## Overview

Designed for kids 8+ (with help) or 12+ independently, Hero offers four interactive play modes—follow, respond to sound patterns, dance, and tug-of-war—while teaching engineering, sound technology, and spatial hearing. The kit includes over 100 parts, a 52-page illustrated manual, and customizable stickers, making it an award-winning educational toy that blends hands-on STEM learning with creative, engaging play.

## 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: Kids enjoyed it - Great project for the kids. They had a blast building it. Quality isn’t there but I was going more for quality time with my son so it’s great.
Review: Worthless piece of junk - Very disappointed. I got it as a Christmas present for my robot-obsessed son, but after hours of work putting it together, all it did was shake a bit and make noises while the legs popped off. I thought maybe my son had messed something up, so I rebuilt the legs (being super careful about the pieces, because the tabs are small and VERY delicate), but nope, no difference. So finally I tore the whole thing apart, thinking maybe something was wrong with the gear assembly--and again, after carefully reassembling the stupid thing, still just shaking in place. Now the piece of junk is in the trash and I'm here writing this review just to complain about the hours of my life wasted for nothing.
