'Robot Sommeliers' Live a Life of Luxury

A robot built to drink wine all day? I'm so jealous.

Granted, it's not exactly a robot: It's more of an electronic tongue at this stage. But it's still fantastic at sampling Spain's best wine and differentiating between types.

Created at a university in Barcelona, the tongue features voltammetric sensors that are activated when they bind to sugar molecules. The sensors then send an electronic signal with a particular pattern, which corresponds to each wine type.

For now, the robotic tongue can identify just three types of Spanish wine. Eventually, however, the researchers hope to program and train it to ID all of them. And all the while, all those calories won't mean anything.
