At about 18 kilograms, roughly 40 pounds with its battery included, the As2 is compact enough to move through tight spaces, yet built to handle a standing payload of up to 65 kilograms. That's more than 143 pounds sitting on top of a 40-pound robot, which is genuinely impressive and a little hard to picture until you actually see it in action.
In 2024, the NHS began testing whether flying drones could do a better job than couriers shuttling blood samples between labs in Guy's and St Thomas' hospitals. Instead of weaving through traffic, the drones simply lifted off, crossed central London, and landed minutes later. Delivery times dropped to barely a couple of minutes, reliability shot up thanks to a lack of roadworks in the sky, and the service turned out to be cheaper too. Since then, more than 6,000 samples have been transported by air.
