But why? I can understand lightning fast climbs in previous games, since it afforded you to spend more time on other actions right up until the end of the match. That's far less important in 2017. There's no such thing as "buzzer beaters" in 2017. Fuel takes 1-2 seconds to process at the very least (and can get backed up due to the limited processing rate). Gears are even worse, as the gears aren't actually what's being scored, rotors is. You have to allow time to place the gear on the lift, raise the lift, take the gear off the lift, place the gear on the airship, and spin the crank 3 times. That's going to take a few seconds at the very least. There's really very little advantage to being able to climb in <3 seconds.

I simply don't see the need to throw 800-1000W of power at your climber.

Low goal? I look forwards to seeing vomit bots.

Very fair points, I hadn't really thought about the fact that there are no buzzer beaters this year. My thinking was simply less climb time meant more scoring time. I suppose there isn't a huge advantage to climbing in .5 seconds vs. climbing in 2 seconds.

I think we're going to see many robots using the same motors to power multiple subsystems both through the use of PTO's and through pure creativity. I think that'll lead to a lot of teams being able to climb very quickly, hence why I said we'll see a lot of .5 second climbs. While .5 seconds might have been an exaggeration, I still think we'll see a lot of really fast climbs.

Re: How much Power?
 
so far....

4 CIM drivetrain
1 CIM climb
1 compressor

Re: How much Power?
 
Drivetrain: 4 CIMs
Fuel intake: 1 Bag or MiniCIM
Fuel indexer and injector: 1 MiniCIM or CIM (we are a low goal bot)

Still designing our gear manipulator, could use 1 Bag or may be passive.

Re: How much Power?
 
Drivetrain: 4 CIMs
Gear: 1 Window Motor
Ball Shooter: 1 MiniCIM and possibly a servo
Ball Intake: 2 BAG Motors
Rope Climber: 1 CIM

Re: How much Power?
 
The Bionic Blackhawks are using:

Drivetrain - 6 CIM's
Shooter - 1 775 pro (though I'm pushing for 2)
Intake - 2 BAG
Climber - 1 mini CIM
Gear - 1 bag and 1 snowblower/servo for actuating our grip on the gear

Unfortunately, I'm not sure I can really reveal too much information yet, but we're looking like we might be too tight on space to afford extra motors.

Our team is highly in favor of powerful drivetrains. Last year, we had only 4 CIMS, due to the design of our raised middle wheels to assist with the breach (4 wheels on carpet, 6 on some defenses). However, we also chose a 2 reduction clamping gearbox, and 8" wheels that made us both fast and strong. This year, we planned to do the same, but with 6 4" wheels instead. We calculated the speed to be about 4 ft/s, so that was quickly shot down. We would use the WCD design, but space is limited and the belts are obnoxious. I think what we did was a valid trade off, but I think we struck a balance of power and speed. No, we will not be using anything like Mecanum or Swerve. I don't plan on spoiling what we did with 6 CIMs though.

Our shooter currently has 1 775 pro, which is quite under powered. I'm in favor of adding another directly opposing, and removing our 3:1 reduction. This would give us a 2:1 stalling torque, yet still a 1:1 speed. As it stands, we barely reach the goal at maxed power (4 inch flywheel). My only concern is voltage. Last year, with 2 775's on our shooter, we had to be lined up before revving, else our voltage would drop and we couldn't move left and right. I think not having literally a square of pneumatic wheels would help.

As for the gear mechanism, well, let's just say I hope you guys get to see it sometime. It's really... unique? We hope that our strategy was correct and people don't plan on driving over gears.

Our climber is a winch, about 1.5-2" diameter, that will climb up webbing. It's a quick little thing, so we'll see how we do.

Our intake, in its prototype form, is required to throw the fuel up about 18". I hope this isn't the final design, especially with BAGs being inferior to 775's.

Not 100% convinced that 1/2 second climbs will be worth it this year. Given the delay on ball scoring, using the last seconds of the match to score balls is less likely to come into play than in previous years. A 1 second climb doesn't seem unreasonable to me with a 2 Cim climber, so I suspect 271 has something more interesting up their sleeves.

But maybe that's just because I like them :D

We'll be using-
drive train- 4 cims
shooter- 2 775 pros
collector- 1 775 pro
indexer- 1 bag
winch- 1 bag
various pneumatics

Re: How much Power?
 
6 CIM Drive
2 MiniCIM Climber
1x 775 pro shooter
1x 775 pro intake
1x ??? agitator
1x compressor

Re: How much Power?
 
These aren't yet finalized for the most part. This is for 228.

4 CIM - Drivetrain
1 CIM (option for 2) - Climber
3 775pro - Shooter
1 BAG - Dumper
1 Minicim - Indexer
1 Minicim - Intake
1 BAG - Gear Roller

Some of the BAGs and MiniCIMs might get switched around, or replaced with more 775pros. Lots of VPs involved here.

I think our pneumatic usage will probably warrant an onboard compressor.

Climber - 2 x CIM motors.

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