Description

Technical Field

[0001] The present invention relates to the field of robotics technology, and in particular to an AI intelligent educational robot. Background Art

[0002] Educational robots are finished robots, sets or parts specially developed by manufacturers to stimulate students' interest in learning and cultivate their comprehensive abilities.

[0003] After searching, Chinese invention patent CN117351816B discloses an educational robot, which belongs to the technical field of operating devices, and includes a base and a robot body above the base. A plurality of first support rods are elastically connected to the outer side of the base, and a sleeve is rotatably provided on the outer side of the first support rod, and a sliding rod is provided inside the sleeve below the first support rod, and a support wheel is installed at the bottom end of the sliding rod, and a connecting belt is provided at the base; the setting of the connecting belt is conducive to adjusting the position of the first support rod relative to the base on the one hand, thereby improving the stability of the movement of the base, and on the other hand, the use of the connecting belt can improve the ability of the entire device to avoid obstacles. In addition, when the support wheel is stuck in a pit, the connection belt can drive the sleeve to rotate, thereby driving the sliding rod to move upward so that the support wheel moves out of the pit, which is conducive to the normal driving of the entire device. In actual use, the connecting belt is made of plastic or fiber and other materials.

[0004] The above-mentioned device uses a connecting belt and a sliding rod to make the support wheel leave the pit, but this method is relatively simple and limited in adjusting the support area. When the support wheel is stuck in the pit, the sleeve is only driven by the connecting belt to rotate and the sliding rod is moved upward to move the support wheel out of the pit. This method may not be effective for larger or more complex pits, and has limited ability to cope with complex environments and tasks, and it is difficult to meet the needs of diverse educational application scenarios.

[0005] How to invent an AI intelligent educational robot to solve these problems has become an urgent problem to be solved by technicians in this field. Summary of the invention

[0006] In order to make up for the above shortcomings, the present invention provides an AI intelligent educational robot, aiming to solve the problems mentioned in the above background.

[0010] Preferably, the output end of the motor is connected to a chuck, and a mounting cavity matching the chuck is provided inside the chassis, and a connecting rope and a distance sensor are also connected to the end of the slider located inside the slide groove, and the connecting rope and the distance sensor are both located on the inner side of the fixed cylinder, and a passage matching the connecting rope is provided inside the chassis, and one end of the connecting rope extends into the mounting cavity after passing through the passage, and is clamped and installed on the chuck.

[0011] Preferably, two rotating wheels are rotatably clamped on the outer side of the fixed cylinder, and the two rotating wheels are respectively distributed on the upper and lower sides of the sliding block, and the rotating wheels on the same plane are connected through elastic bandage transmission.

[0012] Preferably, the plurality of slide grooves are equidistantly distributed in a circular shape around the central axis of the chassis, the end of the passage close to the mounting cavity is chamfered, the lower end of the fixed cylinder is flush with the bottom of the chassis, and the opposing surfaces of the electromagnet and the magnetic cylinder are magnetically set with different polarities when the electromagnet is energized, and the distance sensor, motor and electromagnet are electrically connected.

[0013] Preferably, the cross-sectional profile of the elastic bandage after installation is larger than the cross-sectional profile of the chassis.

[0015] The beneficial effects of the present invention are: With the cooperation of components such as motors, chucks, connecting ropes, sliders and springs, the robot can flexibly change the support area of ​​the chassis according to different terrains. On flat roads, reducing the support area makes the robot more flexible in narrow spaces and when turning; on uneven ground, increasing the support area can disperse the weight, improve stability, and prevent rollover and bumps; when encountering potholes, the mobile support assembly will first make adjustments, such as lifting the ball to avoid getting stuck, and reducing the support area to reduce the risk of collision.

[0016] The rolling ball at the lower end of the magnetic cylinder plays an auxiliary supporting role during the movement of the robot, especially when turning or passing through uneven ground. It can reduce the pressure on the electric wheels and enhance the stability of the robot.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1, refer to Figure 1-Figure 6 , an AI intelligent educational robot, comprising a robot body 1 and a chassis 2 arranged at the bottom of the robot body 1, an electric wheel 92 is arranged at the bottom of the chassis 2, a turntable 91 is connected above the base of the electric wheel 92, the electric wheel 92 at the bottom of the chassis 2 is combined with the turntable 91 above, so that the robot has flexible movement ability, a display screen 11 is arranged on the front side of the robot body 1 for displaying teaching content and other information, and also includes: Mobile support assembly: The mobile support assembly is arranged on the chassis 2; Induction lifting component: The induction lifting component is arranged in the robot body 1 and the chassis 2.

