Dusty Roboter-Staubsauger

My 7-year-old spent a whole Saturday building this kit, and the snap-together pieces made it surprisingly easy. Now he programs Dusty to bump into furniture on purpose just to see it change direction — it's actually teaching him logic without him realizing it. Best twenty bucks I've spent on a rainy

My daughter spent a whole Saturday building Dusty from the box, and I was impressed how clearly the step-by-step assembly taught gear mechanics. It actually moves around the room when you're done, which makes all that learning feel like a reward.

My son's been glued to this kit for two afternoons straight, and the way the gears click together when he finally got the chassis moving was so satisfying to watch. It's a solid intro to robotics that doesn't need a screen to hold his attention.
