## Description

Make some noise, Hero hears everything! Build a unique sound-sensing robot from over 100 parts and learn about engineering and sound technology as you play and experiment with your six-legged robot friend. Thanks to its three directional microphones, Hero perceives and reacts to sounds, allowing you to control it by clapping your hands, snapping your fingers, playing music, or using the included castanet. Activate Hero to follow you around, respond to specific series of sounds, join you in a dance party, or even challenge you to a wild game of tug-of-war! With four different play modes, Hero provides hours of open-ended play and exploration. Hero's innovative design includes movable arms that disappear into its spherical body and a giant, illuminated eye for making facial expressions. The full-color, 52-page manual guides you through step-by-step assembly and includes a comic-book-style story about your new robot companion!

Review: Nice-looking and adorably stem toy - The robot is very cute. We assembled it with my 9-year old son, and it was much fun. We could not figure out at the beginning, how different modes work, but in the end it worked and my son spend several hours playing with it! The plastic is sturdy and high quality, the instruction are well written. Would definitely recommend!
Review: Decent quality, educational, satisfying, inspiring - Great. Slight issue with one of the axes of motion, but was fun to build with my 5 yo (although I admit I did do most of it!). I'm not gonna say it's the most impressive interactive robot, but my expectations weren't too high. We took care when building it, and the fact that it's almost all plastic doesn't matter.

### ⭐ Don't buy
*by J***E on 20 June 2026*

Not well made. Surprisingly difficult, and a bit annoying. Once we finally built it, things just broke or weren't functioning.
