Volume 55 shows you how to build an adorable, 3D-printed balancing bot, how to assemble a Strandbeest-style walker with Lego, and how to find the right robot kit for your needs with our handy overview of what is on the market today. Plus, learn programming by playing with robots, and get started with a shared operating system designed specifically for robotic projects.
