I worked on a robotics project in which my program controlled a very big (18,000 pounds) piece of equipment and need to know its position. It was used for railroad track maintenance and road on the tracks. Even though this was a one dimensional (...) (24 years ago, 11-Jan-01, to lugnet.robotics.rcx.nqc)

I've just released the first beta version of Visual NQC 2001. This a program that is based on RCX Command Center but is programmed in Microsoft Visual Basic 6.

(...) I have seen a nonlego robot called Cye. He is controlled by a human on a computer. As you move him about a room, he uses a computer program and a bump sensor to make a 'map' of the room. After the map is made, a homebase can be set up, and (...) (24 years ago, 3-Jan-01, to lugnet.robotics.rcx.nqc)

THE QUESTION ... ... how to determine and measure a position in a room? This question was raised several times in LUGNET (e.g. Kris Zabriskie) and caused some discussions.

Thanks to everyone who helped out with my problem, it's much appreciated! The problem was not having the firmware loaded, which I was able to download to the RCX using the latest version of MacNQC.
