2020 Spectrum Resource Collection

FRC CAD Collection – Blog – Link – Submission Form – CD

We created a simple system for collecting public CAD models of FRC robots and mechanisms.

The FRC CAD Collection currently has over 450 links to robots from almost 200 teams.
Looking through the CAD of completed robots is one of the best ways to get better at designing FRC robots. You can be inspired by past mechanisms and build methods of teams around the world many you may never be able to see in person.

Protopipe Additions – Protopipe.Spectrum3847.org – CAD Files

We have added multiple new parts and a new mechanism example to the Protopipe system. We have included printable clamps, motor mounts, new connectors, drill adapters, and some small versions of previous connectors. We have also included an adapter block that allows you to combine HYPEblocks, a prototyping system made by FRC#5254 HYPE with protopipe elements.

Updated Guide to the FRC MCC

We updated our guide to the FRC MCC with new resources and tips. We added example MCCs from the 2019 season. We have added a section on sensors and counterbalancing mechanisms. We also updated most of the links and added new vendors to the recommended purchases.

Updated Spectrum Design Sheet

We have added Falcon 500s and both NEOs and NEO 550s to the mechanical section. We have reorganized several of the pages based on how we used it during the 2019 season. We have improved the BOM section and added a parts organization sheet.

This sheet is how we organize our robot construction and helps us design mechanisms without having to re-lookup information over and over throughout the process.

FRC Maintenance Guide

This is the first year teams can do extensive maintenance and cleaning of their robots between events. Ideally, your robot should be squeaky clean and running at peak performance at the start of each event. We started working on a Maintenance guide to use internally but decided to make it public so that other teams could benefit as well.

X-Ray 2019 Robot and Code

Below are our CAD and Code for our 2019 Robot X-Ray

Notes/Research

These are two very rough documents. These are just research docs for two different things we were interested in during the off-season.

Large aluminum pneumatic storage tanks

For robots that use a large amount of air, these ~2 gallon air tanks can be more weight-efficient than the plastic tanks teams often use.

6″ Pneumatic Tires

We wanted to find a 6″ pneumatic tire that could be used in a dead axle drive setup. There a lot of great options, some of our notes are in this document.
