Learning how to build and program your own robots with the most popular open source robotics programming framework About This Book Get to know the fundamentals of ROS and apply its concepts to real examples Learn how to write robotics applications without getting bogged down in hardware problems Learn to implement best practices in ROS development Who This Book Is For This book is for robotic enthusiasts, researchers and professional robotics engineers who would like to build robot applications using ROS. It gives the robotics beginner and the ROS newbie an immensely practical introduction to robot building and robotics application coding. Basic knowledge of GNU/Linux and the ability to write simple applications is assumed, but no robotics knowledge, practical or theoretical, is needed. What You Will Learn Control a robot without requiring a PhD in robotics Simulate and control a robot arm Control a flying robot Send your robot on an independent mission Learning how to control your own robots with external devices Program applications running on your robot Extend ROS itself Extend ROS with the MATLAB Robotics System Toolbox In Detail ROS is a robust robotics framework that works regardless of hardware architecture or hardware origin. It standardizes most layers of robotics functionality from device drivers to process control and message passing to software package management. But apart from just plain functionality, ROS is a great platform to learn about robotics itself and to simulate, as well as actually build, your first robots. This does not mean that ROS is a platform for students and other beginners; on the contrary, ROS is used all over the robotics industry to implement flying, walking and diving robots, yet implementation is always straightforward, and never dependent on the hardware itself. ROS Robotics has been the standard introduction to ROS for potential professionals and hobbyists alike since the original edition came out; the second edition adds a gradual introduction to all the goodness available with the Kinetic Kame release. By providing you with step-by-step examples including manipulator arms and flying robots, the authors introduce you to the new features. The book is intensely practical, with space given to theory only when absolutely necessary. By the end of this book, you will have hands-on experience on controlling robots with the best possible framework. Style and approach ROS Robotics By Example, Second Edition gives the robotics beginner as well as the ROS newbie an immensely practical introduction to robot building and robotics application coding. ROS translates as "robot operating system"; you will learn how to control a robot via devices and configuration files, but you will also learn how to write robot applications on the foundation of this operating system.

The acclaimed and captivating true story of two restless society girls who left their affluent lives to “rough it” as teachers in the wilds of Colorado in 1916. In the summer of 1916, Dorothy Woodruff and Rosamond Underwood, bored by society luncheons, charity work, and the effete men who courted them, left their families in Auburn, New York, to teach school in the wilds of northwestern Colorado. They lived with a family of homesteaders in the Elkhead Mountains and rode to school on horseback, often in blinding blizzards. Their students walked or skied, in tattered clothes and shoes tied together with string. The young cattle rancher who had lured them west, Ferry Carpenter, had promised them the adventure of a lifetime. He hadn’t let on that they would be considered dazzling prospective brides for the locals. Nearly a hundred years later, Dorothy Wickenden, the granddaughter of Dorothy Woodruff, found the teachers’ buoyant letters home, which captured the voices of the pioneer women, the children, and other unforgettable people the women got to know. In reconstructing their journey, Wickenden has created an exhilarating saga about two intrepid women and the “settling up” of the West.

A perfect and irresistible idea: A cookbook filled with delicious, healthful recipes created for everyone on a tight budget. While studying food policy as a master’s candidate at NYU, Leanne Brown asked a simple yet critical question: How well can a person eat on the $4 a day given by SNAP, the U.S. government’s Supplemental Nutrition Assistance Program informally known as food stamps? The answer is surprisingly well: Broiled Tilapia with Lime, Spicy Pulled Pork, Green Chile and Cheddar Quesadillas, Vegetable Jambalaya, Beet and Chickpea Salad—even desserts like Coconut Chocolate Cookies and Peach Coffee Cake. In addition to creating nutritious recipes that maximize every ingredient and use economical cooking methods, Ms. Brown gives tips on shopping; on creating pantry basics; on mastering certain staples—pizza dough, flour tortillas—and saucy extras that make everything taste better, like spice oil and tzatziki; and how to make fundamentally smart, healthful food choices. The idea for Good and Cheap is already proving itself. The author launched a Kickstarter campaign to self-publish and fund the buy one/give one model. Hundreds of thousands of viewers watched her video and donated $145,000, and national media are paying attention. Even high-profile chefs and food writers have taken note—like Mark Bittman, who retweeted the link to the campaign; Francis Lam, who called it “Terrific!”; and Michael Pollan, who cited it as a “cool kickstarter.” In the same way that TOMS turned inexpensive, stylish shoes into a larger do-good movement, Good and Cheap is poised to become a cookbook that every food lover with a conscience will embrace.

The stories are all told by the author in the first person, typically addressing a Parisian reader. The author, having relocated his home from Paris, recounts short bucolic tales about his new life in Provence as well as his trips to Corsica and French Algeria. Considered to be light-hearted, and often a bit tongue-in-cheek, the stories vary from day-to-day events in southern France to Provençal folk-tales, and often feature professions and faunal references characteristic of Provence.
