to

-7-processor 202. As mentioned above, interactive robotic toy may include two or more sound sensors, which define an array of microphones.
Processor 202 receives the signals produced by touch sensor 204, sound sensor 206 and orientation sensor 208. Processor 202 determines when interactive robotic toy 200 was touched according to the signal received from touch sensor 204.
Processor 202 determines when a sound was made in the vicinity of interactive robotic toy 200 and the nature of this sound (e.g., the detected sound is a sound of a kiss). For example, processor 202 compares the time signature or the frequency signature (e.g., a Fourier Transform of the time signal) or both to stored signatures.
to When an array of microphones is employed processor 202 may further determine the direction from which the sound arrived at interactive robotic toy 200, for example, by employing interferometry techniques or correlation based techniques (e.g., Multiple Signal Classification ¨ MUSIC).
Processor 202 selects a physical animation or animations associated with the received signals and the information (e.g., nature of the received sound received, direction or arrival of the received sound or the orientation of interactive robotic toy 200) derived therefrom. Once processor 202 selects the physical animation or animations, processor 202 produces corresponding signal to eyes blink actuator 210, motor 212 and speaker 214 to produce the selected animation.
For example, when the interactive robotic toy is held upright and touched on the head, motor 212 moves the head from side to side and speaker 214 produces a laughing sound. As a further example, when the interactive robotic toy is held horizontally (e.g., cradled) eyes blink actuator 210 rotates the eyes or the eye lids such that the eyes of the interactive robotic toy appear closed and speaker 214 produces a snoring sound.

-8-As another example, when the interactive toy is held upside down, orientation sensor 208 detects the orientation of interactive toy 200 and provides processor 202 with information relating thereto. Consequently processor 202 instructs eyes blink actuator 210 to rotate the eyes or the eye lids such that the eyes of the interactive robotic toy appear, and speaker 214 produce a sound associated with excitement (e.g., a "Yehh" cry).
As yet another example, when a user kisses the interactive robotic toy (i.e., sound sensor 206 detects the sound of a kiss), the speaker 214 produces the sound of a kiss. Furthermore, when an array of microphones is employed and the direction of to arrival of the sound is determined, motor 212 rotates the head of the interactive robotic toy to turn toward the direction from which the sound arrived.
The interactive toy according to the disclosed technique may be in the form of different animals and creatures. For example, interactive toy 100 (Figures 1A-1G) exhibits the form of a monkey. However, the interactive toy according to the disclosed technique may exhibits forms of other animals and creatures. The physical animation or animations which the interactive toy produces correspond to the animal or creature. For example, a monkey shall produce sound corresponding to a monkey.
A dinosaur or a lion shall produce corresponding roars animating anger, or purrs animating pleasure or content (e.g. when the head of the interactive toy is stroked).
With reference to Figures 1G and 2, the interactive toy system (e.g., interactive toy system 125 ¨ Figure 1G or interactive toy system 200 ¨ Figure 2) may include at least two touch sensors located on the head. When a user strokes the head of the interactive toy, touching the two touch sensors in sequence (e.g., petting the interactive toy), these touch sensors shall produce a signal in sequence. The processor (e.g., processor 202) detects this sequential touching of the two touch sensors and

-9-interprets this as action of stroking. Thereafter, processor 202 may select a pacified or content animation. For example, the user may stroke the dinosaur and the processor shall select a purr sound. According to another example, when the user shakes the dinosaur, the dinosaur roars. Shaking is detected, for example, according to the derivative of the orientation of interactive toy 200.
The interactive toy according to the present invention may further interact with the user by opening and closing the mouth thereof. Reference is now made to Figures 3A-3F which are schematic illustrations of an interactive toy, generally referenced 300, constructed and operative in accordance with a further embodiment of the to disclosed technique. Interactive toy 300 is similar to interactive toy 100. However, interactive toy 300 exhibits the form of a dinosaur. Interactive toy 300 interacts with the user as described above in conjunction with Figures 1A-1G and 2 and further interacts with the user by opening and closing the mouth thereof. For example, as the head of interactive toy 300 rotates, the mouth of interactive toy 300 opens as further explained herein below.
With reference to Figure 3A, head 302 of interactive toy 300 is in a forward position relative to body 304. With reference to Figure 3B, head 302 is rotated to the left from the forward position thereof. As head 302 rotated from its forward position, jaw 306 of the mouth of interactive toy 300 opens. Jaw 306 is coupled with head 302 via hinges such that jaw 306 can open and close.
With reference to Figure 3C, a cam 308 is rigidly coupled with body 304 (i.e., cam 308 and body 304 do not move one with respect to the other). Cam 308 includes two protrusions, a first protrusion 310 and second protrusion 312. With reference to Figure 3D, jaw 306 exhibits a general shape of the letter 'LP. A lever 314 is coupled with jaw 306 such that when lever 314 rises, jaw 306 also rises. Lever 314 also

-10-exhibits the general shape of the letter `U'. Each end of lever 314 is coupled with a respective end of jaw 306.
With reference to Figure 3D, interactive toy 300 is depicted with head 302 in the forward position. In this position, protrusion 310 pushes on lever 314 upward and lever 314 closes jaw 306. With reference to Figure 3F, the body of a motor 316 coupled with head 302 at the inner side thereof. The rotating shaft of motor 316 is coupled with cam 308. As the rotating shaft of motor 316 rotates, head 302 also rotates relative body 304 and protrusion 310 moves relative to U shaped lever toward of the ends of U shaped lever 314. Consequently jaw 306 is lowered by the to force of gravity and the mouth of interactive toy 300 opens.
According to another embodiment of the present invention, jaw 306 may be coupled directly or via lever 314 to a solenoid or a motor which actively lowers and raises jaw 306.
While only a single preferred embodiment of the present invention has been disclosed for purposes of illustration, it is obvious that many modifications and variations could be made thereto. It is intended to cover all of those modifications and variations which fall within the scope of the present invention, as defined by the following claims:
