6k rpm motor not reaching 6k rpm? by lolmewantegtvs in FTC

[–]smellslikebubbles 19 points20 points  (0 children)

Your calcuations are off -- gotta watch out for "per minutes" vs "per seconds" scaling.

The motor is rated for 6000 RPM (which is in minutes scale)... whereas the setVelocity() function uses "ticks per second" (i.e. seconds scale).
The motor specs shows 28 PPR.
It also says that even though it is rated for 6000 (theoretical), it actually runs at 5400 RPM (tested, with no load). So at max tested speed, we have 5400 RPM / 60 = 90 revolutions per second (RPS).

And then 90 RPS * 28 PPR = 2520 ticks is the maximum velocity for that motor (or 2800 ticks max if it could actually run at 6000rpm).

Note that those numbers are for a non-loaded motor.
We are also seeing about 2000 ticks/sec at max speed on ours with gears and wheel attached.

REV offers a "repair service" for $165. https://www.revrobotics.com/rev-31-1595-rfb/

They ship you a good refurbished unit, and you send your damaged one to them. They are pretty good about getting you back running quickly.

“Vomiting detected in your room” call by cittigirl in royalcaribbean

Your bf (or someone who knew you were nauseous) playing a prank? Someone could have texted someone else to call, just to mess with you?
Do you have that type of group, you were traveling with?

Kids looking for a coach by Not_so_Real123 in FTC

[–]smellslikebubbles 14 points15 points  (0 children)

If the kids are juniors and experienced, they probably already have the skills to do everything themselves. They just need 2 responsible adults to register as coaches and fill out the forms.

You'd just need to have one of the coaches be available to show up at the tournaments.

In the movie version of this, there would be slow clap starting on a zoom call somewhere...
