We've built robots that can navigate on land; now let's look at the possibilities for building robots that can navigate in the air or on the water. By now I hope you are comfortable accessing the USB control channels and talking with servo controllers and other devices that can communicate over USB. Instead of leading you through each step, in this chapter I'm going to point you in the right direction and allow you to explore a bit. I'll try to give you some examples using some of the projects that are going on around the Internet. I hope you are now ready to explore a bit on your own, for these projects can be quite complex and I'm not going to lead you through each step.
You don't want to limit your robotic possibilities to just walking or rolling. You'll want your robot to fly, or sail, or swim. In this chapter, you'll see how you can use the capabilities you have already mastered in projects that defy gravity, explore the open sea, or navigate below...
