 | | Identify a zig
|
| So, I was looking at the Chibots Advanced Line Following course. BTW, they are using the same course as last time. If you want to see it, you can go to their web site ((URL) go to events, and watch at the May '05 video. The pictures posted are from (...) (19 years ago, 11-Oct-05, to lugnet.org.us.laflrc)

| (...) Steve, Well you know how bad I am at programming and all, but my first thought on this was something like this... light sensor (LS)1 goes black then LS! & LS@ go black then LS1, LS2, and LS3 go black (depending on thickness and orientation of (...)

| (...) Probably, but (a) the organizers have said they would use the same course, (b) the "zig zag" portion is a very specific barrier. While memorizing the course ahead of time might not be the intent, in the event description they encourage folks (...) (19 years ago, 11-Oct-05, to lugnet.org.us.laflrc)

| (...) Actually, I think if someone could design a robot that would "appear" to follow a memorized line, that would be encouraged, because it's all about advancing robotics. However, wouldn't that be like going though a line-maze, without looking at (...) (19 years ago, 11-Oct-05, to lugnet.org.us.laflrc)

| (...) 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 (19 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 (...) (19 years ago, 11-Oct-05, to lugnet.org.us.laflrc)
| | | | | Re: Identify a zig

| (...) 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 (...) (19 years ago, 11-Oct-05, to lugnet.org.us.laflrc)

| (...) 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 (19 years ago, 11-Oct-05, to lugnet.org.us.laflrc)

| (...) Actually, the sensors are a pretty flat V. But, how can you tell if (A) you passed a zig in the road or (B) you passed a somewhat sharp turn? Steve (19 years ago, 12-Oct-05, to lugnet.org.us.laflrc)
