FRC CAD Subteam
My journey so far from first introduction of SolidWorks to making full subsystems to making full robots.
Summary
ReefScape
First Dive(2024-25)
Competitions: Orange County Regional(3-9-0), Central Valley Regional(5-6-0), World Championships(6-4-0), SoCal ShowDown(Oct 11-12)
Final assembly snapshot
Lastest cad of our robot before world championships.
Pre-Season
- • First learning Solidworks.
- • Don't understand the assembly first ideology.
- • Never worked on robots like this.
- • Don't know how to do anything.
Kickoff intake (scrapped)
Looked plausible in CAD, failed in prototyping: poor tolerance to off-axis corals and rebound.
- • Too big.
- • Structurally unsound, multiple weak connectors.
- • Doesn't integrate with the rest of the bot.
Climb subsystem (shipped)
Endgame cage climb: this subsystem's job is to latch onto a hanging cage at the end of the game, and lift the robot off the ground. This is the sybsystem I found myself working on the most by the end of the season
- • Clear load paths transferring force directly into drivebase.
- • Existing proven geometry for latch.
- • 125:1 gearbox plus winch provides necessary force to climb.
- • Includes heavy modifications and iterations because the rest of the robot isn't designed with this subsystem in mind.
Practice studies (reverse engineering)
Cadding practice of other team's robots purely from robot reveal and match recordings.
Practice #1 — 1690 × 4414 hybrid
Elements taken from 1690: 4 bar ground intake, ultra-light differential elevator and arm. Elements taken from 4414: motor driven grabber.
Practice #2 — 2910 × 1323 blend
Elements taken from 2910: multi-tool hand for algae and coral, capable of ground intake. Elements taken from 1323: elevator, and elevator pivot.
Competition robot
The design we brought to the World Championship.
- • Demonstrated climb... at least in our last match.
- • Capable of reliably scoring in L2 and L3.
- • Capable of defense.
