The LEGO MINDSTORMS EV3 Laboratory: Build, Program, and Experiment with Five Wicked Cool Robots!

Author

Daniele Benedettelli

2014

Book Description

The LEGO® MINDSTORMS® EV3 set offers so many new and exciting features that it can be hard to know where to begin. Without the help of an expert, it could take months of experimentation to learn how to use the advanced mechanisms and numerous programming features.

In The LEGO MINDSTORMS EV3 Laboratory, author Daniele Benedettelli, robotics expert and member of the elite LEGO MINDSTORMS Expert Panel, shows you how to use gears, beams, motors, sensors, and programming blocks to create sophisticated robots that can avoid obstacles, walk on two legs, and even demonstrate autonomous behavior. You'll also dig into related math, engineering, and robotics concepts that will help you create your own amazing robots. Programming experiments throughout will challenge you, while a series of comics and countless illustrations inform the discussion and keep things fun.

As you make your way through the book, you'll build and program five wicked cool robots:

ROV3R, a vehicle you can modify to do things like follow a line, avoid obstacles, and even clean a room
WATCHGOOZ3, a bipedal robot that can be programmed to patrol a room using only the Brick Program App (no computer required!)
SUP3R CAR, a rear-wheel-drive armored car with an ergonomic two-lever remote control
SENTIN3L, a walking tripod that can record and execute color-coded sequences of commands
T-R3X, a fearsome bipedal robot that will find and chase down prey

With The LEGO MINDSTORMS EV3 Laboratory as your guide, you'll become an EV3 master in no time.

LaTeX – Diferencia entre el paquete inputenc y fontenc

Cuando escribimos documentos en español con LaTeX, generalmente, los paquetes inputenc y fontenc van de la mano. Las funciones que realizan estos paquetes son distintas, sin embargo, están relacionadas con los caracteres extendidos imprimibles. Estos caracteres abarcan símbolos como las comillas, letras mayúsculas y minúsculas con acentos, tilde, diéresis, comillas, virgulilla, etc.

El paquete inputenc nos permite introducir, directamente desde el teclado, letras con acentos y otros símbolos en los documentos LaTeX. Los usuarios GNU/Linux usan la codificación utf8, \usepackage[utf8]{inputenc}. Los usuarios de MS Windows usan la codificación latin1, \usepackage[latin1]{inputenc}. Si no se incluye este paquete los caracteres extendidos se tendrían que introducir por medio de comandos de LaTeX, por ejemplo \’a para que imprima á.

El paquete fontenc nos permite seleccionar los caracteres extendidos imprimibles de los documentos generados por LaTeX, es decir, en los archivos PDF. Si no se incluye este paquete los acentos y letras se seleccionan por separado, por ejemplo, á se seleccionaría como ‘a.
