2019-inseason

FRC Team 973: The Greybots 2019 Code for Destination: Deep Space

2019 Houston World Champions!

2019 Orange County and Sacramento Regional Autonomous Award Winners!

Getting Started

Welcome to the 2019 Robot Code for the World Champ robot: Fireball! We use Gradle to build here. For a walk-through on installing the build system on your computer, check out guides/InstallGuide.md. Then, run ./gradlew build in the top-level directory.

Main features

Some unique and interesting features to look for:

• Custom vision alignment control algorithm used in teleop and sandstorm by running three PID loops off the roboRIO based off Limelight x-offset, y-offset (for real time distance calculations), and target skew/rotation
• Automated L3, buddy-L3, and L2 climb sequences
• Limelight as a source for driver feedback
• State machine to handle automated motions for simultaneous elevator, cargo, and hatch intake
• Current low-pass filtering for cargo intake
• Utilizing motion magic control mode on Talon SRXs for elevator motions
• GreyDash - custom, real-time dashboard primarily used for tuning PID and reading miscellaneous robot data (based on FRCDashboard pre-electron)
• GreyCTRE/GreySparkMax Wrapper - used to set default values for all Talon SRXs/Victor SPXs and Spark MAXs
• Coding style checker at commit following our own style guide (found in the tools folder)
