受谷歌自动驾驶汽车的启发，自己开发了利用超声波探测技术，将采集的数据在matlab中绘图，其效果达到一个雷达搜索的雏形，即可扫描出前方障碍物。但由于传感器的距离限制，只能扫描5米的距离。-Inspired by the Google automatic driving a car that he developed the use of ultrasonic detection technology, data will be collected in matlab drawing, the effect reaches a prototype radar search, you can scan the front obstacle. However, the distance of the sensor limits the scanning distance of 5 meters only.
