What you're looking at here is Caterpillar's massive D11T bulldozer being operated using a remote control joystick.
It outputs over 900 horsepower, and has an operating weight of over 120 tons. Top speed is just 7.3mph going forward and 8.7mph in reverse, but who cares? It's a freaking bulldozer that works with remote joysticks.
It's like the world's greatest remote-controlled toy - except it's actually designed for moving huge piles of earth in locations too dangerous for human operators.