[0022] Furthermore, support rods 43 are symmetrically installed on the edge of the chassis 2, and the support rods 43 are used to support and fix the chassis 2 to enhance the overall stability of the robot.

[0023] The mobile support assembly includes an elastic bandage 3, a slider 4, a rotating wheel 5 and a motor 8. One end of the slider 4 is connected to a fixed cylinder 41, and the motor 8 is installed at the bottom of the robot body 1. A plurality of slide grooves 22 matching the slider 4 are arranged inside the chassis 2. The end of the slider 4 located inside the slide groove 22 is elastically connected to the slide groove 22 through a spring 1 42, which can achieve a certain degree of buffering and resetting. A sliding cavity 411 is arranged inside the fixed cylinder 41, and an electromagnet 413 and a spring 2 412 are installed on the top of the sliding cavity 411. The lower end of the spring 2 412 is connected to a magnetic cylinder 414, which is slidably connected to the sliding cavity 411. A rolling ball 415 is rotatably clamped at the lower end of the magnetic cylinder 414. Through the setting of the spring 2 412, when the robot moves, the rolling ball 415 can contact the ground to achieve auxiliary support for the robot.

[0024] Furthermore, the output end of the motor 8 is connected to a chuck 81, and the interior of the chassis 2 is provided with an installation cavity 21 matching the chuck 81. The end of the slider 4 located inside the slide groove 22 is also connected to a connecting rope 6 and a distance sensor 7. The connecting rope 6 and the distance sensor 7 are both located on the inner side of the fixed cylinder 41. The interior of the chassis 2 is provided with a passage matching the connecting rope 6. One end of the connecting rope 6 extends into the installation cavity 21 after passing through the passage, and is clamped and installed on the chuck 81. When the motor 8 rotates, the connecting rope 6 is retracted and released by the chuck 81, thereby pulling the slider 4 to slide in the slide groove 22; two rotating wheels 5 are rotatably clamped on the outer side of the fixed cylinder 41, and the two rotating wheels 5 are respectively distributed on the upper and lower sides of the slider 4. The rotating wheels 5 on the same plane are connected through an elastic bandage 3 for transmission. The elastic bandage 3 can provide protection for the bottom of the robot to prevent foreign objects from directly contacting the robot body 1, thereby playing a role of buffering and adaptive adjustment.

[0025] A plurality of slide grooves 22 are equidistantly distributed in a circular shape around the central axis of the chassis 2, ensuring that the elastic bandage 3 can maintain a relatively stable state. The end of the passage close to the mounting cavity 21 is chamfered to facilitate the retraction of the connecting rope 6. The lower end of the fixed cylinder 41 is flush with the bottom of the chassis 2 to ensure that the normal movement of the chassis 2 is not affected. When the electromagnet 413 is energized, the opposing surfaces of the electromagnet 413 and the magnetic cylinder 414 are magnetically set with different polarities. The distance sensor 7 and the motor 8 are electrically connected to the electromagnet 413. The distance sensor 7 is used to detect the position information of the slider 4 and transmit the signal to the electromagnet 413 and the motor 8 to control their operating status.

[0026] It should be noted that the cross-sectional profile of the installed elastic bandage 3 is larger than the cross-sectional profile of the chassis 2 , ensuring that the chassis 2 can be effectively protected.

