机器人巡线是智能机器人中最为基本的任务之一,很多青少年机器人比赛都要求机器人有巡线的能力。机器人巡线时依靠的硬件是地面灰度传感器(红外传感器的一种),而巡线的方法从简单到复杂有很多种,巡线方法应用是否合理直接决定机器人完成任务的效能。一、巡线机器人看着走就像人在走路时需要看着道路,机器人在作出动作时也需要用“眼睛”来感应周围。这个“眼睛”就是传感器。智能巡线机器人所需的传感器并不太复杂,只需要一个红外传感器我们就能做出最简单的智能巡线机器人了。红外传感器(图1)由发光二极管和光敏晶体管组成。发光二极管发出的光经过反射被光
Robot patrol line is one of the most basic tasks in intelligent robots, many young robot competitions require the robot patrol line ability. Robot patrol the hardware relied on is the ground grayscale sensor (a kind of infrared sensor), and line patrolling method from simple to complex, there are many, patrol line method is reasonable and directly determine the performance of the robot to complete the task. First, the patrol line robot looked like walking when people need to look at the road, the robot in the action also need to use “eyes ” to sense around. This “eyes ” is the sensor. The sensors needed for smart patrol robots are not too complicated. With just one infrared sensor, we can make the easiest smart patrol robot. The infrared sensor (Figure 1) consists of a light-emitting diode and a phototransistor. Light emitted by the LED is reflected by the light
