BeagleBone Robotic Projects

Overview of this book

Thanks to new, inexpensive microcontrollers, robotics has become far more accessible than it was in the past. These microcontrollers provide a whole new set of capabilities to allow even the most inexperienced users to make amazingly complicated projects. Beaglebone is effectively a small, light, cheap computer in a similar vein to Raspberry Pi and Arduino. It has all of the extensibility of today's desktop machines, but without the bulk, expense, or noise. This project guide provides step-by-step instructions to allow anyone to use this new, low cost platform in some fascinating robotics projects. By the time you are finished, your projects will be able to see, speak, listen, detect their surroundings, and move in a variety of amazing ways. The book begins with unpacking and powering up the components.This will include guidance on what to purchase and how to connect it all successfully–and a primer on programming the BeagleBone Black. Chapter by chapter, we will add additional software functionality available from the open source community, including how to make the system see using a webcam, how to hear using a microphone, and how to speak using a speaker. We then add hardware to make your robots move–including wheeled and legged examples–as well as covering how to add sonar sensors to avoid or find objects, plus wireless control to make your robot truly autonomous. Adding GPS allows the robot to find itself. Finally the book covers how to integrate all of this functionality so that it can all work together, before developing the most impressive robotics projects: those that can sail, fly, and explore underwater.

Mission briefing


We've covered creating robots using a wheeled/track base. In this chapter, you will be introduced to some of the basics of servo motors and using the BeagleBone Black to control the speed and direction of your legged platform. Here is an image of a finished project:

Why is it awesome?

Even though you've learned to make your robot mobile by adding wheels or tracks, this mobile platform will only work well on smooth, flat surfaces. Often, you'll want your robot to work in environments where it is not smooth or flat; perhaps, you'll even want your robot to go upstairs or over curbs. In this chapter, you'll learn how to attach your board, both mechanically and electrically, to a platform with legs, so your projects can be mobile in many more environments. Robots that can walk: what could be more amazing than that?

Your objectives

In this chapter, you will learn:

  • Connecting the BeagleBone Black to a mobile platform using a servo controller

  • Creating a program in Linux to control the...
