I think before this is merged, a lot of testing should be done, but the way you implemented it is nice. Cooking fr

Maybe you want to set the elevator motor speed to 0 when the command ends? Ask mr ishan

too ez- maxc

I hate all of you guys

+                .MAX_PITCH_ANGLE) // TODO if robot is not in climbing state, then do this (AND


We don't care about the state of the elevator when we are climbing right? In fact the elevator should be all the way down while climbing, so this should only help us.

W THINKING MAX L WAS WRONG LOLLLLL

I haven't looked into both of these things enough to comment on whether you guys did this correctly or not....

test it ig -maxxxxxxxxxc

Make this a command factory in elevator subsystem

+  // public static final double MAX_ACCEL_X = 69;


These should be in swerve constants and wouldn't rlly have anything to do with moving the elevator; they just limit the motion of the robot so we don't tip.

    return gyroInputs.yawDegrees;
  }

+  public double getPitch() {


Docstrings?

Make the docstring have a return in it, and specify what units/direction this is in. E.g. Gets the pitch of the robot in degrees, positive being when the robot leans forwards (this is just a guess, I could be wrong, so double check it)

do you need to set both the leader and follower? Couldn't you just do the leader?

+      leaderMotor.setPosition(ElevatorConstants.MAX_HEIGHT);//set encoder to max height
+      followerMotor.setPosition(ElevatorConstants.MAX_HEIGHT); // set encoder to max height


Idk if you want to set the position here, it could lead to the elevator getting zeroed wrong I think

dat da whole point of dis tho

no but like we should only ever zero it at the bottom i feel. Like what if the elevator gets stuck on something while its going up, or it gets 90% of the way up and bc of fucky belt stuff can't go any further?

We should maybe try to "tune" these values, but these are probably pretty good

Introduces a ZeroElevator command to reset elevator position and stop motors.
Implements elevator homing logic based on stator current and velocity conditions in PhysicalElevator.
Updates elevator constants, adds current measurement support, and includes additional safety checks in teleopPeriodic.

MIN_STATOR_THRESHOLD is set to the same value as MAX_STATOR_THRESHOLD, which might lead to unintended logic in the homing method; please confirm that this is the desired behavior.

public static final double MIN_STATOR_THRESHOLD = 59343494;

+  public static final double MAX_STATOR_THRESHOLD = 59343494;
+  public static final double MIN_STATOR_THRESHOLD = 59343494;



The MAX_STATOR_THRESHOLD value appears unusually high; please double-check whether this constant accurately reflects operational limits.

Suggested change

public static final double MAX_STATOR_THRESHOLD = 59343494;

public static final double MIN_STATOR_THRESHOLD = 59343494;

public static final double MAX_STATOR_THRESHOLD = 40.0;

public static final double MIN_STATOR_THRESHOLD = 0.0;

it said 59334343494 is not operational limits???
