    Part 1  Objective

    After you upload the program, Land Raider goes straight forward. When the object to be followed is 40 cm or less ahead, Land Raider starts following it. When the object to be followed is over 40 cm or less than 8 cm, Land Raider stops moving.

    Part 4  Practice

    With the ultrasonic sensor and track, Land Raider can follow objects. Can you make Land Raider do something interesting with the ultrasonic sensor and other sensors?
