Meet Ant-Roach, Otherlab's pneumatic robot that weights 70 pounds and can support 1000 pounds of weight. It's not the most mobile vehicle out there, but when's the last time you were able to deflate a golf cart? Otherlab is also working on other "pneubotic" devices, like prosthetic arms that can lift several hundred pounds. You can read more about these devices at Hizook.
