Before you start prepping the bunker for the inevitable robot uprising, do yourself a favour and watch this spectacular blooper reel from the Yizhuang Robot Half-Marathon in Beijing. It’s a sobering—and frankly hilarious—reminder that while bipedal bots have mastered the art of the lab-controlled backflip, a 13-mile trot on public pavement is still a bit of a shambles for anything that’s clearly been skipping leg day. The commentary might be in Chinese, but the universal comedy of a multi-million pound robot face-planting into the tarmac requires absolutely no translation.
