If you look a little into 121's history you'll find that they are quite aware of the wedge rule.

They are scheduled to go to the BAE Systems Granite State Regional.

Good luck everyone!

RAZ

for some reason I'm gonna take a wild guess and say your secret weapon is the big metal thing running around in circles with the trackball, but I could be wrong

[Mark Holschuh]

It looks like your secret device might be what ever you used in your claw that allows the trackball to spin in one direction, but not in the opposite direction when you are letting go of the ball.

Either that or its the mentor at the end of the field that catches the ball.

NICE JOB. the effectiveness of this manipulator is amazing! and all because of that one little spring!
does the roller have to be spinning all the time? or does the ball fall out without constant infeed?
also, does your manipulator work even with bumpers on the robot?

That would be me at the end of the field catching the ball. I'm the newest mentor, so I guess I might count as a secret device this year? Or something like that....

Correct me if I'm wrong, but I noticed that your wheel arm is resting on the overpass. Does your arm extend even further down when the motors have no voltage applied?
It made me think of something, to the point that teams that worry about their arms falling with no voltage applied due to weight may not necessarily have to worry too much.
I am thoroughly impressed!
Great job you guys!

Its geared down a lot, which makes it really hard to drop down on its own. In fact you really have to force the arm to manually move.

i was looking at video again, very nice as said earlier, but i thought i saw alittle wobbling after you placed ball on overpass.have you tested the arm for strength. you know, maybe hit it from behind with ball coming down from overpass. better to find out now then at regional.

The wobble i think you're referring to due the fact that the "tusks", or lower part of the arm, is mounted on a pivot and attached to a tension spring.

Nice Job Guys!! I do have a couple of questions though. Do you stay within the 80" cylinder when you hurdle? How do you knock the ball off the overpass?

We have a similar concept, and I hope it works as well as yours. Our prototype works well, but our finished product will not be done till this weekend - we will see then!

Great job abd thanks for sharing.

Doesn't the ball have to roll across the finish line, without touching a robot? According to rule <G10>?

Each TRACKBALL that has CROSSED its own FINISH LINE while not in contact with a ROBOT of the same ALLIANCE will earn 2 points. A TRACKBALL that has CROSSED its own FINISH LINE which contacts ROBOTS of both ALLIANCES while CROSSING will earn 2 points.

Can someone please help clarify this rule for me?

That rule refers to CROSSING. There is a separate rule for HURDLES.
