Our first climb and dump of the season!

Thanks for reminding me... We still need to put the camera on the robot! It'll be pointing straight up to help us align with the tower. Yes, that certainly is a concern, but we have room to spare - our practice tower here is a little small, all the way up. One of the issues we had tonight was getting stuck climbing... by the bumpers rubbing against the uprights!

Oh, and two more notes... with the exceptions of a safety trigger (if we release, all motion immediately stops) and a manual button for the dumper, the entire sequence (once lined up) is completely automated. Also, the dumper should be able to dump into the low goal, but we haven't built one as it wasn't a priority. Maybe we'll check that out in Duluth

How long do you think (once your drivers are practiced and you have the routine down) to go from lined up to climbed to the top and frisbees scored?

That is the big question for us as well. Tonight, we saw a climb taking about 40 seconds to the top. There are 2 seconds of "pause" built in at each level so we could check the hooks and stop if needed (4 seconds total), plus another 5-10 seconds we should be able to salvage with PID tuning (up to 9-14 seconds), and another 2 seconds per level once we get the limit switch issue fixed (13-18 seconds). The dump should take 1-2 seconds, once we get the chain jumping issue fixed.

We'll be happy with 30 seconds from floor to 50 points, but we're hoping for 20 We're going to double the power we have on the winch (we had 1 Mini-CIM, we're adding a second), which should help as well... we were really taxing the Mini-CIM to climb that high, and after 2 hours straight of climbing it was hot enough to fry an egg!

Fastest climb I've seen to date. What do you plan on doing the other minute and a half of the match? (or is it a team secret? )

Honestly, I don't know what the team plans. We'll be able to dump in the low goal (just back in and dump it over the arm with the same motion you saw in the video), so we could score a few points that way. Personally, I think the best bet is to get our 4 colored discs and try to disrupt the flow of scoring for the opposite alliance until we need to climb. We're too low to block most shooters, but we can do some pushing, and prevent/delay robots from traversing the field (assuming they can't shoot full court).
