I am curious to know why you think you would need to amplify the RCX motor outputs? The Lego motors are very efficient under no load. But the bridge drivers in the RCX seem to cope with the stalled state (about 250mA). Unless you are going to use (...) (26 years ago, 15-Oct-99, to lugnet.robotics)

There may or may not be a free shuttle but my advice is learn the T. Even if you're only in town for a weekend, it's a much better way to go. Plus the trains are much tighter headings than the 1/2 hour heading a shuttle is likely to be on. A cab (...)
