The Land Walker exoskeleton is a product of Japanese company sakakibara-kikai. Used mainly for product promotion and display, the intimidating weaponry fires nothing but harmless soft plastic balls. And with a top speed of just 1mph it’s not going to replace the wheel just yet.

However, standing over 3 metres in height, and weighing in at 1000kg (2,205 lbs) the Land Walker’s shuffling gait is an impressive sight to behold. Although it would probably run into problems with anything but a completely smooth surface.
