Connecting the Lego NXT Face Tracker app to your robot:
a. On the main screen of the Android app – click the “Connect” button.
If the Bluetooth icon is red – the robot is not connected. If the Bluetooth icon is blue – the robot is connected.
b. Select the robot from the list of available Bluetooth devices.
Note: Unless you’ve changed, the name should be “NXT”.
If you’ve been asked for a password, the default is 1234. (Unless you’ve changed it from the NXT)
c. When the connection is successful – the Bluetooth icon will turn blue, and the button will be disabled.
d. Insert your Android smart phone into its docking station that you've built;
Making your Lego NXT follow your face:
a. Place your robot on a clear surface like a table. The robot should be facing towards your face;
b. Click on the big Play button on the top of the main screen.
c. Look at your robot till you see your face on the Android’s screen surrounded by a blue frame;
d. The robot will move and correct its position until your face frame in the middle of the screen;
e. Move you pretty face left, right or away from the robot and you'll see how the robot follows you.
f. The robot will NOT stop driving if it hits something on the way, nor stop before falling from the table.
If you are crazy enough to cause this little creature to commit a suicide, you are not deserved for this smart machine!
g. In case that the Bluetooth connection is lost, the robot will not be stopped – you might need to turn it off manually. (appropriate message will be shown)
