Chapter 10. Autonomous Movement
This chapter describes how to use a distance sensor to enable the robot to see and avoid
obstacles as it moves around. The first sketch, named myRobotWander, drives
the robot forward, and if it detects an obstacle, it stops and rotates the robot to try and
find a clear path to move forward. Another sketch, named myRobotScan, adds
a servo that can rotate the sensor so the robot can look left and right without having to
twist itself around.
