Your next robot encounter - dinner, drinks and a massage

Collaborative robots that work alongside humans -- "cobots" -- are getting cheaper and easier to program. That is encouraging businesses to put them to work at new tasks in bars, restaurants and clinics. In the Netherlands, a cobot scales a 26-foot-high bar to tap bottles of homemade gin, whiskey and limoncello so that bartenders don't need to climb ladders. In Singapore, robots give soft-tissue massages. Cobots made up just 5% of the $14 billion industrial-robot market in 2017, according to research by Minneapolis-based venture-capital firm Loup Ventures.
