Description

RELATED APPLICATIONS

This application claims priority to U.S. Provisional Patent Application No. 61/907,635 filed Nov. 22, 2013, which is hereby incorporated by reference in its entirety.

FIELD

The present invention relates to toy entertainment devices, and more particularly to motorized, movable toys.

BACKGROUND

Motorized toy vehicles are popular among children because they allow the children to imitate a real life action, such as driving a car or the movement of a pet. Normally, these toys are controlled remotely through a hand held control and the child inputs physical commands directing the toy to move a specific direction by pressing a button or using a joystick. Children enjoy controlling remote cars, and enjoy playing with toys that operate autonomously. Children also enjoy autonomous vehicles that mimic real-life play of animals or real-life driving actions of vehicles. However, there is a need for a toy that can interact with its environment and perform an action in response to stimuli while being able to track an object in a playful manner, similar to a real pet or a real vehicle interacting with an object.

SUMMARY

The present disclosure is directed to an autonomous toy that is capable of exploring its environment. In an exemplary embodiment, an interactive toy and a wireless signal source are provided. The interactive toy is capable of moving autonomously in its environment through movements controlled by control circuitry of the toy. The exemplary embodiment further includes a source of a wireless signal which is physically separate from the toy. The interactive toy includes two or more sensors capable of detecting the at least one wireless signal, and control circuitry that is capable of analyzing the wireless signal detected by the sensors and directing the toy towards a source of the wireless signal. The toy performs a trick once the toy is within a predetermined distance of the source of the wireless signal, wherein the toy is capable of performing more than one trick when within the predetermined distance of the source, and the trick performed is determined by the wireless signal emitted by the source of the wireless signal.

