hey nick //no programming joke needed haha jk

[Nick Lawrence]

Mike,

That was terrible

-Nick

Remember today with the sound effects? That was hilarious!

[dodar]

wow what happened to this thread?!? lol
it just died out, anybody got anything interesting to add to their robots for this special occasion?

[Nick Lawrence]

We had a fever.

We cured it.

We got MOAR COWBELL!!11

The entire division is a sleeper. We'll all stay relatively tame till the last elimination matches on Saturday, then go into Einstein full force and decimate everyone. XD

ARCHI--OHWOW2009WORLDCHAMPIONS!

665 is changing our ball dumping mechanism a little bit... we were probably getting 8/10 balls in during a dump before, we should be hitting 9 and 10 per dump with no jamming like we had at Florida

Let's see scouting wise, I have split scouting between me and another teammate and I have 39-1341. I have notes on all of the robots right now..the teams I'm most impressed with right now are:

61- For lightning fast dumps and reloads
201 - Great drivers, looked like they were mostly playing defense - I'm not sure if there will be any primary defensive bots on the alliances in Archi, but if there is, I would bet these guys would be high up there on that list
280 - While seeding 54th at the Michigan CMP, they were picked 5th and have great ball dumping speed and accuracy from what I've seen
488 - Looks good, accurate ball dumps, don't have a lot of info on them
624 - I think I was most impressed with 624 - these guys will make you pay if they get near your trailer, reminds me of 1114 a lot.
868 - Target acquisition, quick dumps and quick reloading make these guys a force to be reckoned with
1114 - Well built as always, they'll make you pay if they get near your trailer - but they've proven they can be beaten.

Consider this my mini-Looking Forward post for half of Archimedes. There are other good teams, but these are the ones that impressed me the most. I may post my observations for the next half when I get the results back.

So who MCs Archimedes usually?

[Nick Lawrence]

Don't forget 1538, they look solid.

What would you like to know?

Obviously, we're very happy with how our robot's performed so far this season and are looking forward to unleashing it on the world.

-We collect rapidly from the ground; it'll grab a group of six+ balls in two or three seconds, typically.
-Hopper holds 18 balls comfortably, more if we human load on top of what we've collected from the floor. We can also store balls in our conveyor if necessary.
-We can unload our entire hopper's contents in a bit less than 2 seconds and are 95%+ accurate. We don't sweat dropping one ball when we're carrying 16.
-We have 8 unique autonomous programs that run from any starting position. Some hit very hard.
-We have traction control on demand. I'm confident saying we had the fastest robot in both Portland and Seattle.

Our data shows we averaged 12.5 balls scored/match by our robot in Seattle over seven matches. In one match, we scored no balls because we got greedy and ran out of time after collecting 20+. We did not collect data for any of the elimination rounds, but were undefeated throughout at Seattle. Our +/- was about 16.

Let me know if there's anything more you'd like to know.

How do you keep them in your hopper? do you have an unloader kinda like 1625?

[Greg Peshek]

That's great.. thanks Madison. That should make my job a lot easier. I just didn't have a ton of info because unfortunately... no videos of your robot on TBA. Which is how we get a lot of our info.. a lot of watching film and analyzing robot's performance. But I did see your guys' robot on the webcast, so that info combined with what I've seen helps a lot.

Gravity? I'm not intimately familiar with how 1625's machine functions, but our hopper is a cavity and the rear of the robot that is lined with a length of rip-stop nylon fabric. That fabric forms a 'U', with one end fixed to the front of the robot and the other wrapped around a spool driven by two CIMs. We spool the fabric up rapidly and that 'U' becomes a '_' or, really, something closer to a '/'

It's not dissimilar to 20's robot or to any of the machines that lift the balls up from below -- 111 and 1280, for example.

Yeah, there are videos of all our matches available online, but I'm not sure if the folks that parsed them are okay with uploading them to TBA.

If anyone's interested in seeing more, you can find video of the Oregon Regional and the Microsoft Seattle Regional at bpsepaa.com. Login and password are each 'guest'.

Nice Job! Very interesting to see!

[santosh]

The map doesnt have 2415. instead it has our daughterish team 3091 listed twice.
