Here is a video of our robot climbing the rope last Saturday.

i mean, im not a cop and cant tell you waht to do but usually people try to make drilling the drivers harder than the game, not easier

shoot for 15 second cycles on a properly sized field
anyone want to report back on this?

We did not have enough space to make it far enough away at the time.

I will post a video soon of our robot doing full speed cycles!

Looking good CIA! See you at Pittsburgh.

In the linked video, it was 9 seconds from motor activation to the touchpad activation. As you guys tune your climber and go into your matches, make sure you account for this! It is precious time taken off of your gear cycles. As a gear specialist ourselves, the whole act of climbing is something we found to be very important. You may be able to improve the time with just a knot at the right height.

It looks really good!

Thanks!

And we have accounted for 10 seconds to hang at the end of the match. That was our first climb test, so we wanted to be gingerly with it. :rolleyes: We will have the knot higher and just drive right into it in a match

I agree completely with Jesse you may be better off with a monkey fist knot as soon as you spin onto the knot it should hook.

We were using a monkey fist knot in the video, but have since changed it to a different, flatter knot that works just as well with our climber. I call it the triangle knot. It is flatter, because we had a problem with the rope wrapping around the ~1" monkey knot and stalling the winch because the effective diameter became too big. The new knot fixed this perfectly though. :D

What kind of rope have you settled on? Have you checked to make sure you can activate the touchpad before hitting the davit channel? From where I can see it could go either way.

As of now we are using a thinner solid braid rope. The vertical struts are meant to activate the touchpad, but we still have a lot of testing to do, and it's hard to be sure without an actual touchpad to try it on. If we do find that to be a problem, we are still a few inches under the 24" limit in the back, so we could add longer struts if we need to.

Apologies then I am colorblind I may have missed the knot. See you in week 3!

Our practice robot is also coming along nicely! We plan on having the gear scorer on it, but not the winch as there is plenty of time for climb testing before bag day.

Hello, I am with team 2544, your lovely neighbor from Harborcreek. I am wondering about the gear shoot. Is it a pilot pull up or a drop off? :confused:

Hi 2544! We have the ability to do both, but we prefer to drop it onto the peg.

Good luck! And see you at Pittsburgh!

What is the gearing on your climber?

Our team was having a difficult time determining how to attach our bumpers and I really liked your usage of wingnuts. How quickly would you estimate you are able to remove and replace your bumpers currently?

This is our first year doing one piece bumpers, but so far they are great! We do not have all of the brackets attached for the bumpers yet, but right now one person can put the bumper on very quickly ( I haven't timed it, but I would guess under a minute). We have a bolt sticking up that is permanently mounted to the frame, and the holes on the brackets on the bumper line up with them, so a wrench is not required to tighten the wing nut. I can post a picture after practice tonight.

We are using a monkey fist also, but at the top of the rope instead.
Looks great and see you folks in Pittsburgh.
