Figure 5-1. Need a refreshing glass of chocolate milk? Just press a button

For our next project we’re going to build a robot that makes a cup of chocolate milk by mixing together chocolate syrup and regular milk. It’s silly, of course—who needs such a thing? Still, it’s a great opportunity to expand our knowledge of Lego robotics and to introduce a couple of new tools. Plus, everyone loves a treat!

The way the robot works is that it pumps milk from its jug to a beverage cup using an aquarium pump, which pressurizes the jug and makes the milk to squirt out through an outlet tube, which conveniently dispenses into a glass. While the pump moves the milk, a second assembly squeezes a 6-oz. bottle of chocolate syrup while a stirring assembly mixes up the drink. All of this happens at the touch of the button.
