Programming level 1
Puppet show
P1
How to build
The robots
- The dog, pear tree, fountain are DC motorised devices powered directly by a battery holder.
- The oven door can be opened axially.
- Construction of father, mother and two daughters – their arms can be moved by axle

Stations on the road
P2
How to build
The robots
- Build stations connected to one motherboard:
- the dog, whose ears can be moved by a servomotor,
- the pear tree and the well are built in a similar way as in P1, but the motors are connected to a programmable motherboard, the well is equipped with a blue LED
- the furnace is equipped with a servomotor with an opening door and a red LED.
- On the first press the furnace door opens and the red LED turns on, the well lowers and then the bucket rises and the blue LED turns off, on the third press the pear tree crowns with gears and rack and pinion, on the fourth press the dog flips its ears back and starts barking with a buzzer.
- The lazy girl moves from station to station as a robot controlled by 4-Touch sensor.

Cooperative robots
P3
How to build
The robots
- The figures in the stations are built in a similar way as in P2, but each figure has 1 IR Photoreflector that detects when the girl has reached it, and then the movement of that figure is triggered (the dog moves its ears, the leaves in the tree start to turn, the bucket in the well lowers and rises and the blue LED turns on, the red LED in the oven goes out and the door opens)
- The lazy girl is equipped with 2 IR Photoreflectors and a Touch sensor
- One IR Photoreflector is used to track and the other to detect the figures at the different stations. When it detects the figures, it stops and starts again when the Touch sensor is pressed, continuing to follow the line.

Line counter robot
P4
How to build
The robots
- The figures on the stations are constructed as in P3
- The girl’s path is marked by black lines glued to the table: the robot counts (with an IR Photoreflector) the number of lines it crosses and then depends on the direction it moves to the next line (these directions are determined by the children)
- The stations are detected by IR Photoreflector in the same way as in P3 and move on by pressing a Touch sensor
- After the second push of the button, the line count starts again from the beginning
