Prepare a black track (the width of the black track must be between 20mm and 30mm) in
white ground. Please be noted that the bend angle of track can’t be too sharp otherwise
the car will move out of the track.
Turn on the car and put the middle of tracking sensor module facing over black track, and
then the car will move along the black track automatically.

Motor Speed Tuning for better tracking performance
To get better tracking performance result, motor power(speed) value should be adjusted
properly as per battery level. If motor power(speed) value is too high, your car might
run too fast and easy to get out of track. If motor power(speed) is too low, the car
might not even move.
To adjust the motor power value, you need change the 3 constants : MID_SPEED,
HIGH_SPEED,LOW_SPEED in line 13,14,15 in mecanum-2560-lesson3.ino sketch file. Their
default values are 70,80,60 which are good when batteries are fully charged.
After batteries are running low, you might need to increase the value of these 3
constants. You can gradually add or reduce 10 each time on these values and compare which
values have best tracking performance.
