# Waffles

Waffles is Steel Ridge Robotics' (FRC 6343) official swerve drive codebase, which began development in late 2022.

## What is swerve drive?

Swerve drive is an omnidirectional drive train where all wheels are independently steered and driven.

This gives us unique advantages over other drive trains:

- Strafing, driving left to right, is possible and more efficient than mechanum drive trains.

- More speed conserved when turning, since the robot has no need to rotate.

- More traction with the ground than a mechanum drive train. (Can't be pushed around as easily)

- Flexing on other teams.

# Software Overview

Waffles contains the following:

- Fused CANcoders for precise steering

- Continuous wrap for optimized steering

- Motion profiling combined with [field-orientated control](https://en.m.wikipedia.org/wiki/Vector_control_(motor)) to reduce skidding and improve handling.

- Ability to switch between robot-centric and field-relative modes.

- Skidding and collision detection, to compensate for errors in autonomous driving.

- Advanced joystick mapping to ensure maximum speed.

- PathPlanner support (includes Choreo configuration)

- NavX simulation

- Full simulation support for all modes

- Auto Trajectories Visualized in Shuffleboard

- Shuffleboard and Elastic Support

# Technical Overview

Our swerve drive is comprised of the following:

- 4 swerve modules in each corner of the base frame

  - 2 motors in each modules (8 motors total)

    - 1 for steering the wheel (the "steer motor")

    - 1 for driving/spinning the wheel (the "drive motor")

We use [Falcon 500](https://store.ctr-electronics.com/falcon-500-powered-by-talon-fx/)s for each motor, 

as well as 1 [CANcoder](https://store.ctr-electronics.com/cancoder/) for each module.
