Pacific Northwest Bots?
 

This is a pic of Madera's 2007 Bot (ETR4) I was hopeing we could get some pictures of other teams attending Portland so we could start gathering Data on teams?

Re: Pacific Northwest Bots?
 

Awesome Design!!! It looks like you guys have it set. Can it only lift one or can it lift two robots?

Re: Pacific Northwest Bots?
 

We should have pictures on our website sometime this week. I'll post here when we do

Re: Pacific Northwest Bots?
 

We can lift 2 bots just our other old bots are all in different states of Refurbishing so the guy standing on the back of our bot weighs about 120 lbs so he is simulating the other bot

Re: Pacific Northwest Bots?
 

team 1501. Can you score i don't see any video of that?

Re: Pacific Northwest Bots?
 

Sorry to say, we cannot score, but we can play some good defense and make it harder for the other alliance to score. Our main strategy is lifting, and we do it well.

Re: Pacific Northwest Bots?
 

k thanks for the info 1 team down 52 to go

Re: Pacific Northwest Bots?
 

What is your website?

Re: Pacific Northwest Bots?
 

team xbot has pictures of our robot in CD-Media for a week or so now.



We're obviously planning on being a defender for most of the match and have achieved a nice balance between pushing power and agility. There's just no use in a powerful drive train if it's too slow to quickly react to a dynamic game.

The lifts are very big and easy to drive onto. We do not require the same degree of accuracy required from any other ramp- or lift-bot I've seen so far. The lifts are deployed independently, though both can be dropped in a matter of seconds. Lifting requires no power at all beyond an initial 250ms pulse that releases the gas springs and the rise to 14" takes no more than 5 seconds. 2 second lift times are possible with a subset of stronger gas springs should that somehow prove necessary or helpful.

Our team's YouTube account has videos of the mechanisms in action -- http://www.youtube.com/profile?user=teamxbot

We'll have some more recent footage and photos soon.

Thanks another 1 down

We lift two robots and score on the Middle and Low Goals. Our Auto is very close to capping as well (either low or middle) ...

Re: Pacific Northwest Bots?
 

Ok so we already have 488,957,1323,1501

Still hopeful for info on
114,192,272,360,492,753,847,948,949,955,956,997,10 13,1087,1258,1280, 1294,1318,1346,1359,1425,1432,1540,1566,1569,1571, 1595,1624,1700,1778,1823,1838,1839,1887,1891,1899, 1983,2002,2046,2071,2122,2130,2142,2147,2148,2149, 2192,2222,2249,2273

I think all this info we are sharing will help know what your alliance partners can and can't do before matches its looking pretty good so far after just a few hours

Re: Pacific Northwest Bots?
 

I have pictures of 492, 948, 1294, 1318, 1778 and 2046 from a pre-ship scrimmage, but I don't know that it's proper to post them without a team's permission.

492 is a ringer scoring machine with a single, 12" ramp; sideways entry. 6WD.

948 is a ringer scoring machine using a vertical lift design; ball-lock 2-speed transmissions. 6WD.

1294 is also a ringer scoring machine with a multi-segmented, turreted arm. 6WD.

1778 has an arm alongside two side-deploying ramps.

2046 is a ringer scoring machine with vertical lift.

Re: Pacific Northwest Bots?
 

Ok do you know their height scoring capabilities? and how many bots can some of them get up?

Re: Pacific Northwest Bots?
 

2273 is a fairly agile arm bot w/ mechanums
i'll post pictures before friday

Re: Pacific Northwest Bots?
 

Here are the teams I have info on

753 -Track Design (Big surprise) Haven't seen anything besides that
847- Arm Ladder Type Design can score on all three
955- Didn't get to see, apparently overweight they were still working on Saturday(Scrimmage was at 955s cafeteria)
956 Can't Climb on others (2 2 inch traction wheels, and 2 casters), can score on all three heights
997 No Arm, Track Design (from 753) Two fold out pneumatic lifters
1087- I want to say it was 4 WD, had an arm, don't remember how effective
1359- Ramp for two bots, 6 WD, Arm for all three goals (more effective for lower 2)
1510- 6 WD Bot, that can climb (on us at least), Good Arm, Can score on any goal I think (effective on low and middle)
1425 -Picture of their two bots are in the gallery somewhere

Re: Pacific Northwest Bots?
 

