Chapter 2. Building the Biped
Now that you've got your Raspberry Pi 2 Model B all configured and ready to go, you'll need to add some hardware to control and interface. In this chapter, you'll learn:
- How to build a basic 10 Degrees of Freedom (DOF) biped
- How to use a servo motor controller connected to the USB port of the Raspberry Pi to control the servos to make your robot move
Building robots that can walk
There are several choices when considering how to create a mobile robot. One of the more interesting choices is a robot that can walk. This normally comes in three versions: a biped robot with two legs, a biped robot with four legs, and a hexapod robot with six legs. While each offers an interesting and different set of possibilities, in this chapter, you'll build a basic, 10 DOF biped.
You'll be using a total of 10 servos for your project, as each leg has 5 points that can move, or 5 degrees of freedom (DOF). As servos are the most critical component...
