A crowing rooster that reacts to light, a seismic alarm, a mini wind turbine, and so much more — with each one powered by one of these principles. Build it, take it apart, rebuild it differently, and see what happens. And since the parts are fully LEGO-compatible, feel free to invent your own designs that aren’t in any manual.

This building set won’t just sit on the shelf. With 201 parts and 110 projects, you’ll build machines that zoom across the room, drill deep down, climb over obstacles on six wheels, or spin an amusement park carousel. Here, electricity turns into motion—and you can see, hear, and control that motion.

Once you finish one model, another eighty ideas are waiting. And after that, your own. This isn’t just about plugging things in — this is real building. You’ll use the parts to assemble three real space machines that move, light up, and make sounds. And then, you drive them. Grab the controller and send your model rolling via a 2.4GHz signal — the exact same principle used by RC cars and real-world remote-controlled machines. No wires, just you and your rover.

And since the parts are fully LEGO-compatible, feel free to build your own space base to go with the rover.

Developing little inventors through play

Teaching kids to create, not just watch

FLEG kit electronic building sets are designed to entertain kids while they learn. Turn hundreds of projects from the worlds of science, motion, and space into your own working models — and since the parts are fully LEGO-compatible, the sky is the limit for your imagination. Instead of passively staring at screens, children get to experiment, discover, and understand how things truly work.
