I'm getting back into Mindstorms after a long hiatus. Let me resurrect this old thread, to see what the answer is in 2010. :-) What text-based languages are most mature and best-supported these days for programming RCX and NXT? Is RobotC still (...) (14 years ago, 28-Aug-10, to lugnet.robotics.nxt)
