| (...) If it's any help, my first line-following event (NEIRG, with up to 135° sharp turns) I resolved to start from scratch and "be original". By event day, I ended up with Ben Hur's little brother quite unintentionally. But it worked. (...) Yes, (...) (21 years ago, 12-Oct-05, to lugnet.org.us.laflrc, FTX)

Gee - funny you should ask :) Since none of my ideas were going to look real original any more after playing around at your house last weekend, I resolved to make the rack & pinion approach work better. So, I redesigned the drive train and (...) (21 years ago, 12-Oct-05, to lugnet.org.us.laflrc, FTX)

| (...) consider it a favour returned from my DCC post. as to your problem... blow off your straigh line of 7 sensors, and instead, angle them to make a V then look for center point of V and most others on one side to "fire" Chris (21 years ago, 11-Oct-05, to lugnet.org.us.laflrc)

With my current program, I really can't treat it like a broken line, because it's NOT a broken line. :) As long as the line is under the row of seven light sensors, the robot knows how it needs to adjust. When it passes an intersection, the (...) (21 years ago, 11-Oct-05, to lugnet.org.us.laflrc)
| | | | | Re: Identify a zig
|
| (...) Could you treat it as a broken line? That is, only 'see' the part of the line that is on a straight path through the zigzag. I assume you have to program the robot to ignore the cross line of the loop in the course pictured: (URL) the (...) (21 years ago, 11-Oct-05, to lugnet.org.us.laflrc)
| | | | | Re: Identify a zig
|
| (...) True, but this is not what I was thinking of. If you could follow the line, and correlate it with the map you have, you could realize that you were approaching the zig-zag, and just go straight..... Kev (21 years ago, 11-Oct-05, to lugnet.org.us.laflrc)
