Say "hello" to our future robot overlords.
This is the Kid's Walker Cyclops, developed by Japanese robotic manufacturer Sakakibara-Kikai. It's an updated version of another kiddy mech-robot that the company released a few years back, but with some snazzy upgraded features. It's a neon green robotic-exoskeleton that comes with a claw and spinning drill, and moves around on wheels placed on the bottom of its feet—it's just a step away from looking like something out of Gears of War or MechWarrior. The last version of the Walker Cyclops was priced at $20,000, so "expensive" is a keyword here. But they are available for rent, if you want to traumatize any and all kids on your block.
