Error building with RR files

[graceliu]

Hi,
I imported RoadRunner files and I am getting build errors. I was hoping virtual robot is able to support RoadRunner. Let me know ideas on how to resolve the following issues?

For example, I would like to use the SampleMecanumDrive, and I get the following errors:

/Users/graceliu/Documents/robotics/virtual_robot/TeamCode/src/org/firstinspires/ftc/teamcode/drive/SampleMecanumDrive.java:27:39
java: cannot find symbol
symbol: class VoltageSensor

java: cannot find symbol

For example, I would like to use trajectory sequence, and I am getting the following errors:

Are you trying to use the road-runner-quick-start code?

If so, the issue is that the quickstart code makes use of both the roadrunner core, and additional code from acmerobotics (and some from FTC, google, etc) that is separate from the roadrunner core, and is not supported in virtual_robot.

The solution will be: 1) add some code to virtual_robot to minimize the incompatibility; then, 2) User removes a few non-critical things from road-runner-quickstart to allow virtual_robot to build.

Work on item (1) is ongoing. Will include instructions for item (2) when this issue is closed.

EDITED 3/7/2023 (again)

Changes have been made to better accommodate the use of road-runner-quickstart. However, several changes to the quickstart files will still be necessary:

From the util package, delete: Logfiles.java, LoggingUtil.java, LynxModuleUtil.java, and AssetsTrajectoryManager.java.

From the drive.opmode package, delete: AutomaticFeedForwardTuner.java

In trajectorysequence.TrajectorySequenceRunner.java, comment out line 26:
//import org.firstinspires.ftc.teamcode.util.LogFiles;

In trajectorysequence.TrajectorySequenceRunner.java, comment out lines 212-217:
// if (targetPose != null) {
// LogFiles.record(
// targetPose, poseEstimate, voltage,
// lastDriveEncPositions, lastDriveEncVels, lastTrackingEncPositions, lastTrackingEncVels
// );
// }

In SampleMecanumDrive.java, comment out line 34:
//import org.firstinspires.ftc.teamcode.util.LynxModuleUtil;

In SampleMecanumDrive.java, comment out line 87:
// LynxModuleUtil.ensureMinimumFirmwareVersion(hardwareMap);

In SampleMecanumDrive.java, change the names of motors in lines 101-104 as follows:
leftFront = hardwareMap.get(DcMotorEx.class, "front_left_motor");
leftRear = hardwareMap.get(DcMotorEx.class, "back_left_motor");
rightRear = hardwareMap.get(DcMotorEx.class, "back_right_motor");
rightFront = hardwareMap.get(DcMotorEx.class, "front_right_motor");

In SampleTankDrive.java, comment out line 34:
//import org.firstinspires.ftc.teamcode.util.LynxModuleUtil;

In SampleTankDrive.java, comment out line 81:
// LynxModuleUtil.ensureMinimumFirmwareVersion(hardwareMap);

In SampleMecanumDrive.java, at the "TODO" comment, line 119, reverse the directions of the left motors:
// TODO: reverse any motors using DcMotor.setDirection()
leftFront.setDirection(DcMotorSimple.Direction.REVERSE);
leftRear.setDirection(DcMotorSimple.Direction.REVERSE);

It is necessary to provide some information about the robot in DriveConstants.java.
The following work well with the Mecanum robot configuraiton in virtual_robot:

TICKS_PER_REV = 1120
MAX_RPM = 160
RUN_USING_ENCODER = true
TRACK_WIDTH = 17.91
MAX_VEL = 28
MAX_ACCEL = 28

Also, max linear and turn velocities can be set as follows:
public static double MAX_VEL = 28;
public static double MAX_ACCEL = 28;
public static double MAX_ANG_VEL = Math.toRadians(175);
public static double MAX_ANG_ACCEL = Math.toRadians(175);

Wow!  You are so fast!  Thank you so much!  I will not be able to try this out today, but will do so as soon as I can.
