How to build

Build with DC motor

  • Gear wheel driven by a DC motor mounted on a battery holder.
  • The head of the nut mounted on the gears is red on one side and white on the other.
  • Luise is holding the plates in her hands on one side and the pots are at her feet on the other side.
  • As the gears turn, the mother and Luise show two parts of the scene.

How to build

Lottie & Mother

  • Luise is a standing robot with her arm attached to her body by a DC motor. 1 sound sensor is attached to her.
  • On shouting, she lowers her arm and the plate falls.
  • The mother is mounted on a trolley. 1 push button is attached to her, her face has 1 red and 1 white LED.
  • Press the push button and she rolls forward while the red LED lights up, then stops and the white LED lights up.

How to build

Lisa

  • The mummy is built as in P2. 2 IR photoreflectors are connected to it.
  • Start it with a push button, it comes in as a tracking robot, stops at a predefined position. The LEDs work as in P2.
  • 1 servo motor is mounted on Luise’s shoulder and neck, and a sound sensor is connected to the robot.
  • A cube in the little girl’s hand represents the plate.
  • She spreads her hands with the servomotor and the plate falls. Her head turns around her neck: Lotte’s head turns into Luise’s head.

How to build

The robots

  • The mother is constructed in a similar way as in P3. We attach an accelerometer, IR photoreflector and buzzer.
  • Accelerometer is used to guide the little girl to the robot, and when the IR photoreflector detects the little girl, it stops, the red LED goes out, the white Led lights up and makes a buzzer sound.
  • The hand of the little girl is fixed to a geared-gear-gear mechanism moved by a DC motor, a servo motor is mounted in the plate.
  • Luise holds the plate in her hand, lowers the plate onto the DC motor geared rack on the sound sensor and the servomotor causes the plate to open as if it were to break in two.
  • Meanwhile, her head turns from Lotte to Luise, as in P3.
