(...) Having given this a bit more thought, the code would be almost the same. Even though the encoders are built-in, there's no guarantee that the motors themselves are matched. You would still need control loops to ensure that the motors rotate at (...) (19 years ago, 22-Feb-06, to lugnet.robotics)

(...) Tim, Just so you know, the people working on the NXT are aware of the problems people often have when trying to make a robot go straight, and they have addressed it. Some day, I'll show you the NXT program to accomplish that challenge. It will (...) (19 years ago, 22-Feb-06, to lugnet.robotics)

(...) The question is just how much of this is handled at what level within the NXT firmware & software. I'd be surprised if LEGO doesn't do *something* with the built-in encoders - after all, *they* put them there. the question is how much. The (...) (19 years ago, 22-Feb-06, to lugnet.robotics)

(...) I'd go further than that - I may be wrong here, but AFAIK professional roboticists largely consider dead reckoning to be a losing game, an amateur red-herring that you can waste all the time and money you want on and it will still never work (...) (19 years ago, 22-Feb-06, to lugnet.robotics)
