Raspberry Pi is a UK Non Profit with the goal of creating a new generation of computer programmers. Observing how the UK Tech Industry was kickstarted by the availability in the 1980s of relatively cheap, very programmable computers such as the ZX81, the Commodore and the BBC Micro, the Raspberry Pi Foundation designed a £15/$25 computer which encourages the user to play and to learn. Although intended for schools, it has also been adopted by hackers and geeks, and a whole ecosystem of software and hardware is being built around the Pi. With a million boards now sold, the goal of the Foundation is well underway.

BeagleBone Robotic Projects

Overview
  • Get to grips with robotic systems
  • Communicate with your robot and teach it to detect and respond to its environment
  • Develop walking, rolling, swimming, and flying robots
In Detail

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.