Hey guys,
Im from team 948. We have the ability to consistantly score ringers, and can place them at all three levels. Last night we added a dropdown ramp on one side, a cover across the top, and a dropdown platform on the other side. (long night) Hopefully we will be able to support two robots at above twelve inches, and Im pretty confident we can do one. We were working on autonomous up until the fedex truck came.

See you in Portland!
(I can't wait)

Re: Pacific Northwest Bots?
 

ok sweet now i need to document all this info starting to look good thanks for your help guys

Re: Pacific Northwest Bots?
 

114 probably won't share pictures or videos until we open our crate at Portland, but here's a couple specs on our monster:

-10 foot forklift scoring mechanism, with dual camera controls to automate scoring in both autonomous and teleoperated
-Automated de-spoiling system, ready for on the fly use
-Simple rack scoring setup, with buttons for different postions
-2 speed drive train (5fps and 15, or push and sprint)
-low CG (approx. 8 inches off the ground)

And, as always, the labcoats will be out in full force.

Lookin forward to the competition!

Re: Pacific Northwest Bots?
 

114 Where can you score and do you have a ramp Ramp? just trying to get some info on all the teams no big deal though

Re: Pacific Northwest Bots?
 

We score all rows at a disturbing pace, and decided to use the weight for a beastly scoring system rather than a rampbot. We've taken our philosophy of picking one part of the game and prefecting it to the max this year.

Re: Pacific Northwest Bots?
 

Well, it's in the crate now... and sitting at customs, but never mind that...

We'll be posting a few photos to the media section later, but here's a quick glance at what we hope will be a good scoring machine. It was inspired by the teams last year that were able to drive up on the ramp and "slam dunk" the balls without ever really aiming. With the low front on our bot we should be able to just drive forward, smash into the base of the rack and self-align. With the ringer held parallel to the floor, it should be an easy fit.

At least that is the theory. We are equipped with a CMU cam and three ultrasonic sensors for finding the light first, then the base of the rack. These can be switched on in telop as well as auto, so scoring on the back side of the rack will hopefully be easier... although just smashing into the base with the bumper aligns us pretty well, too. We still need to test the sensors on the open floor, but it works in small tests on our mock up in the shop.

The lift can reach all the way to the top, but we will probably focus on the middle and bottom rows.

We have no ramp, but can climb at a 20 degree incline, perhaps steeper, and have a belly pan to protect us from forklift designs. It runs on mecanum wheels, and we seem to have them tweaked for fairly decent performance.

Some clips from the build period are http://www.youtube.com/watch?v=gyn9e0cT3-A the sound and editing leaves a bit to be desired, but you can see the robot come together from the first test drive chassis, to testing the PID feedback loops on the drive wheels, to doing some test climbs right through final arm operation. As usual, wooden components play a significant role... "wood is good".

See you in a week.

Heres a preview of what 753 has to offer

Here's the promised photo link to "The Canadian" team's robot... note, however, that we are no longer "THE Canadians" as we are happy to be joined by our friends from team 2273.

Re: Pacific Northwest Bots?
 

Team 949

Has an operational ramp (for 1 bot, 12 inches) the ramp is at a 30 degree angle and was designed for bots to drive on top of our robot.

We also have an arm that is planned to cap on all arm heights. The arm has 2 joints, a shoulder and an elbow.

Drive train is similar to last years (6 wheel drive).

Re: Pacific Northwest Bots?
 

After our scrimmage, Team 956 quickly identified the importance of climbing on others and corrected the problem.

Scoring machine, verticle lift, pneumatics with pre-programmed stops and programmed pick & place sequencers; Dead reckoning autonomous mode (cross your fingers), CAN climb steep ramps.

See you there.

Re: Pacific Northwest Bots?
 

thats awesome... I'm glad that you guys decided to change that.. I can't wait to see it on Thursday.

Re: Pacific Northwest Bots?
 

After much effort, we move! (JK?)
997 looks really good this year, theres alot of potential here this year.
