The online British grocery store Ocado recently unveiled their newest employees – over one hundred robots, all working to stock, package and pick up groceries.

The scene looks like something that might emerge if a science-fiction film were set in a warehouse, with a hive of automated robots scuttling to and fro, collecting and filling crates in response to orders received online, so that they can be despatched to the buyer.

According to Business Insider, these robots can pack 65,000 grocery orders every week, have a top speed of 4 metres per second, and are battery-operated. It’s impressive, but also worrying, considering these are jobs that were once held by humans.