DETAILED DESCRIPTION

The present disclosure describes various embodiments in detail herein below with reference to the embodiments. It should be understood that the invention is not limited to the specific configurations shown and described in these embodiments, rather, one of skill in the art will appreciate that a variety of configurations may be implemented in accordance with the present invention.
In an exemplary embodiment, an interactive toy and a wireless signal source are provided, where the interactive toy includes a cover. The cover of the toy is in the shape of a dog or kitten; however, the shape may be in any form such as a car, robot, or spaceship. Construction of the toy may be from a wide variety of materials such as, but not limited to, plastic or plush fabric. The toy contains at least one motor capable of turning wheels forward and backward. The toy's exploratory movements are based on a predetermined path providing sounds and movements in timed sequences. Additionally, the toy is capable of receiving a wireless signal or signals from a source and interrupting its predetermined path by performing new actions, such as moving towards the source of the signals. Further, when the wireless signal or signals reach a certain strength or density, or the toy moves within an area to receive a second signal or signals, a new reaction or behavior is performed such as a dog performing a trick. The wireless signal may be a light source, such as infrared light. The receivers may be arranged to detect a signal from different sides of the toy, such as being arranged on the front, back, or sides of the toy.
As the toy is in active use, the toy explores its environment, moving in straight or curved lines in multiple directions, while performing actions and sounds in predetermined time intervals and in response to stimuli or obstacles in the environment. Once the toy detects a wireless signal, the toy reacts by moving towards the wireless signal. Then, once it reaches a predetermined distance from the source of the wireless signal, the toy performs a new action, such as a trick. The toy may interact directly with the source in a new way extending the play such as a dog chasing a ball, finding the ball, rising up on its rear wheels and engaging the ball by pushing it away, then chasing the ball again to repeat the play. All without user input. This creates the impression that the toy, such as a dog or car, is self-aware and acting like a real life item, such as a pet or car with a driver. The wireless signals may be detected by a receiver on one side of the pet, causing the pet to turn towards the signal, and then turn again if the signal is detected on another side of the pet, this turning and movement will continue until either the signal strength of the wireless signal reaches a certain strength denoting a distance from the source; or the toy moves within an area where a second signal is received by the toy. The action upon reaching a specific distance from the source may include a trick, such as spinning, rising up on its rear wheels (popping a wheelie), or another action. Additionally, a sound may be made at this predetermined distance. However, a trick involves something more than simply a sound. The source of the wireless signal may be a handheld device, a stationary device, a device with the ability to move (such as a ball), or another vehicle, such as another pet.
The toy comprises: (1) a motive component having a drive mechanism, receivers, and circuitry, with the circuitry configured to control the drive mechanism, respond to user inputs, perform tricks or generate predetermined sounds at specific times, and respond to detected wireless signals directing the drive mechanism to move the toy towards the source of the wireless signals; (2) a source of wireless signals having the ability to output a first wireless signal that can be detected by the toy causing it to move toward the source of the wireless signal, as well as the ability to provide a second signal to cause a reaction by the toy 100 at a certain distance from the source.
1. Cover
The cover 101, shown in FIG. 1, is configured to resemble a puppy dog or kitten with fur, eyes, ears, nose, whiskers, and tail. It should be noted that this cover could depict any object, such as any other animal, an alien, a ground transportation vehicle or a flying vehicle. The cover may be made of any material, including plush fabric, plastic, any polymer, any textile material, or metal. At least one switch 102 is positioned on the cover 101 such that the switch may be activated through pressure applied to the corresponding area of the cover. The switch may be embedded in the cover or raised above the cover. Operation of the control switch provides a signal to the control circuitry of the toy to perform a specific action.
At least one switch 102, located on the top or back 103 of the toy 100, is able to take the toy 100 from “sleep mode” to “explore mode”, wherein the toy 100 begins to move about and make noises. There may also be other switches embedded or raised above the cover, on the front 104, head 105, or rear 106 of the toy 100. These additional switches might be capable of causing the toy to activate, create noises, or otherwise perform an action.
The cover 101 has at least one receiver 107 embedded in the front 104 therein to receive wireless signals. The front 104 of the toy cover could consist of two receivers 107 in the shape of eyes capable of receiving wireless signals. These receivers would preferably be able to detect light signals and particularly, infrared signals. Additionally, the cover 101 may have two areas in the rear 106 of the toy capable of permitting a wireless signal, such as infrared light, to pass through the cover to a receiver, such as an infrared receiver.
2. Chassis
