The geographer
Programming level 1
Moving but not yet programmed structure
P1
How to build
The robot
- We build a gear mechanism driven by a DC motor connected directly to a single battery holder.
- The arms of the geographer and the Little Prince can also be moved using axles
- The gears are decorated with elements symbolizing planets, water, and plants
- The structure starts when the battery holder is turned on and stops when it is turned off

Programming level 2
Action indicated by LED
P2
How to build
The robots
- There is 1 LED in the planet built above the figure. The figure is placed on a base plate, which is driven from below by a DC motor that is built horizontally into the robot
- The robot starts automatically when the battery holder is turned on and stops after 3 seconds.

Displaying accelerated movement
P3
How to build
The robots
- The robot’s structure is similar to P2, but with the addition of one infrared sensor.
- The robot starts automatically when the battery holder is turned on, then stops after 3 seconds.
- As the figure passes in front of the infrared sensor, the built-in DC motor rotates faster and faster

Robot activated by infrared sensor
P4
How to build
The robots
- The robot’s structure is similar to that of P3, but with the addition of one infrared sensor
- When the Little Prince stands in front of the infrared sensor, the robot’s program runs similarly to that in P3
