Robotics experiments with Rasti Block (Argentine building blocks) -- Arduino, IR remote, DHT sensor

Building robots with Argentine toys. Because innovation doesn't need expensive equipment.

Robotics experiments using Rasti Block -- Argentina's own building block system (similar to LEGO but from Buenos Aires). This project combines Rasti mechanical structures with Arduino microcontrollers, infrared remote control, and environmental sensors to create programmable robots from accessible materials.

In Argentina, LEGO Mindstorms was prohibitively expensive. But Rasti Block -- a local toy brand -- was available and affordable. This project demonstrates a core philosophy: you don't need expensive equipment to learn robotics. You need creativity and the willingness to build with what you have.

This is the same philosophy that built a telescope from old lenses, a hygrometer from human hair, and eventually an autonomous SOC from open-source tools.

• Rasti Block -- Mechanical structure and chassis
• Arduino -- Microcontroller for motor and sensor control
• IR Receiver -- Infrared remote control for robot commands
• DHT Sensor -- Temperature and humidity monitoring

• IRremote Library -- Infrared signal decoding and processing
• DHT Library -- Environmental sensor reading
• Scratch 2.0 Extension (.s2e) -- Visual programming interface for younger users

A kid in Villaguay couldn't afford LEGO Mindstorms.
So he used Rasti Block -- Argentine building blocks.
Added an Arduino, some sensors, an IR remote.

Same robot. Different bricks.
Same learning. Different price tag.

That's the whole point:
Innovation doesn't require expensive equipment.
It requires curiosity and the courage to build
with whatever you have.