As shown in FIG. 2, the chassis 108 is generally made of a plastic, though it may be made of metal or another material. Two wheels 109 sit in the back of the chassis. The front of the chassis 108 may consist of one wheel 110, a third wheel, with the ability to articulate around a pin. It should be understood that there may be more or less than three wheels. For example, this same invention may be used with an 18 wheel truck, or a bicycle, as well as a four wheel vehicle.
The rear wheels 109 may be larger than the front wheel 110 or other wheels on the chassis 108. Further, the center of gravity of the toy may be placed over the back wheels 109, or near the back wheels, to assist in causing the toy to ride only on the back wheels in certain instances. It should be understood that the center of gravity may be placed in several areas of the vehicle to provide the ability to lift the vehicle onto two wheels at a given instance. For example, the center of gravity could be placed on one side of the vehicle to allow the vehicle to ride on its side.
3. Drive Mechanism
The drive mechanism 111, as shown in FIG. 3, is located in the rear of the chassis 108, though it could be located at any part of the toy 100. It includes at least one motor in mechanical communication with the rear wheels 109 capable of turning the wheels forwards or backwards. There may also be two motors 112 each capable of turning one wheel forwards or backwards. The motor is controlled by the control circuitry of the toy which provides power to the motor. This control circuitry is able to change the command signal thereby driving the motor in a forwards or backwards direction.
The drive mechanism may include the motors 112 and the motor controllers 112A. The motor controllers 112A communicate with the integrated circuit 113 of the toy and control the motor 112 in its movements. It should be noted that a motor controller is not necessary for the invention and such movements may be controlled by an integrated circuit alone. An example of a motor controller is the AMMD2A by Alpha Microelectronics Corp.
The drive mechanism 111 of the toy with two motors 112 is capable of spinning the motors at different rates and in different directions to allow the toy to turn or spin. The drive mechanism is capable of turning both wheels at a fast pace or a slow pace. Further, the wheels may be turned such to cause the toy to ride only on two rear wheels (pop a wheelie) or perform other tricks as shown below.
4. Control Circuitry of the Toy
The control circuitry of the toy includes an integrated circuit 113 on which may sit a microcontroller. The integrated circuit 113 of the toy has input connections to at least one receiver 114 and at least one switch 115 (shown in FIG. 1 as 102). The integrated circuit 113 of the toy 100 has output connections to a speaker 116 and at least one motor 112.
The integrated circuit 113 of the toy 100 has programming written thereon which allows the toy to move about and explore its environment. This programming is located on the memory of the integrated circuit 113 of the toy 100 and sets forth a specific set of instructions the toy follows when in “explore mode.” This may include a list of movements driving the motors 112 forward and backward at different rates causing the toy to move in straight and curved lines around an area. This may also include a list of sounds to be output from the speakers 116, in conjunction with the movements or separate from the movements.
The integrated circuit 113 of the toy 100 has inputs from receivers 114 (shown in FIG. 1 as 107 and 107.1) and at least one switch 115. In a preferred embodiment, there would be at least four receivers 114. The receivers 114 are capable of providing input to the integrated circuit 113 of the toy 100 such that each receiver 114 is read separately by the integrated circuit of the toy. The switch can place the toy in “explore mode” or “sleep mode”. When in “explore mode” the toy moves under a predetermined set of commands which are directed by the integrated circuit. When the receivers 114 detect a signal, they send inputs to the integrated circuit 113 of the toy 100. The integrated circuit 113 of the toy 100 reads the inputs and then directs the motors 112 to move the toy 100 towards the source 117 of the wireless signals. When the toy 100 is within a predetermined distance 133 from the source 117, the receivers 114 are able to receive a second wireless signal, which the receivers 114 input to the integrated circuit 113 of the toy 100 and direct the motors 112 to perform a trick 134. The software of the integrated circuit 113 of the toy 100 is able to provide the specific actions the toy 100 will perform.
The integrated circuit 113 of the toy 100 controls motor or motors 112 and controls the voltage and current output to the motor. The integrated circuit 113 of the toy 100 is able to switch signals provided to drive the motors 112 in either the forward or reverse directions to control the movement of the motive component.
A switch 115 or switches act as inputs to the control circuit of the toy providing input by the user. If additional switches are used, these switches may also act as inputs from obstacles or other components depending on their placement. For example, where another switch is on the front of the toy it may be depressed when hitting an obstacle at the front of the toy. Pressing the switch 115 on the back 103 of the toy inputs to the integrated circuit 113 of the toy that the toy 100 is either in “sleep mode” or “explore mode”. Pressing the switch and placing the toy in “explore mode” causes the toy 100 to enact a script of movements and noises which mimic the actions of a toy exploring its surroundings.
5. Receivers
