Double-core intermediate speed four-wheel mini mouse spurting controller

Abstract

The invention discloses a Double-core intermediate speed four-wheel mini mouse spurting controller, comprising a main board, and a battery, a first sensor S1, a second sensor S2, a third sensor S5, a fourth sensor S6, a first motor X, a second motor Y, a third motor R, a fourth motor Z, a fifth motor M, a three-axis gyroscope G1, a three-axis accelerometer A1, and a vacuum device, which are arranged on the main board. Through above arrangement, the double-core high-speed four-wheel mini mouse controller can perform monitoring and operation on the mini mouse operation state all the time, and utilizes four sensors to detect, which reduces the interference and accurately monitors the surrounding environment. Besides, the invention corrects the moving posture according to the moving state, anew distributes torque and distributes more torques to the driving wheel which is not in stall, enables the system to quickly get out of the unstable state and automatically regulates the absorption of the vacuum device to the ground and completely eliminates the slipping of the mini mouse exploring in the complicated maze.

Description

technical field [0001] The invention relates to an automatic control system of a PICOMOUSE, which belongs to the field of miniature labyrinth robots. Background technique [0002] The microcomputer mouse is an intelligent walking robot composed of embedded microcontrollers, sensors and electromechanical moving parts. It has been competing abroad for nearly 30 years. It often adopts a two-wheel structure. The two-dimensional structure of the two-wheel microcomputer mouse is as follows: figure 1 shown. The microcomputer mouse can automatically memorize and select paths in different "mazes", and use corresponding algorithms to quickly reach the set destination. figure 2 It is one of the mazes solved by the microcomputer mouse. [0003] With the continuous advancement of microelectronics technology and computer control technology, foreign experts have proposed a more challenging maze robot --- Weimouse, based on the technology of microcomputer mice to solve mazes. In order to...

AI Technical Summary

Problems solved by technology

[0006] 1. Due to the large increase in the number of mazes to be solved, the original microcomputer mouse maze-solving technology cannot be used to solve the existing complex mazes of Picomouse, and cannot provide an optimal sprint path for high-speed sprinting

[0007] 2. Since the size of the pico mouse is greatly reduced compared with that of the micro computer mouse, if the pico mouse uses figure 1 The six sets of sensors of Zhongwei computer mouse make the sensors interfere with each other when the pico mouse updates the complex maze for the second time, which leads to the failure of pico mouse to read and update the maze information when sprinting at high speed

[0008] 3. The wheel-based picomouse can only passively adapt to the slippery degree of the maze floor. With the increase of the sprint speed of the picomouse, its slipping probability also increases greatly, resulting in failure to solve the maze

[0009] 4. Because the microcomputer mouse servo system uses relatively low-level algorithms, if these algorithms are directly applied to the Weimouse, it will generally take a long time for the Weimouse to sprint in the maze, which makes it difficult to compete in real competitions. can't win in

[0010] 5. Due to the reduction in the size of the maze wall, the single-cell running distance of the Pico Mouse is reduced compared with that of the Micro Computer Mouse. The frequent braking and starting of the Pico Mouse during high-speed sprinting increases the workload of the single-chip microcomputer. A single single-chip computer cannot meet the needs of the Pico Mouse. Rat quick sprint start and stop requirements

[0011] 6. Due to the influence of the capacity of the single-chip microcomputer, the existing microcomputer mice basically only have two power driving wheels, and use the two-wheel differential mode to drive, which makes the system have higher requirements for the two-axis servo, especially when the linear acceleration sprint navigation, It is required that the speed and acceleration should be strictly consistent, otherwise the straight-line navigation will fail, and using the existing microcomputer mouse directly for the PicoMouse will easily cause the PicoMouse to hit the wall
