How To Determine High Strength or High Speed

We have some of our motors set to high speed, and some to high power (internally geared). When we took our robot apart, we forgot to separate the motors by type.

Is there any easy way to determine the motors internal gearing (besides taking the motor cap off). Can I run it with a gear on it to see if there is a difference (will I be able to see the difference?), or can I use ROBOTC to help me?

Thanks :stuck_out_tongue:

(I guess this would be an “AWW shoot” moment right here ;))

If you attach a gear/sprocket with a marker attached at one point around the edge (like a screw or standoff or even a piece of tape) to each motor, then run them simultaneously, you will see a pretty significant difference between the two settings (100rpm vs. 160rpm).

Alright, thank you! I will do that!

I actually had a high speed and high strength chained together at one point… it did not end well for one of the motors…

Which won?

think both lost :stuck_out_tongue:

Yeah I replaced them both one was completely destroyed could not spin it at all ( I think the HS) the other I just replaced just because I thought it was a good idea…

Haha so now my robot has an IME on the right side but no IME on the left cause the screws stripped ( third time I have transfered the IME)

Good thing I’m not using them…

Ohh also on a side note I got like 2 hours of sleep last night :frowning:

I got 9 hours!


I actually got to sleep in and got: 11hr!!!

I feel great! Anyway, thanks for your help.

Well I have regionals…

Please report on what changes you made to your Bot and how you did at your Regional.

He is currently in the finals at New Englands with 2625 and 4886a. Just beat 44’s alliance in semis.

Going to Worlds!

Great job! You should come to nationals too… :slight_smile:

Thanks for the Update!!

Cool!! So, you willing to share your secret? What changes did you implement in the last 2 days??

Hm, sounds like 44 isn’t up to their usual game-breaking domination. I wonder what’s up?

@Androind4Life: That’s a very impressive result! Congratulations!

I think I actually tipped 44 of course unintentionally… I will need to watch the video of it though… 44 built their robot in 6 days before the event quite impressive if you ask me… but they got excellence…

vids and pics plz :slight_smile:

think because all the “elite”/very experienced team members all graduated? (like 1107 this year :()

6 days before competition eh?
cant wait for the usual results when they spend proper time + effort next competition! :wink:

I think you are right about the elite members…

Video will come when 4886a uploads it… I can’t record and drive at the same time…
Also this whole thing was super stressful especially that last game…

I don’t think it’s so much the “elite” members. Their members are all really close friends and it just so happened that they were different years. Three of the original four are in college, so Leland has been on his own the last two years for the most part.
