How much Power?

[Ginger Power]

How much power* are you putting into the primary subsystems of your robot? In other words, what motors and how many motors are powering each system on your robot?

4607 has the following:
Drivetrain: 4 cims, 2 775pros
Intake: 1 775pro
Climber: 3 775pros
Shooter: 3 775pros
Gearage (Gear Mechanism): 0 motors

*What our programmers listen to (and by extension what the rest of our team is forced to listen to)

[Oblarg]

Right now it looks like:

Drive: 6 CIMs
Intake/Shooter/Indexer: All BAG motors
Climber: Mini-CIM

Are you sure about using 775s on the drive? Those do not handle near-stall conditions well.

[Peyton Yeung]

At this point 461 is looking at using

Drivetrain: 4-CIMs

Intake: 1-775pro

Conveyor/Hopper/Feeders: 3-9015s

Shooters: 2-775pros

Climber: 1 Minicim

The 775pros are only powering our strafe wheels which are designed to slip before stalling. It'll be interesting to see how they hold up.

Drive: 6x CIMs + 2 Minis
Shooter: 2x 775 Pros
Climber: 4x CIMs + 2x 775 Pros
Intake: 1x 775 Pro/Bag
Indexer: 1x 775 Pro/Bag

Tehehehe yes those numbers are correct and legal

Kudos to anyone that can figure out how crazy we are

But, why? I'm having a very hard time imagining the utility of having that many motors on your climber. The drive is kind of overkill, too, but I can at least imagine situations in which it would make sense.

I mean, PTOs are great and all, but are they really necessary here (especially with *additional* 775s)?

Half second climbs are going to be a very real thing...

[Richard.Varone]

Like I said if anyone can figure out the full picture I'd be very surprised, we have to one up our 44 wheels from last year after all. PTO is a start but not quite there

[EricLeifermann]

6 cims
6 775 pros
4 or 5 pneumatic cylinders

I, personally, would be rather uncomfortable with the notion of a 150lb robot climbing that fast. That's not something I'd necessarily want our students to be around, either.

Then again, my team is not exactly shooting for Einstein, so perhaps one's sensibilities change at the higher levels of competition.

Agreed... there's a reason I started this thread.

4 CIMs drive
1 CIM climb (with option for second)
Gear hanger (v1) is passive (get going quick for drive practice)
Active gear intake and hanging still in flux, but likely 2 or 4 BAGs and a half dozen or so servos.
Fuel: none planned at this time. Probably no more than a bag and a couple of servos at most.

That's why our can grabbers were going ~30% the speed of sound when they hit the cans. I can use a lot of words to describe that mechanism but safe was so far down that list it may as well have been a mid-Atlantic boat anchor.

I expect to see some fast robots and some fast climbs, but I doubt many fast climbs will be sub 1.5 second.

Are they ignoring Gears? Or is that intake for Gears/Balls/OnlyGears?
