摘要
超声波传感器被广泛应用于机器人避障系统中。基于超声波的测距原理,设计了一种并行测距系统。介绍了系统的硬件组成和软件实现方法。针对多路传感器并行测距容易产生干扰的现象,分析了干扰产生的原因,提出一种有效的解决办法。将系统用于移动机器人避障实验,给出了系统测量范围的实验标定结果。
Ultrasonic sensors are widely used in mobile robotics. A parallel distance measurement system based on ultrasonic range-finder is designed. The hardware and software design of the system is presented. After analyzing the disturbance reasons,a method is published to avoid the disturbance of sensors. The system is applied in the avoiding obstacle experoments of mobile robotics. The calibration results of the system＇ s measurement range are obtained.
