Edgar Wright was nice enough to share this one: The Mantis Hexapod - 2.2 litre turbo diesel powered, 5 meter diameter 1900kg walking machine.

"This 2.2-litre Turbo Diesel-powered, British-designed and -built walking machine can be piloted or remote WiFi-controlled, stands 2.8 metres high with a five meter working envelope and weighing in at just under two tonnes."
