Discover the science of sound with Hero, an interactive robot that hears and responds to you using three directional microphones. Build Hero from over 100 parts, then explore four play modes where he can locate and follow you, respond to sound commands, or challenge you to a game of tug-of-war using claps or the included castanet. Featuring movable arms and a large illuminated eye that displays expressions, Hero combines hands-on robotics with engaging play. A 52-page, full-colour manual provides step-by-step assembly instructions while introducing the science of sound waves, spatial hearing and how Hero’s impressive hearing technology works.
