Defend yourselfâ€”and your planetâ€”against the onslaught of evil at your door. It goes without saying that robots kill. They hunt, swarm, and fire lasers from their eyes. They even beat humans at chess. So who better to stand with us when the real villains arrive? Movies instruct us that, whether we like it or not, we will one day be under siege by pirates, ninjas, zombies, aliens, and Godzilla. Also great white sharks. Andâ€”letâ€™s face itâ€”weâ€™re not prepared. But with the advice contained in this brilliantly illustrated, ingenious book, you can build your own robot army to fend off hordes of bloodthirsty foes. From common-sense injunctions (â€śnever approach an unfamiliar robot in a militarized zoneâ€ť) to tactical pointers (â€ślow-power radar beats cameras for detecting mummies in a fog-shrouded cryptâ€ť) to engineering advice (â€śpassive-dynamic exoskeleton suits will increase sprint speeds but not leg strengthâ€ť), this book contains all the wisdom youâ€™ll need to fend off the coming apocalypse. Witty, informative, and utterly original, How to Build a Robot Army is the ideal book for readers of any age.
