#3 Transforming LEGO Apple Power Mac G4 Cube – video #3, Autonomous mode

This video demonstrates the “Transforming LEGO Apple Power Mac G4 Cube” in autonomous mode.

What’s happening in this video:

1. The original Apple iMac G4’s loud startup chime activates the cube’s sound sensor which begins the pre-programmed routine.

2. The light sensor’s ambient light source (red LED) illuminates the G4 cube’s Apple logo.

3. “Interactive Servo Motor A” lowers the wheeled mobile unit and relies on the servo motor’s built-in rotation sensor for when to stop.

4. Motors B and C provide directional movement and relies on the rear mounted ultrasonic sensor to avoid a collision with the LEGO R2-D2 crossing in front of it.

5. When the ultrasonic sensor detects that the cube has reached the wall, both motors B and C stop and motor A raises the wheeled motor unit and stops when the touch sensor is pressed.

6. The light sensor’s ambient light source stops generating light.

Recently purchased a used Power Mac G4 Cube.

This creation utilizes all of the default electronics from a LEGO Mindstorms NXT set. Crammed into the Apple Power Mac G4’s famous “8-inch” (acrylic) cube are a LEGO NXT programmable brick, 3 interactive servo motors and all 4 sensors: touch, sound, light, and ultrasonic. It can operate in 2 modes:

1. Autonomous mode – relying on its sensors to interact with its environment
2. BlueTooth remote controlled mode
