Description

technical field [0001] The invention belongs to the technical field of micro-robots, and in particular relates to a diagonal sprint system based on a dual-core four-wheel high-speed microcomputer mouse. Background technique [0002] The microcomputer mouse is an intelligent walking robot composed of embedded microcontrollers, sensors and electromechanical moving parts. The microcomputer mouse can automatically memorize and select paths in different "mazes", and use corresponding algorithms to quickly reach the set goal land. The microcomputer mouse competition has a history of more than 30 years abroad, and now hundreds of similar microcomputer mouse competitions are held internationally every year. [0003] The microcomputer mouse competition uses three parameters: running time, maze time and touch, and is scored from three aspects: speed, efficiency of solving the maze, and reliability of the computer mouse. Different countries use different scoring standards. The most re...

Problems solved by technology

[0017] (1) As the eyes of the microcomputer mouse, ultrasonic or general infrared sensors are used, and the setting of the sensor is wrong, which makes the microcomputer mouse misjudgment the surrounding maze when it sprints quickly, so that the microcomputer sprints quickly. Sometimes it is easy to hit the front wall;

[0018] (2) The stepper motor is used as the actuator of the microcomputer mouse, which often encounters the problem of missing pulses, which leads to errors in the memory of the sprint position, and sometimes the end of the sprint cannot be found;

[0019] (3) Due to the use of stepping motors, the body heats up more seriously, which is not conducive to fast sprinting in large and complex mazes;

[0020] (4) Due to the use of a relatively low-level algorithm, there are certain problems in the calculation of the optimal maze and the calculation of the sprint path. The microcomputer mouse developed basically does not automatically accelerate the sprint for many times, and the sprint in the general maze generally requires It takes 15~30 seconds, which makes it impossible to win in the real international complex maze competition;

[0021] (5) Since the microcomputer mouse needs frequent braking and starting during the fast sprint process, which increases the workload of the single-chip microcomputer, the single-chip signal processor cannot meet the requirements of the fast sprint of the microcomputer mouse;

[0022] (6) Relatively, some relatively large plug-in components are used, which makes the microcomputer mouse relatively large in size and weight, and has a high center of gravity, which cannot meet the requirements of fast sprinting;

[0023] (7) Due to the interference of unstable factors in the surrounding environment, especially the interference of some surrounding light, the microcontroller controller often appears abnormal, causing the microcomputer mouse to lose control and have poor anti-interference ability;

[0024] (8) For the microcomputer mouse with differential speed control, it is generally required that the control signals of the two motors should be synchronized, but it is difficult for a single single-chip microcomputer, so that the microcomputer mouse will sway relatively slowly in the maze when sprinting at high speed. Large, often hit the wall, resulting in sprint failure;

[0025] (9) Due to the influence of the capacity and algorithm of the single-chip microcomputer, the microcomputer mouse does not store the information of the maze, and all the information will disappear when encountering a power failure, which makes the entire sprint process impossible to complete;

[0026] (10) Turning without the assistance of a
