Obstacle Avoidance
=====================

This example project shows how you can make a robotic vehicle respond to its
environment using sensors. The robot drives at a given
speed until it detects an obstacle with the
:class:`UltrasonicSensor <pybricks.ev3devices.UltrasonicSensor>`. Then the
robot backs up, turns around, and continues driving until it detects a new
obstacle.
