Spectrum Robot Design Sheet

Spectrum Robot Design Sheet

We are introducing our Spectrum Robot Design Sheet (SRDS). This was inspired by several design calculators and references that have been posted by other members of the FRC Community. A huge thank you to the people that have produced these documents in the past. 

Inspiration for This Sheet and other designs sheets
2232 Master Reference Sheet (Basis for this sheet)
JVN Design Calculator
FRC Mechanical Design Calculator (By Dillon Carey and Aren Hill)
AMB Design Spreadsheet (pneumatics, Chain, mechanisms)

The Spectrum Robot Design Sheet is designed to be a centralized resource to use while designing FRC robots. Each page includes part specifications and calculations that you can use to help in the design process. Many of the COTS parts common to FRC robots have their size and other design parameters included here so you don't have to open up the part in CAD to measure or find and download the drawings every time you need to quickly add something to a sketch or prototype.We keep a copy of this sheet for each robot that we build and then add new pages for each module/subsystem on our robot. That way we can keep track of our design decisions, variables, part numbers, etc in one centralized place. 

You can add new pages for part references or inventory for your team. Timelines or simple gantt charts could be made to help keep everyone on schedule. Please make a copy of this sheet and add your own team's conventions, materials, resources, and references and share it with your team if you think it is useful. If you make a cool page and want to suggest we add it to our public template just send us an email team@spectrum3847.org and we'll look at it.



  • Belt, Chain, and Gear C-C calculators. 
  • Simple drive train, and mechanism calculators.
  • Pneumatic cylinder base lengths, clevis, lengths and more.
  • Gas spring retracted and extended lengths.
  • Sample Module page to document your robot design variables, and decisions.
  • Drill sizes, & bolt sizes
  • Electronics status light reference

"Designing a product is keeping five thousand things in your brain and fitting them all together in new and different ways to get what you want. And every day you discover something new that is a new problem or a new opportunity to fit these things together a little differently.

And it’s that process that is the magic." - Steve Jobs
