What FRC Calculators do you want
 

Note: all abbreviation meanings can be found below.

I've developed an FRC calculator that can so far, take (Wheel Size)+(RPM)+(2 stage gearing)=(FPS). And a Linear Actuator Calculator that takes the (RPM)+(2 stag gearing)+(Thread Pitch)+(TPI)+(Actuator's overall travel distance)=(DPS) and (TTC).

So now on to my real question, what kind of calculator would you like to see implemented or have? (examples would be, Center to center gear/belt calculator,etc.) Thank you for time. :)


Abbreviations:
RPM = Revolutions Per Second
FPS = Feet Per Second
DPS= Distance Per Second
TPI = Threads Per Inch
TTC= Time To Complete

A district points calculator

Are you talking about a what if calculator? The FIRST and TBA ones update nearly live. What capability do you feel they lack?

Re: What FRC Calculators do you want
 

Yes a what if calculator. The capability they both lack is input from the user to see what would happen with a certain ranking, award, playoff performance/selection.

Re: What FRC Calculators do you want
 

I would try and develop calculators that aren't already in the JVN Calculator.

As for what I would find useful:
Might be helpful to have a calculator that took the path length of a belt/chain run, the C/C distance of this belt/chain run, and give you the lateral distance off the centerline where a tensioner would need to be placed to properly tension the belt/chain run. (I have no idea if I explained that well.)

Also might be nice to have something that calculates the amount and placement of counterweight and/or counter force on some sort of arm so that it is balanced.

I'd be over the moon for any calculator that uses metric nativley.

In fact, last I checked, JVN's calculator did a lot in metric, with conversions on the inputs and outputs. It's also funny to see imperial calculators for metric pitched belts...

A time-to-distance drivetrain calculator with an experimentally determined friction model of the robot that also factors in voltage drop of the battery.

Re: What FRC Calculators do you want
 

I'd be understating myself if I said that was a tall order.

Re: What FRC Calculators do you want
 

What outputs would you like, or how would you like to us this tool?

Re: What FRC Calculators do you want
 

It's really not that bad actually, and I believe a few versions of that (or darn near it) have been posted over the years.

Re: What FRC Calculators do you want
 

I have seen/heard of a few versions.

I think with the PDB now reporting channel currents, and even more accurate version could be correlated with a little bit of testing. That being said, If the tool is meant to be a predictor, then very little test information would be available at the time.

Re: What FRC Calculators do you want
 

I've seen it, but not with voltage drop factored in before. This would be the Holy Grail of drivetrain calculators, I think.

Re: What FRC Calculators do you want
 

Unfortunately, my current level of electrical knowledge is no where near what i would need to now about battery consumption so I will most likely not add that in until way later:( but I'm still open to other suggestions

(sorry for the bad pun :rolleyes: )

Re: What FRC Calculators do you want
 

There was an Excel-based extension to JVN's calculator that 841 pulled down from CD & used extensively in design this year (though we have not verified the results).

I can't find it right now though :confused:
Probably using the wrong search terms.
