'Snow Problem 2015 - Stronghold

[Chief Hedgehog]

Love it. That is a pretty incredible robot. I wouldn't expect anything less from you guys!

[Abhishek R]

Wow! It's so compact, I love it. Easily my favorite so far. I love the motion of the intake when it retracts/extends. Very well done.

Thanks! We really like it too.

Like Ryan said, we didn't get a chance to test these items but there would be enough room to modify our manipulator on the back to do all of these. Theoretically it should be able to lift the portcullis and possibly open the sally port. Currently, I can assure you it would not do the drawbridge, but there are some simple designs we could do to solve that.

Excellent work. Loved watching the live stream, and the robot is great.

[Ginger Power]

Awesome job guys! I'm very impressed with your robot. I'd love to see it in person at some point! Hopefully we can demo them at the Duluth and/or Minneapolis regionals.

Clever, subtle adjusting intake. Nice!

It originally didn't actuate and we intended to extend our frame perimeter beneath it, but realized that we would have trouble breaching some defenses with both the extended perimeter and bumpers. Linear actuation seemed to be the easiest method to work around that

And it works to hold the ball on the catapult I imagine

Any thoughts of signing up for the Eagan week 0 event and bringing it down there? #hinthint

How big is your intake? How large is the gap in your bumpers? We're talking about building something similar, but there's some discussion about whether maximizing roller size is worth doing (in which case we'd have to come over the bumper). Thanks

We had pretty much the same discussion, and given the time restrictions went with this design. The gap in the frame is somewhere around 11-12 in.

Yep, it helps to retain the ball when traversing the defenses.

With this exact design, Perses actually cannot fit legal bumpers on the intake side. This is easily remedied by making the robot a few inches wider-- we used the square kitbot configuration, which comes out to about 112" of perimeter, which is enough for you to add a few inches of width and have both a wider intake and a legal robot, both of which are great side effects

Edit: I just thought I'd add on some more relevant information. Jimmy is right-- the gap is about 12".

[rpaulsen]

Will a 3x3 8" pneumatic wheel drive train fit on the square chassis, or will the outer wheels interfere with the outer plate?

Lol.

Cool actuation on the intake, serves many purposes.

Can it do the low goal?

It can, provided that the ball has not been sucked all the way up into the claw. It would be trivial to add a cylinder or servo which pushed the ball back out of the claw and into the intake, but 72 hours is only time for so much.
