introduction The LEGO BOOST set 17101 is called a Creative Toolbox for a reason Its large assortment of LEGO elements and electronic devices allows you to bring your LEGO creation to life The BOOST set and its companion app were designed to teach programming and robotics to kids with a smooth learning curve With LEGO BOOST you can build and program your own robots or boost any of the LEGO models you already have by adding motors and sensors to them why this book Coding has become a buzzword in schools around the world because programming programming is considered a fundamental skill of the 21st century Exploring robotics with LEGO BOOST is a great way to introduce programming to kids of all ages even young ones Although the LEGO BOOST set includes ready-made programming blocks that allow you to do complex things there’s no manual in the box to show you how to get started or to create and program your own robots from scratch That’s where this book comes in The LEGO BOOST Activity Book uses a fun hands-on approach to introduce you to the LEGO BOOST set and teaches you how to use it to build and program your own robots It covers how the BOOST set works general LEGO building techniques and thoroughly introduces you to robot programming in a way that you won’t find inside your BOOST set by itself You’ll learn how to use the BOOST app’s programming blocks to program your own creations You’ll also find building instructions for three different robots xv
