Green Science - 3合1迷你太陽能機器人

The gearbox was surprisingly easy for my nephew to assemble, and he loved watching it walk on the table. Switching between the rope climbing and racer modes kept him busy for hours. It's a solid little kit for the price.

My kids and I spent a whole afternoon switching it between the rope-climbing mode and the racer, and the gearbox cover snaps on securely enough for rough handling. It's genuinely compact but does three different things, which is way more than I expected for the price.

Took it out on a sunny afternoon and the little racer mode actually kept up with my kid’s toy car on the driveway. The rope-climbing trick is a nice touch, though it needs direct sun to really get moving.
