Humans have been making butter for thousands of years. If you have a cooperative cow or sheep and a means to agitate her milk, butter is not far behind. So why would you employ a $15,000 industrial robot to make butter? Because – robot butter!
Actually, Robutter is a design experiment by [Stephan], [Philipp], and [Jonas] to explore where craft ends and industrial processes begin, and to see how automation adds or removes values from traditional products. It’s a fair question, given that butter can be churned with everything from animal skins to massive continuous churns. So the team programmed [DIRK], a Fanuc LR Mate 200ic which is normally more at home on an assembly line, to carefully agitate a container of cream. After a bit of fiddling they found the optimal position and movements to produce a delicate butter that looks pretty tasty. The video after the break shows the process and the results, but sadly there’s no taste test of the Robutter against grocery store butter.
It may come as a surprise that Hackaday appears never to have featured a butter making project before. Sure, we’ve got a lot of food hacks, most of which seem to involve beer or coffee. But we did run across a recent article on a buttermilk pancake-making robot that you might like to check out.
