SONAR obstacle-avoidance robot
An Arduino robot that ranges with SONAR and steers around whatever is in front of it.
LABRobots
A small Arduino rover with an HC-SR04 sonar head on a servo rolls toward a wall while the sonar pings; as the echoes shorten it stops, the head looks left and right, and the rover backs away.
Arduino, real-time ranging
SONAR for object detection, Arduino for the loop. The robot adjusts heading in real time and stays out of walls. A small machine for a large lesson: sensors first, path second.
