Scaling the Tower

Planning on doing both is not rare at all.

Actually doing both will be rare.

That's an interesting question. I think it's the lowest item on the priority list that we've been actively working on, but that doesn't mean we don't plan to have it complete by bag day. Rather that other items, like drive train, electronics, and boulder manipulations are considered more critical/important to accomplish. Hanging is great, but it's just the last 20 seconds of the match. If all you can do is hang, then your use the rest of the match may be questionable. Instead, if you can take care of defenses or boulders, you can be useful the entire match, even if you can't hang. So, by necessity hanging becomes lower priority.

There are other items that are even lower than hanging on our priority list. For example, while we plan to be able to do several of the defensive groups ourselves, we probably won't be able to do all of them. Space, weight, and time constraints all are considerations. But, they are still on the list, just low enough down that they aren't being actively worked on, and likely won't be.

Scaling is pretty low on our list...it doesn't contribute much to getting ranking points. But then, manipulating the moving defenses is also pretty low on our list. And shooting high goals is behind a few other things...like being able to get through most of the defenses (with assistance from our alliance partners), and collecting boulders, and getting rid of boulders

Scaling is the first thing we dropped from the "want to do everything" list. We're building to defeat all but the draw bridge and sally port solo, and secondarily to have a good pickup and score high goals in auto or teleop.

For us it was the very first prototype unit made... hanging is important to this game to be in final alliance

not exactly, our team is planning to use extending hooks attached to our launcher so its about as important to us as launching

Yeah, it's kind of the same for our team. In past years, we've had to develop a relatively simple drive base and a manipulator on top - easy

This year, we have to develop a complex drive base and a laucher, and a climbing mechanism, and a sally port / portcullis articulator, ect. This year has been much harder to strategize and many more things to design and build (let alone practice)

What is the estimated amount of power needed to lift the robot up the tower using a winch type mechanism.

This Much Power

I'd recommend checking out the linear mechanism tab of the 2016 JVN Calculator.

In BreakAway, my team climbed using a single CIM motor, through a Dewalt transmission and an additional small reduction with chain to the winch. Not terribly fast.

In Ultimate Ascent, we climbed using two mini-CIMs through a toughbox mini transmission, direct drive on the winch. Fairly fast for the lifting portion.

So, the amount needed I would say is one CIM. But more power means a faster climb, and fast climbs are probably going to be useful.

Thanks

Does anyone else have any input? I like the idea of the two mini sims but I am open to any other ideas.

how bout 4 CIMS?
They are already on your robot

That may be too much!

In Ultimate Ascent our 2nd level climber used a winch powered by a cimulator gearbox with 2 RS-550 motors. It wasn't fast, but it was fast enough. That robot was within a pound of maximum.
