How much Power?

Why 9015s over BB550s or 775s? I have never really found the 9015s to be attractive because of the presence of those other options. If you are looking for a form factor smaller than the 775, what advantages does the 9015 provide over a BB550? From experimental motor stats, the 9015 comes in with a power rating below the BB550.

From a location standpoint our team can get 9015s same day vs waiting on a 775pro or bb550.

Ding ding ding ding!

I've used a lot of BAG/775pro/etc motors in the past, and they're very good. But as a team 20 minutes from AndyMark HQ and sponsored by them, being able to get parts that afternoon and without shipping costs does give the products on the AndyMark shelf a lot of weight. Where it makes sense to go elsewhere, we go elsewhere.

The students designed a Gear device that doesn't need any active mechanisms. I've seen the testing and like it a lot. If there is going to be an active part of it then it will likely be pneumatic.

Here's my explanation of why 1712 has historically opted for the AM9015 over the BB550. There may be specific applications where the higher power is worth the additional gearing required to get the free speed into a usable range (such as a flywheel shooter tasked with rapid spin-up), but for most high RPM, low-torque applications we opt for the 9015 over the 550. Plus most of those high RPM, high power applications we'd opt for a 775Pro over any 500 series motor.

If you're using 775's to power your intake:

1. Are you using Versa Planetary, if so what reduction?
2. Dual or single input?

Single input versaplanetary 25:1 reduction.

Teams should keep in mind that the roborio only has 10 pwm ports (if that is how they're planning to control their ESCs). And Relays only support 20 amps and lower (775s/CIMs/miniCIMs are greater than 20 amps).

10 PWMs on the roboRIO + 10 PWMs on a legal active MXP board = more than most teams will ever need

Also if you use talon SRXs, that adds another 64 motor controllers through CAN

Even ignoring that various expansion boards exist to let you get to 20, Y-cables allow you to send the same PWM signals to different motors. So your drivetrain should only need 2 PWM ports even with 4 or 6 motors in it. Any intake using multiple motors can follow the same principle - only one unique signal, only one PWM port.

6 cims(drivetrain)
1 mini cim(climber)
2 bags (intake and indexer for shooter)
1 775 pro (flywheel)
3 pneumatic cylinders

[Lil' Lavery]

Current allocation:
6CIMs
1 775 Pro
1 MiniCIM
5 Cylinders

[Fusion_Clint]

5 CIMs (4 Drivetrain and 1 Climber)
3 9015’s (Fuel Intake, Hopper agitator, Shooter Feeder)
2 775pro’s (Shooter)

Still haven't decided on gear mechanism, most likly it will be pneumatic.
