[0002] In the field of education, artificial intelligence educational robots have gradually become an important auxiliary tool. Existing artificial intelligence educational robots usually include mobile components, display screens, cameras, and obstacle avoidance systems. These robots have some shortcomings in practical applications, which affect user experience and educational effects.

[0003] 1. The display screens in existing AI educational robots are usually exposed when not in use, which is prone to dust accumulation, affecting the display effect and service life. In addition, the angle of the display screen is fixed and cannot be adjusted according to user needs, resulting in a poor viewing experience.

[0004] 2. The obstacle avoidance system of existing AI educational robots is not perfect. When moving, they usually rely on pre-built maps and fixed obstacle information to avoid obstacles. However, in actual educational scenarios, especially when multiple robots are used at the same time, robots are prone to collisions, affecting normal operation.

[0005] Therefore, an artificial intelligence educational robot was proposed, which can protect the display screen, adjust the angle of the display screen, and convert the collision avoidance problem into a motion planning problem in velocity space based on the optimal interactive collision avoidance algorithm, thus safely and effectively solving the collision risk problem among multiple machines. Summary of the invention

[0006] The technical problem to be solved by the present invention is that the existing display screen is usually exposed when not in use, and dust is easily accumulated over a long period of time, making it difficult to clean. At the same time, the angle of the display screen cannot be adjusted, and when two robots are used at the same time, there is a risk of collision.

[0010] As a further solution of the present invention: the lifting assembly includes a motor fixedly arranged at the bottom of the storage groove, one end of the output shaft of the motor is fixedly connected to a screw, and one end of the screw is rotatably connected to the storage groove, a slider is sleeved on the screw, a connecting clamp 1 is fixedly arranged on the top of the slider, a connecting clamp 2 is fixedly arranged on the bottom of the receiving clamp, and a push rod is rotatably arranged between the connecting clamp 1 and the connecting clamp 2.

[0011] As a further solution of the present invention: the sliding block is slidably connected to the receiving groove.

[0012] As a further solution of the present invention: the collision avoidance system includes a speed set Set the collision time to t c ∈[0,θ], speed obstacle space In the velocity space, let the relative velocity V AB Deviate from area; at the same time, starting from the minimum principle, find the minimum offset Assume that A and B bear the same responsibility in collision avoidance, that is, η = 0.5; the ORCA area is perpendicular to μ and passes through point V A +0.5μ half-plane area; the ORCA area of ​​robot A relative to robot B is expressed as: Meanwhile, the ORCA area of ​​robot B relative to robot A is expressed as: Considering the speed limit, the set of allowed speeds of robot A is defined as the intersection of the ORCA space and the motion limit speed space: A new speed to solve collision situations A new collision avoidance speed is also calculated for robot B.

[0014] Beneficial effects of the present invention:

[0015] The present invention cooperates with the lifting component and the storage slot to store the display screen in the storage slot when the display screen is not in use, thereby preventing dust from adhering to the display screen when not in use, which would affect the display effect and life of the display screen for the next use.

[0024] The body 2 is provided with a collision avoidance system, and the collision avoidance system prevents the robot A and the robot B from colliding with each other.
