حزمة mBot2 Smart World 3-in-1 الإضافية

The robotic arm attachment took my son about two hours to assemble, and now he's obsessed with programming it to stack blocks. Switching between the carrier and surveying robot builds keeps it from getting boring, which was my main worry with add-on kits.

My kid spent a whole rainy Saturday building the surveying robot, and the coding box that came free with it kept him busy the rest of the week. I like that one add-on pack gives three completely different builds instead of just one.

The carrier robot is the one my son keeps rebuilding—it actually hauls small boxes across the floor without tipping over. Three designs in one box means he's gotten weeks of tinkering out of it instead of finishing in an afternoon.