The receivers 114 are capable of receiving wirelessly emitted signals and transmitting those signals as inputs to the control circuitry of the toy 100. The receivers 114 may be capable of receiving multiple different signals including, but not limited to, electromagnetic radiation signals (radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays) or audio signals. These receivers 114 may be sensors capable of detecting analog or digital signals. Preferably, the receivers 114 are capable of detecting infrared signals. These sensors may detect infrared signals through a band-pass filter, such that they are able to detect infrared light from a particular frequency range.
The invention is not limited in the number of receivers that could be placed on the toy 100 or the location of receivers 114 that may be placed on the toy 100. Preferably, at least two receivers 107 will be placed on the front 104 of the toy 100. These receivers may be in the form or appearance of eyes at the front of a vehicle. Further, preferably, at least two receivers 107.1 may sit at the rear 106 of the toy. The rear receivers may sit under the cover, with the infrared signal capable of reaching the receivers through the cover. An additional receiver or receivers may be placed on the top or back of the toy to note wireless signals directed to the top of the toy.
The receivers 114 would be understood by the control circuit of the toy and would provide an input to the integrated circuit 113 of the toy 100 such that the motors 112 would be driven to drive the toy in different directions. Preferably, the receiver (one of those at 114) detecting a wireless signal, such as an infrared signal, would then provide information to the control circuitry of the toy to drive one of the motors 112 slightly more than the other to turn the toy in the direction of the wirelessly emitted signal.
Preferably, the receivers 114 are capable of receiving modulated wireless signals with different instructions encoded therein, or capable of reading wireless signals at different frequencies. In a preferred embodiment, the receivers are capable of receiving multiple frequencies or modulations of infrared signals and able to transmit those signals to the control circuitry of the toy 100. The control circuitry of the toy 100 is then capable of distinguishing between the different modulated infrared signals and can control the motors 112 of the toy to perform actions, such as moving towards the source 117 or performing tricks 134.
6. Source
The source 117 of the wirelessly emitted signal, as shown in FIGS. 4, 5, and 6, may be of any shape or any size. Preferably, it would be in the form of a hand held source 118, a stationary source 119, or a moveable source 120, such as a ball. The source would have at least one emitter 121 that emits the wireless signal, but may have many emitters 121 therein. Preferably, the source would have a switch or button 122 that would allow the source 117 to be turned on or off. Further, this source 117 could have an indicator light 123 to indicate that it is on and sending out a wireless signal.
Preferably, the handheld source 118 of FIG. 4, could be in the form of something the toy would be attracted to, such as, but not limited to, a treat. The handheld source 118 could have any number of emitters 121. Preferably, the handheld source 118 would have a single emitter 121 placed at the front of the device. This would permit the signal, such as an infrared signal, to exit the source in a single direction so one could lead the toy 100 in a direction without the toy 100 being drawn in another direction.
The stationary source 119 of FIG. 5, could be in the form of, but not limited to, a stand with a sign or flag. The stationary source 119 could have any number of emitters 121. The stationary source 119 preferably has four emitters 121, one facing out in each direction for the middle height of the stationary source. Further, the stationary source 119 is capable of changing the signal it is sending to the toy through a switch or button 124. This change would cause the toy 100 to perform a different trick 134 when the toy 100 comes within a predetermined distance 133 of the source 117. The stationary source switch 122 is not explicitly shown, but could be on the underside of the stationary source.
The movable source 120 of FIG. 6, could be in the form of something the toy would normally play with, such as, but not limited to, a ball or a roll of yarn. The movable source 120 preferably has emitters 121 arranged around the ball at different locations such that the wireless signal, such as an infrared signal, is capable of being transmitted in different directions regardless of the position of the ball. In one embodiment, there could be four emitters 121 placed on each outward side of the ball in a single plane from its stationary position. Additionally, the ball could have five emitters with four emitters along a plane and an emitter on top of the ball. Further, the ball could have six or more emitters spread around the ball.
7. Control Circuitry of the Source
The source 117 of the wireless signal may contain a wireless signal emitter 121 and an integrated circuit 125 connected to a power source 126. The integrated circuit 125 of the source 117 may provide the programming necessary to control the emitter 121.
In a preferred embodiment, the control circuitry of the handheld source 118, as shown in FIGS. 7 and 8, the stationary source 119, as shown in FIG. 10, and the movable source 120, as shown in FIG. 9, may include an infrared LED emitter 121 connected to an integrated circuit 125. The infrared LED emitter 121 may be connected with two different resistors 127 so that the infrared LED 121 is capable of emitting at two different strengths, allowing a signal to reach a farther distance, such as the radius 132 where the toy detects the emitter to track to the source 117, preferably at six feet, while another signal is only capable of reaching a predetermined distance 133 of preferably one and a half feet. The shorter distance would be one where, once the toy 100 reaches this distance, the toy performs a trick 134. These examples should not be considered limiting, this emitter may be capable of emitting to any distance, such as 20, 15, 10, or less feet. Examples of the different resistance that can provide different distances include lower resistances of 200 Ohms or 390 Ohms as compared to higher resistances of 2,000 Ohms, 3,000 Ohms, or 3,900 Ohms. Further, by connecting different components, listed as different options 128, the source 117 is capable of having the toy 100 perform different tricks 134.
