This video demonstrates the “Transforming LEGO Apple Power Mac G4 Cube” in autonomous mode.
What’s happening in this video:
- The cube’s sound sensor is activated by the original Apple iMac G4’s loud startup chime which begins the pre-programmed routine.
- The light sensor’s ambient light source (red LED) illuminates the G4 cube’s Apple logo.
- “Interactive Servo Motor A” lowers the wheeled mobile unit relying on the servo motor’s built-in rotation sensor for a command to stop.
- Both motors B and C provide directional movement and rely on the rear mounted ultrasonic sensor to avoid a collision with the LEGO R2-D2 crossing in front of it.
- When the ultrasonic sensor detects that the cube has reached the wall, both motors B and C stop.
- Motor A raises the wheeled motor unit and stops when the touch sensor hits the Cube’s “ceiling”.
- The light sensor’s ambient light source stops generating light.
