We're not big on store bought kits here at Techsplorers but NXT Mindstorm systems are by no means paint by numbers!
There are some Lego courses that we are adapting from our Duke Techtronics curriculum over to the Techsplorers format. In the introductory course, Techsplorers attempt to design and program a robot to escape confinment by searching around for the exit opening. The more advanced course requires your robot to navigate through a field of unexpected obstacles that simulate terrain on the surface of the planet Mars!
