As others pointed out... it's a robot arm to move the cup from the full-auto espresso machine to the vending window. Completely pointless given there are coffee vending machines that are already much better than those full-auto espresso machines... (of course... it's not completely pointless... some people will prefer to buy the coffee from the robot arm once for the novelty... and coffee vending machines have negative stigma associated with them, even though the best ones are actually really good)
