Sound localization is an extremely exciting topic.

(...) Robolab comes with the RCX firmware and I agree it will probably be a lot easier to grasp for your son than NXC/NBC. The advantage of the latter though is that it is completely free. Since you have a serial tower you'll need to load whatever (...) (17 years ago, 24-Oct-08, to lugnet.robotics)

Hi! I have tried to get my old (old? It was the first one in Austria!) RCX 1.0 working again, but didn't succeed. After all these years, the firmware seems to be gone, it doesn't even run the on-board programs... I tried to install the original (...) (17 years ago, 22-Oct-08, to lugnet.robotics)
