Engino コーディングラボ ERP PRO 2.0（9歳以上向け、2ロボットモデル）

My 10-year-old built the first robot in one afternoon and immediately started tweaking the code to make it walk faster. The controller is surprisingly capable for a kit this size, and the building instructions were clear enough that he only needed help once.

The controller actually holds a program after you unplug it from the tablet, which surprised me since cheaper kits usually reset every time. My son rebuilt the walking model into the second design in one afternoon and spent the rest of the weekend tweaking its speed.

The ERP PRO controller made programming way less intimidating for my 9-year-old than I expected, and he had the first robot rolling within an afternoon. Building the second model took longer since some of the pins fit tight, but honestly that just kept him focused instead of bored.
