They are based upon the Lego Technic range and expand it with programmable or pre-programmed computers as well as sensors and motors. There is also a huge community built around these, both here at OrionRobots, and at Lugnet. Lego have continued to work with the community, and in fact used this resource to help guide the design and testing of the NXT.
The sets are sold through the Lego store online, and in retail stores, as well as in versions designed for classrooms from Dacta.
There are a number of programming systems, both designed by Lego and by the community. Those from Lego include Robolab and RCX Code, and those from the community include NQC, Lejos, BrickOS and plenty more.
|Joe Nagata's Lego Mindstorms Idea Book||Joe Nagata||This has some great ideas, tips and tricks to use with Lego Mindstorms kits.|
|Jim Sato's Lego Mindstorms: the Master's Technique||Jin Sato||It would be almost a crime to mention one of these books without the other. Jin Sato's book is worth buying, even if it is just for his joint tech.|
