Introducing team 3958's 2013 robot: BIG SWEEEEP

[Pault]

Spoiler for big image:

Weight:118
Hi gear: 15fps
Low gear: ~6 fps

Shoots, scores, hangs for 10

Features:
Realistically holds 3 frisbees(we are cheating in the picture)
Linear actuators move arm up and down
Shoots from under the pyramid or the corner
Picks up from the ground
Makes 90-100% of autonomous shots

Motors:
4 cim's on drive train
2 pg71's on linear actuators
2 other andymark motors on indexing
2 bag motors for "daisies"(our pickup mechanism)
2 other andymark motors on our "wrist" actuator
1 cim on the shooter

(total of 13 for those of you counting)

Mechanical accomplishments:
all sprockets are laser cut abs
Linear actuators to move our arm up and down
'Daisies' made out of a combination of laser cut red rubber and ABS
Bumper is the strength of the chassis
32x23.75 wide bot
4wd with kop wheel and Super Shifters


WPI regional: averaged 0.42 points a match (5 points over 12 matches)
We missed almost all of our matches because we were finishing our robot, and we were programing it too…

Boston Regional: averaged 42 points a match (our opr), semifinalists
with 1100 and 2349, 6th seed, audges award at the Boston Regional and our mentor received the Woodie Flowers Finalist Award (Joe Johnson)

Oh ya, and we "forgot" to tell people this at our regionals, but it is made out of mostly wood and plastic.

In Boston, you were the only team we couldn't push when we were on defense. My first reaction was that it looked like it had the potential, but i wasn't sure (especially with so many people working around it on Thursday). After watching the robot for a match or two, I wasn't looking forward to driving against that robot in match that next day.

[Jay O'Donnell]

I personally can't wait to come check out this robot at Beantown Blitz. I watched you guys play at Boston via webcast and I fell in love with your robot.

Do you guys have an in-house laser cutter? I did not know you could cut rubber. Reminds me of a car wash scrubber

[Chris is me]

Our scouts were keeping an eye on you all through WPI. I saw your robot start to come together late Thursday and I was really hoping that you'd have a strong Saturday morning and be around as a late second round steal. Unfortunately, it just wasn't in the cards, and with 3182 still available the risk wasn't worth taking.

You guys were really awesome at Boston, turning it up a notch and shooting up to the second overall pick. Can't wait to play with / against you guys at Beantown.

Funny you should mention car wash...

Certainly a well deserved Judges Award, and a long overdue Woody Flowers Finalist Award for Dr. Joe!

We have access to 2 laser cutters at one our mentor's work, and we are allowed to use them on weekends for large jobs. If its just small things that just need to be done quickly, he can make them before/after work.

This year we used it to create our daisies, parts of wrist, our arm actuators, and drivetrain sprockets.

Also, the car wash scrubber was our original inspiration for the design. And, as you can tell, you aren't the only one to pick up on that.

Oh my god I just watched this.
And I am dying laughing here.
3958- you should have come to CT to win that because that was epic.

What rubber are you talking about? The red flap wheels on the pick up?

I'm assuming that is what he's talking about. The "Red flap wheels" (We like to call them the daisies) are made of two different parts. The black part is laser cut ABS plastic. The red portion is a rubber material that is surprisingly good at gripping disks.

Oh thanks, that's interesting. At first I thought they were modified Scotch Brite wheels lol.

Thanks, Did it allow you to pick up disks that were out of alignment?

Yea, it was one of the most effective floor pickups we have seen. In fact, it aligns disks well enough that it has the potential to do a 7 disk autonomous, although we haven't found the time to program one... Yet
