摘要
为提高电脑鼠在迷宫中搜索并走出迷宫的速度,对MicroMouse 615电路和搜索算法进行改进,采用分组分时的方式驱动红外传感器,使信号采集更加迅速;采用定时器驱动步进电机匀加速的方法,使其运行更加平稳;采用新迷宫算法,使搜索算法更加简洁高效。采用基于RTOS的多进程架构实现各算法,用无线模块实现实时跟踪与可视化,使系统调试更加方便。
To improve the speed of maze searching and reduce the time spended on finding a shorter path to the destination, a improved circuit of MicroMouse615 and a new maze search algorithm are proposed. By grouping the infrared sensors and driving the infrared sensors in the time-sharing way, the signal can be acquired rapidly. Accelerating method is implemented by calculating the timer to drive the stepper motor, which runs more smoothly. A innovation of maze algorithm is offered, which makes it more easy to realize. RTOS-based frame for multi-process mechanism is used to achieve the above algorithm module. Real-time tracking and visualization of algorithm are achieved by wireless module which makes the system debugging more convenient.