[0027] In this embodiment, when the support area of ​​the chassis 2 needs to be changed, the motor 8 starts to work, and the rotation of the motor 8 drives the chuck 81 connected to its output end to rotate. The rotation of the chuck 81 will retract and release the connecting rope 6. When the chuck 81 retracts and releases the connecting rope 6, it will pull the slider 4 to slide in the slide groove 22. When the slider 4 is pulled by the connecting rope 6 to slide toward the installation cavity 21, the spring 1 42 is compressed to store elastic potential energy; when the motor 8 is reversed and the chuck 81 releases the connecting rope 6, the elastic potential energy of the spring 1 42 is released, pushing the slider 4 to reset. The change in the position of the slider 4 directly causes the position of the fixed cylinder 41 to change. 1, and finally realizes the adjustment of the support area of ​​the chassis 2. For example, when multiple sliders 4 slide toward the installation cavity 21 at the same time, the fixing cylinder 41 gathers inward, and the effective support area of ​​the chassis 2 is reduced; on the contrary, the slider 4 slides outward, the fixing cylinder 41 extends outward, and the support area of ​​the chassis 2 is increased. In actual educational application scenarios, the robot may need to move in a variety of environments, such as the flat ground of the classroom, the uneven floor tiles of the corridor, or the grass outdoors. By flexibly adjusting the support area, the robot can better adapt to these different environments, ensure the smooth progress of teaching tasks, and provide users with more reliable services.

[0028] Specifically, on a flat road, the stability of the robot is relatively easy to maintain, and a smaller support area is sufficient to meet the demand. At this time, the control chuck 81 pulls the connecting rope 6 inward to reduce the support area. The smaller support area allows the robot to complete actions more easily in narrow spaces or scenarios that require flexible turning, thereby improving the robot's operational convenience. When the robot passes over uneven ground, the larger support area helps to disperse the robot's weight, improve stability, and prevent the robot from tipping over or excessively bumping due to uneven local force. The control chuck 81 releases the connecting rope 6, allowing the slider 4 to slide outward, increasing the support area of ​​the chassis 2, and allowing the fixing cylinder 41 and related components such as the elastic bandage 3 and the rolling ball 415 to better adapt to complex terrain. The rolling ball 415 can roll on the ground at different heights to provide additional support points, thereby jointly ensuring that the robot can travel smoothly on uneven ground.

[0029] The lower end of the magnetic cylinder 414 is rotatably clamped with a ball 415. When the magnetic cylinder 414 slides upward, the ball 415 rises; when the magnetic cylinder 414 slides downward, the ball 415 drops and contacts the ground. During the movement of the robot, the ball 415 can play an auxiliary support role, reducing the pressure on the electric wheel 92, especially when turning or passing through uneven ground, which can enhance the stability of the robot.

[0030] When encountering a pit, the pit will block the rotating wheel 5 and the fixed cylinder 41, forcing them to move inward. At this time, the distance sensor 7 connected to the end of the slider 4 will detect the position information of the slider 4 in real time. When the slider 4 slides to a specific position, the distance sensor 7 transmits a signal to the electromagnet 413 and the motor 8 to control them to be energized. After the electromagnet 413 is energized, since the opposite surface of the electromagnet 413 and the magnetic cylinder 414 has different magnetic polarities, an attraction will be generated, attracting the magnetic cylinder 414 to overcome the elastic force of the spring 2 412, slide upward in the sliding cavity 411, lift the magnetic cylinder 414 upward, and make the ball 415 higher than the bottom of the chassis 2. The purpose of this is to prevent the ball 415 from being stuck when crossing the pit, thereby eliminating potential obstacles for the robot to smoothly cross the pit.

[0031] If the robot still cannot escape from the pit, the motor 8 will start accordingly, and it will pull the slider 4 inward through the chuck 81 to reduce the support area. The smaller support area makes the robot more flexible when crossing the pit, reduces the risk of contact and collision with the edge of the pit, and reduces the possibility of falling into the pit. When the robot successfully crosses the pit, the distance sensor 7 detects that the slider 4 returns to its normal position and sends a signal to cut off the power to the electromagnet 413. At this time, the elastic force of the spring 2 412 recovers and pushes the magnetic cylinder 414 to slide downward and reset, and the ball 415 also returns to its initial position, providing auxiliary support function for the robot again.

