Things have been way too quiet on here for a long time now...
Since I know I won't be getting much LEGO playing time at home anytime soon, and
since I was headed out of town this past weekend, I took a page from Dave K's
book and took my LEGO with me. I took my recently arrived retail NXT kit and my
prototype with the idea of working out the BT remote control functionality. I
actually managed to get it to work rather quickly. I was amazed at how easy it
was to create a reciever and transmitter program. But I've got a few questions
for those of you who've done this sort of thing before.
1. A "dead" spot in the center. As it stands now, it is very tough to get the
transmitter back to "0" so the motors on the receiver NXT actually stop. Is
there an easy way to create a larger "stop" zone?
2. This may be related to #1... I think I remember at HoB how at least one
remote was auto-centering. How was that done? Is it just a matter of
continuously driving the levers back to 0 degrees at a low power setting?

| (...) I have mine set so if the reading is between -10 to +10, it stops. So, if the reading is <-10, go backwards, else if the reading is >+10 go forwards, else stop. (...) This is a bit tricky. And, a bit of trickery. The program is very simple. (...) (18 years ago, 31-Jul-06, to lugnet.org.us.laflrc)
