So I took off my nice, compact light sensor, and had to invent a (...) (19 years ago, 23-Dec-05, to lugnet.org.us.laflrc)

| | | | | (...) Hmm..how strange...my T3 robot uses a light sensor to find the blocks and I am having no trouble at all distinguishing all the information I am after. I think I am getting a light delta of around 20 or 30. That seems to be plenty. But, I am (...) (19 years ago, 31-Dec-05, to lugnet.org.us.laflrc, FTX)

| | | | | | (...) Why would you think that's strange? That's the normal difference you'd get between black and white. While John and Brian are pointing their light sensor at the cube/square to check for one of three states (black cube/white cube/no cube) you're (...)

| | | | | | | (...) Thanks Steve - I really wasn't trying to share that much :) ...John had the chance to see the first cut at the mechanism when you guys were here. Obviously, you put 2 and 2 together. And how is your T3 robot doing? B (19 years ago, 31-Dec-05, to lugnet.org.us.laflrc)

| | | | | | | (...) I've been working on mine for the last couple days. I've been having a problem, but I finally figured out I have a rotation sensor that's going bad. It's done a few different things. At one point, it counted from 0 to 24 (when moving across (...) (19 years ago, 31-Dec-05, to lugnet.org.us.laflrc)

| | | | | | | (...) I know how that goes...I just got back the stuff I loaned to the FLL Teams. (...) What about total sensors? How many of each type did you end up using? I forgot to mention in my earlier post that I am also using 2 polarity switches and a (...) (19 years ago, 31-Dec-05, to lugnet.org.us.laflrc)

| | | | | | | | | | | | | | | | Re: 3T —Brian Davis
| | | | | | | (...) Well, just for comparision, mine uses three touch sensors, two light sensors, three motors and one RCX... And doesn't have a prayer of matching a 4 sec move. As it is, if I add another parallel task it fails to accurately register positions, (...) (19 years ago, 31-Dec-05, to lugnet.org.us.laflrc)
| | | | | | | | | | | | | | | | Re: 3T —Bryan Bonahoom
| | | | | | | (...) Well - I actually timed my robot this afternoon. The average move is actually 5 seconds...and, it may be a little longer before I am done as I might put some "dancing" in the mechanism to ensure the cube is properly deposited. We'll just have (...)

| | | | | | | | | | | | | | Re: 3T —Brian Davis
| | | | | (...) Well, sort of. You seem to be using a light sensor to read a mechanical system, not observe the blocks themselves <grin>. And, as my post implied, I ended up with a mechanical system. It's just it doesn't allow all the fun stuff I wanted it to (...) (19 years ago, 1-Jan-06, to lugnet.org.us.laflrc, FTX)

| | | | | (...) All of them :) Not sure on the total count, but it is something like 14 4 stud gear racks and 3 of the long gear racks (8 stud??). Two rows of racks for my forward and back motion help keep the robot going perfectly straight (until a cube (...) (19 years ago, 1-Jan-06, to lugnet.org.us.laflrc, FTX)
