This robot looks like from a Sci-Fi movie but hey - you can buy it for 315.000 US$ and it works... What ever you'll do with it... Because it is a suite you maybe feel more safe in the streets?

The Land Walker was made by Masaaki Nagumo, measures 11 feet tall, weighs one ton, and sprays bullets from air guns mounted outside the cockpit. Unfortunately they're only sponge bullets, but I bet it'll still hurt like a bitch when you spray your friends with them.
