Playing with your robot

After uploading the Arduino sketch, you are ready to play with the Zumo robot:

1. First, insert the batteries in the battery compartment of the Zumo robot.

2. Then, place the robot on the dark line of the race track and turn on the power button. The robot will start to follow the dark line (Figure 5.12). Line-following robots are very susceptible to light and ground texture changes and may show unexpected line-following behaviors. If so, adjust the contrast and lighting on the environment:
