How to Build an Object Following Robot?

Overview
In the previous project, we have built an ultrasonic following robot combined with ultrasonic module and robot
bottom shield. But the robot can't turn around, only follow in a straight line.
We're now ready to give the Micro:bit robot another upgraded capability - Object Following!
Combine ultrasonic module, infrared detector sensor and robot shield to build an obstacle following robot that
can turn around.
How does it work?
The principle is very simple. We will use an ultrasonic module to measure the distance between the micro:bit
robot and an obstacle ahead. Then detect the left and right side obstacles using infrared obstacle sensors;
control the running state of micro:bit robot according to the measured result.
