Dutch inventors unveiled on Monday a 75,000 euro ($111,100) car-fuelling robot they say is the first of its kind, working by registering the car on arrival at the filling station and matching it to a database of fuel cap designs and fuel types. The bot can apparently identify cars as they pull up, and reference them against a database to determine the type of fuel cap and the fuel type to use, which should avoid any mishaps. Somewhat interestingly, the inventors admit that the technology isn't an entirely new idea, and they give credit for the inspiration to the robots used for milking cows, saying that "if a robot can do that then why can't it fill a car tank." While it's apparently not a done deal just yet, the team say they hope to roll out the robot to a "handful" of Dutch gas stations by the end of the year.
