Mantis runs off a 2.2-litre, 50 horsepower turbo diesel engine, and it stands 2.8 meters (9 feet) tall. It can be piloted directly or controlled via wifi. Functionally, it can manipulate objects (like pushing a trailer) or fold itself into a truck bed.
Thankfully, the robot can currently only move at around one kilometer/hour, so it'll be a while before they're chasing people down and stomping them in the streets. "I still want one." I know you do, but as your financial adviser for all things evil genius I have to suggest saving for a secret volcano lair first.
Hit the jump for a couple videos of the thing in action.
Thanks to Mar and jayson, who agree the only way to fight giant hexapod robots are with even GIANTER hexapod robots. This will end badly.
