This project provides starting Java code for the 2025 REV ION FRC Starter Bot.

Before you can deploy this project to your robot, you'll need to set your team number in /.wpilib/wpilib_preferences.json or via the "Set Team Number" tool in WPILib VSCode. You will need to update WPILib VSCode to a 2025+ release to build this project.
All controls for the Starter Bot are located in /src/main/java/frc/robot/RobotContainer.java and can be configured with WPILib's Command Controller API. The project is configured for an Xbox controller by default, so other controllers may require some additional setup or changes.
The robot's starting/zero configuration is:
- elevator at the bottom
- arm on hard stops
- ball intake out
| Button | Function |
|---|---|
| Left stick | Drive/strafe drivetrain |
| Right stick | Rotate drivetrain |
| Start button | Zero swerve heading |
| Left stick button | Set swerve wheels to an X |
| Left bumper | Run coral intake |
| Right bumper | Reverse coral intake |
| B button | Send elevator/arm to feeder station position |
| A button | Send elevator/arm to Level 1/2 position |
| X button | Send elevator/arm to Level 3 position |
| Y button | Send elevator/arm to Highest position |
| Right trigger | Run algae intake |
| Left trigger | Reverse algae intake |
- Pressing the
Userbutton on the RoboRIO will zero the encoders for coral elevator and arm and algae arm
All configuration objects are instantiated in /src/main/java/frc/robot/Configs.java and called by each subsystem
The Elevator and Arm for scoring Coral both implement MAXMotion Position Mode
The Coral and Algae Subsystems include full simulation examples, complete with Mechanism2d visualizations. Check out the REVLib simulation docs for more information on setting up and running a simulation. Select NetworkTables > SmartDashboard to open the Mechanism2d windows in the Simulation GUI. These displays will also update with a robot connected, so play around with them and add them to your dashboard! They can be configured in /src/main/java/frc/robot/Constants.java.
