Johnco: 14 in 1 教育用ソーラーロボット

The two-level building system is perfect for pacing my kid—he started with the simpler models and now tackles the harder ones on his own. Watching it crawl across the table powered purely by sunlight still feels like magic every time.

My 8-year-old has built four of the 14 models so far, and the two difficulty levels keep him challenged without getting frustrated. The fact that it runs purely on sunlight means no batteries to buy, which is a huge win for me.

The solar panel actually works indoors near a bright window, which surprised me. My kid spent hours switching between the different robot builds.
