## 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!

### ⭐⭐⭐⭐⭐ Recommended
*by K***R on January 18, 2026*

My son enjoyed building it. It kept him engaged for hours until he finished it.

### ⭐ Hoŕrible
*by M***Y on September 6, 2025*

Horrible product. None of the parts stay in place spent the 2 days with my son trying to get it together just for it to barely move and prices popping apart. Watched the assembly videos many times

### ⭐⭐ So disappointed
*by T***A on March 8, 2025*

It turns on, it makes noises, it moves, it spins but it doesn't move from the spot you put it in or seem to sense sound. All of the legs keep unclipping and two of the legs aren't at the same level so they don't touch the floor. We can hear parts inside moving around and rotating but sometimes the robot itself doesn't move at all. The way some of this is put together is just not secure so I'm not sure if something came undone in the long process of putting it together or if we missed a step. I might take it apart and start at step one to see if there is anything I can do to fix it. It also took SO LONG to put it together. We used the YouTube video they provide a link to to put it together instead of the instructions. The video is about 38 minutes, but it took us so much longer since we had to stop to follow the instructions and put things together. Anyone who buys this is definitely going to need to set a couple of hours aside. Last thing I want to say is an adult should be there during assembly for kids under 10. There are some things that young kids will need help with and they have to be careful to put the pieces in the right way or they could end up with a dud. I gave it 2 stars instead of 1 since it does turn on, light up, and move, but this is such a big disappointment for a kid who loves robots.