The trick 134 may be caused by an emitted signal operating simultaneously with the original signal, such as through a separate emitter, or in sequence with the original signal from a single emitter. These different signals which cause the toy 100 to move towards the source or cause the toy to perform a trick 134 may be created by the software of the emitter allowing a different wireless signal to be sent at a different frequency or modulation. Further, the different distances reached by the emitted signal may be caused by hardware, such as resistors shown above, or also by a separate emitter with a different emitting distance. Similarly, the different frequency or modulated signal may be caused by a separate emitter emitting a separate frequency or modulated signal which is read at a different distance from the source than the primary frequency or modulated signal.
In a preferred embodiment, the source may have software capable of driving an infrared LED 121 at two particular frequencies. When the frequency to cause the toy 100 to track to the source 117 is used, the integrated circuit 125 of the source inputs to a different location or can direct a switch 129 to cause the infrared LED 121 to emit at a longer distance through a resistor 127. When the frequency to cause the toy to perform a trick is used, the integrated circuit 125 of the source inputs to a different location or can direct another switch 129 to cause the infrared LED 121 to emit at a shorter distance through a different resistor 127 (see two resistors at 127, wherein the higher resistance should relate to a shorter distance, such as the predetermined distance).
8. Operation of the Toy
The toy is a capable of interacting with its environment once the switch is set in “explore mode” 130, as shown in FIG. 11. This causes the toy 100 to move forward and backward while turning to move about an area. These movements are predetermined and may be arranged in a variety of ways. These movements should not to be limited to one specific form or description.
The interaction with the environment could include a preprogrammed chain of events. The length and amount of the preprogrammed steps is not limited to a certain amount or time frame.
An example of a preferred embodiment could start with the toy being placed in “explore mode”, then the toy makes a noise, then moves forward in a straight line and then moves forward while curving to one direction, then moves forward while curving in another direction, and then begins to spin. After spinning, the toy could proceed in a large curve. The toy then could reverse while turning in a direction. All of this may occur while the toy makes periodic noises. This sort of programming could be repeated, or continue with many different preprogrammed steps.
Further, the toy may have a list of the types of movements it can make, and the ability to randomly choose which movement the toy will make. This may also involve the ability to randomly make noises and sounds.
Once the toy enters the radius 132 to detect a wireless signal, the toy reacts by moving towards 131 the wireless signal and once it reaches a predetermined distance from the source 117 of the wireless signal, the toy performs a trick 134. This reaction is caused by the receivers 114 on the toy 100 receiving the wireless signal, transmitting this signal to the control circuitry of the toy, which then transmits a signal to the motors 112 to drive the toy in the direction of the signal. Signals received from the left front receiver 114 would cause the toy 100 to drive the motors 112 towards the left front and the toy would then continuously process and move towards these signals until the toy 100 is a predetermined distance 133 from the source. At this distance, the toy 100 would perform a trick 134.
The tricks 134 a toy 100 may perform, as shown in FIGS. 12-15, include moving from one side to another while sitting on its rear wheels (resembling a dog begging for a treat) 135, spinning around in a circle (resembling a dog chasing its tail) 136, charging at the source (such as a dog pouncing on an object) 137, or moving from side to side (resembling a dog wiggling with excitement) 138. Particularly, where a toy 100 is made to charge forward or beg, the motor 112 drives the toy 100 in reverse and then drives the motor 100 forward allowing the front of the toy to rise up due to the location of the center of gravity of the toy being on the rear wheels. Further, the toy 100 may make noises throughout its movements or tricks. These tricks should not be considered limiting as the toy could be of any shape or character.
The distance from the source may be determined by the strength of the wireless signal or from a specific code in the signal that is read at a specific distance from the source. With regard to the strength of the signal, the toy may be able to process an analog signal and measure the increase in strength due to the analog signal increase. Also, the source may be capable of sending a second signal that is capable of being detected at a range that is closer to the source than the first wireless signal. These examples, of finding the distance between the toy and the source, should not be considered limiting.
Multiple toys may be used with the same source and the toys will both move towards the wireless signal. Further, the toy may interact with a moveable source, such as a ball, and engage the ball causing it to move, and then continue to push the ball. The toy is also capable of interacting with another device placed around the source, such as wobbly toys 139.
