"Maybe they don't have the aw-factor of baby animals, but robot animals do have quite the wow-factor. This volume in the Mighty Bots series uses four short chapters to introduce a number of robots that have distictly animal-like features. Some are presented as entertaining wonders, like the BionicKangaroo that, well, hops, and AquaJelly, a way-cool robotic jellyfish. Others, though, have serious applications: WildCat, a doggish bot that "might one day chase enemies during war," and SandBot, an 11-inch roach-like gadget that "might be good for spy missions." All the circuity, wiring, and molded plastic dazzles the eyes, and the photos are enlivened by fact circles and fantastic two-page spreads that compare the robot in question with an animal (e.g. WildCat versus a cheetah). It's a slam-dunk of an idea, cogently and efficiently presented."
