循迹小车的追踪与避障

摘要

This paper introduces the design and realization of auto-tracking carts based on the use of gray level sensors. This cart tracks certain black lines on the white floor. When detecting objects at front, the cart starts to chase the object. By changing the pro- grams, the cart can avoid obstacles and turn itself automatically.%介绍了采用灰度传感器的自循迹小车的设计与实现，并加以追踪与避障的功能。采用与白色地面反差很大的黑色路线引导小车按既定路线前进，若接近开关检测到物体时，实现追踪功能。通过改编程序，同样利用这两个接近开关可实现避障功能，即遇到障碍物时，自动转弯。
