Exoskeletons aren't just for shipyard workers or people with limited mobility. If Lowe's has its way, they'll help store staff fetch your giant bucket of paint. The home improvement retailer has partnered with Virginia Tech to test prototype passive exoskeletons that make it easier to haul heavy objects. Carbon fiber in the suits' back and legs serves as a "taut bow" that stores energy when you bend down -- that energy comes back the moment you stand back up, making it much easier to lift that heavy bag of concrete. The material's flexible nature should also help the suits feel relatively comfortable... a rather important consideration for warehouse workers who may need to wear it for an entire shift.
