Aww, come on... It was just a practice match :)

Re: 2011 Curie Division
 

Thanks for the great division review Trent! Look forward to seeing you in St. Louis!

2783's bot: (no pics yet)

Autonomous- hangs one tube (will be consistent once replacement parts come in) on high

Teleop- can hang any tube anywhere

Endgame- linear slide minibot lancher poowed by a window motor, latest minibot is held in with a cable and hitch pin system. the minibot latches onto the pole with 2 70lb (force) wind turbine magnets. current minbot goes up in 4 seconds (a direct drive version may be made)

mechanics:

drivetrain: high speed mecanum (4x cims/ TB nanos). it is normally run at 50% power for preciceness and rant at full poer for speed when the "turbo" trigger is held.

arm: the robot uses a 3 stage arm controlled by 2 geared down BB 550's and 2 springs. all 3 segments work in sync by a cable/pulley system. a 550 or an FP will be on the wrist and the gripper also has a bb motor (forgot the model). the arm, wrist, and gripper all have analog encoders for precise preset positions.

the robot has a low center of gravity (it has never come close to tipping).

the robot has a direct fed (though AP, bypassing the cRIO) camera, controlled by a tilt servo (180 degrees). the current code (perfected tonight) gives drivers real-time video with crosshairs for guiding when the camera is facing forward, and when it faces backwards (to launch minibot), the crosshairs switch to 2 vertical lines (to line up with pole) and the image rotates 180 degrees. the tilt angle is set by the driver's righthand throttle.

the current arm (not used in regionals) is being used on a practice clone chassis, and at 23lb, it will be brought in as withholding allowance material.

Good luck to curie!

Team 1923's robot specs:

Reliable autonomous with scoring on top row (has only failed to get points once at CT)

Can score on all three pegs and averages about 1-1.5 logos per match

Has set the high score at NJ of 124 with teams 25 and 1860

Has set the high score at CT of 123 with teams 195 and 155

Third seed at NJ, first seed at CT, winner at CT

~1.3 second minibot w/o deployment (wasn't there at jersey), not timed w/ deployment, estimated 2 second deploy and climb
The inspiration for this minibot is from Team 40(Trinity Robotics from Manchester NH). Thank you for being gracious competitors and helping us out!

SEE YOU GUYS ON THE FIELD!

Re: 2011 Curie Division
 

Can't wait! Team 3459 is an all rookie team. None of us have never done this before! We placed 7th out of 52 at our regional, and are thrilled about going to St. Louis. We think we have a pretty good robot. We were going to borrow a minibot from a team at the NC regional, but we never got in contact with them. Don't know how we'll do, but we'll see! See you all in St. Louis!

Re: 2011 Curie Division
 

Glad to see you guys in our division. First time for all of us in St. Louis, so we are all noobs in a way.

Re: 2011 Curie Division
 

If you guys have the parts available (motors, limit switches, c channel, bushings) I think plenty of teams would help you put one or two together. 3553 used to have a pretty ghetto looking minibot that still went up in 1.5 seconds that they could probably help you build.

Re: 2011 Curie Division
 

57 is going to have a few extra minibots, and we have an extra, slightly crooked deployment system as well. Find me in our pits around 6 on Weds and we'll talk.

Re: 2011 Curie Division
 

I wouldn't be opposed to helping you build one! pm if interested or find me at champs wearing a team titanium shirt and a hat(I'm literally going to wearing that.).

Re: 2011 Curie Division
 

Ahhh!!! Giant Mexican Hat in potentially uber crowded pit field bleachers. :eek: :ahh: :eek: :ahh:

Re: 2011 Curie Division
 

It looks like they already have a deployment system (that works, I saw them deploy in a QF match video). Unless of course that was a loaner, too (considering it has a different minibot on it in the pic (prob theirs in Qual 14) and vid (prob loaner) I think it is their system). I think they should probably choose which ever minibot fits their deployment the best, so lets give them options.

I offered them one of our loaner minibots as well via PM (to a couple members of their team). I think PM is probably the way to go (for other to offer minibots) since members of their team might not read the rest of this thread. I have a read receipt but no responses yet.

Re: 2011 Curie Division
 

Thanks everyone willing to help! Our team is meeting tonight, I'll bring it up :)

Re: 2011 Curie Division
 

Just in case anyone missed our other thread, we have posted a link to our Curie robot photo database that everyone is welcome to utilize. Keep checking back here as we will continue to add the missing pictures.

http://www.chiefdelphi.com/forums/sh...threadid=94758

We pulled these pics from team websites, other CD posts, and have now resorted to screen captures from YouTube clips. So, if we don't have a photo or it is not a very good picture of your robot, we apologize but you've hidden them well....

Re: 2011 Curie Division
 

Mmmmmmmm... I'm a newly minted fan of the deployment systems that extend a rail with an alignment device, and then fire the minibot down the rail.

I don't know about other non-magnetic, direct-drive minibots, but ours is sensitive to misalignment. If the deployment system pushes the minibot sideways against the pole, then there's too much pressure on one roller, not enough on the other, and the minibot just spins out. Plus all the concerns about bending shafts and such. So while I'm willing to loan out minibots, I'd also like to set up the loanees for success.

Re: 2011 Curie Division
 

Team 3492, RoboGens, is another Rookie team that is excited to be going to St. Louis next week! :)
