| | | (...) I'll chime in here (I lurk way too much): Given the choice, I'd like to see included in NXT a software module for coding dead-reckoning navigation for turtle-type robots, kind of like here: (URL) since the NXT motors have built-in encoders, (...)

Possibly even two microphones to try to estimate the direction the sound is coming from. Would be cool for Sumo competitions. Although, (...) (19 years ago, 22-Feb-06, to lugnet.robotics)

| | | | (...) 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)

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 (...)
