That's a bold claim, but it's hardly far-fetched. Right now, taking inventory of a Walmart warehouse means having a team of workers manually scan stock by hand -- slowly using forklifts and ladders to reach higher shelved products. The drone, on the other hand, can quickly sweep isles with a high speed camera, snapping as many as 30 images per second. If Walmart's test proves the program to be reliable, it could save the company millions. That said, it'll be a little while before that's a reality: testing is expected to continue for another 6-9 months.