[0032] The elastic bandage 3 connects several wheels 5 to form a structural system surrounding the outside of the robot. This connection method makes the elastic bandage 3 have a certain degree of integrity and stability, and can maintain a relatively fixed position and shape during the movement of the robot, laying a structural foundation for the realization of the protection function, and being ready to deal with possible collisions at any time. The cross-sectional profile of the elastic bandage 3 after installation is larger than the cross-sectional profile of the chassis 2. The larger profile enables the elastic bandage 3 to form a buffer area between the robot and foreign objects. No matter from which direction the foreign objects approach the robot, the elastic bandage 3 can be the first to contact, ensuring that the robot body 1 will not directly collide with foreign objects in most cases, greatly reducing the damage to the robot. The risk of collision is reduced by the early contact mechanism, which can firstly apply the impact force of the collision to the elastic bandage 3, and use its elastic characteristics to preliminarily buffer the impact force. Compared with the direct collision of the robot body 1, the elastic bandage 3 can absorb part of the energy, reduce the transmission of the impact force to the precision parts inside the robot, and protect the core structure and electronic components of the robot. In addition, the elastic bandage 3 is elastic and can adaptively deform according to the angle and strength of the collision when it contacts with foreign objects. It can wrap the foreign objects to a certain extent, prevent them from getting closer to the robot body 1, prevent sharp objects from scratching or hitting the robot shell, and also prevent smaller foreign objects from entering the robot and affecting its normal operation.

[0033] Example 2, refer to Figure 2-Figure 8 The inductive lifting assembly includes several hydraulic cylinders 9 installed in the robot body 1. The number of hydraulic cylinders 9 is equal to the number of electric wheels 92. The output end of the hydraulic cylinder 9 passes through the top wall of the chassis 2 and is fixedly connected to the top of the turntable 91. The hydraulic cylinder 9 is electrically connected to the distance sensor 7.

[0034] In this embodiment, the inductive lifting assembly is an important structure for the AI ​​intelligent educational robot to cope with complex terrain. When the robot encounters a large pit and the adjustment of the mobile support assembly in Example 1 cannot get it out of trouble, the inductive lifting assembly comes into play. It uses the distance sensor 7 to monitor the condition of the pit and drives the turntable 91 and the electric wheel 92 to move through the hydraulic cylinder 9, thereby changing the height of the chassis 2 and enhancing the robot's ability to cross the pit.

[0035] The distance sensor 7 continuously monitors the position information of the slider 4. When the robot falls into a larger pit, the position of the slider 4 in Example 1 is continuously in an abnormal state due to the obstruction of the pit. The distance sensor 7 will detect a continuous abnormal distance signal, which reflects that the obstacle currently encountered by the robot exceeds the adjustable range of the mobile support component. The distance sensor 7 will accurately send the detected continuous abnormal distance signal to the hydraulic cylinder 9. When the hydraulic cylinder 9 receives the signal from the distance sensor 7, it starts to work. The output end of the hydraulic cylinder 9 extends outward, pushing the turntable 91 and the electric wheel 92 connected thereto to move downward. Since the turntable 91 and the electric wheel 92 are connected to the chassis 2, their downward movement directly increases the height of the chassis 2 relative to the ground.

[0036] The increase in the height of the chassis 2 increases the space between the bottom of the robot and the bottom of the pit, which provides more sufficient space for the robot to cross the pit and reduces the possibility of collision between the bottom of the robot and the edge or bottom of the pit. After raising the chassis 2, the electric wheel 92 can better adjust its position and posture when crossing the pit and more effectively utilize its own driving force. At the same time, the increased height causes a certain change in the center of gravity position of the robot, which is beneficial to improve the force distribution of the robot in the process of crossing the pit, and improve the stability and success rate of crossing.

[0037] The inductive lifting assembly cooperates with the mobile support assembly in Example 1 to form a multi-level terrain adaptation mechanism. When the mobile support assembly cannot solve the problem, the inductive lifting assembly can further play a role, greatly enhancing the robot's adaptability to complex terrain and broadening the robot's usage scenarios. The distance sensor 7 automatically detects and transmits signals to control the action of the hydraulic cylinder 9, thereby realizing the robot's intelligent judgment and automatic adjustment of pit conditions. This intelligent design reduces human intervention and improves the robot's autonomous operation capability and work efficiency.

[0038] It should be noted that the specific models and specifications of the motor 8, hydraulic cylinder 9, distance sensor 7, etc. need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
