With fun projects, tips, instructions, illustrations, and programs, this comprehensive companion to the powerful new Mindstorms NXT kit will help LEGO(R) popularize robotics in the way that the iPod did for digital music. The book focuses on the features of the new NXT programmable brick while exploring all the basic and advanced NXT inputs and outputs. It also examines communication options with other computers and presents a variety of artificial intelligence concepts and a programming tutorial to those new to NXC and NBC, the languages utilized by NXT. Projects include a tic-tac-toe playing robot, a robotic arm that solves puzzles, a security system, and a remote-controlled vehicle.
