How PrimaSTEM works
1
Place tokens left to right. Green LED = accepted. The board speaks the command.
2
Press "Start." The robot executes. LEDs show which command is running.
3
Check the result. Wrong? Find the error, swap a token, run again.

Works with any map
Step size is adjustable. 10, 12, 15, 25 cm — any grid. Use maps from any robot already in your classroom. No new materials needed.
Open platform
Every token is a standard NFC tag (13.56 MHz). Write any code using a free phone app. Create your own numbers, loops or arithmetic operations.
NFC tags on the playing field — the robot plays audio when it drives over them. Language cards, musical fields, story quests.
Voice feedback
The board speaks each token as it's placed. Helps children who can't read yet and children with visual impairments.
Braille version in pilot testing.
