Now that your Galileo can run Linux, you'll need to build a quadruped that has four legs. You'll be using 12 servos so each leg has three points that can move, or three degrees of freedom (DOF). You could use the IDE and its General Purpose Input/Output (GPIO) pins to control a limited number of servos. However, you need to control 12 servos for this project, so this won't work. In this project, you'll use an external servo controller that can supply the control signals and voltages for all 12 servos. This example will also show you how to use the Linux capabilities of the Galileo for even more complex robotics projects.

Since servos are the main component of this project, it is perhaps useful to go through a tutorial on servos and how to control them.
