Java is a very good language, but *NOT* a very good choice of language for robot control. Java's greatest strength is its portability, but portable programs in hardware like the RCX, are not likely to accomplish much. (Have you ever tried to write a (...)

I realize there is still ongoing discussion about the "next generation" OS for the RCX, but it appears there are two immovable camps. One camp wants to do the minimum work possible and come up with an incremental upgrade to the existing firmware. (...) (25 years ago, 6-May-99, to lugnet.robotics)
