AMB Design Spreadsheet
by: AriMB

A set of spreadsheet calculators useful for designing FRC robots.

There is now a v2 with bug fixes and more options here

This is a set of spreadsheet calculators I have designed/compiled for my team to use designing our robot. I am posting this here both to share it with the community and to have it hosted online for my team to use. Feel free to use it or suggest improvements.

AMB Design Spreadsheet v1.1.xlsx (101 KB)
AMB Design Spreadsheet v1.2.xlsx (126 KB)

While presenting the spreadsheet to my students, I noticed a few math errors with converting to metric. They should all be fixed now, so v1.1 has been uploaded.

With kickoff approaching, I figure it’s a good time to post the most recent version on my spreadsheet and bump this thread for anyone who might not have seen it over the offseason.

Changes include:

  • Updated pneumatics calculations based on this thread from over the summer.
  • Added clearance calculator to ensure gearbox gears/shafts don’t interfere with eachother
  • Added calculator to help find closest COTS gear to ideal from Ratio & Distance Calculator
  • Added 2 new legal motors (note: new brushless motors are non-linear so approximations are less accurate)
  • Added ratio tester in Mechanism Ratio sheet to help find reductions that will produce the desired ratio
