Thanks again for all the replies. I believe I have added a constructor as Mike explained and passed the hardwareMap to RobotDrive and I still receive the same results: it goes to the catch block. If there is a better place for me ask the question than here I am would be be willing to move it but i appreciate your kindness.


Updated code:


*********************************************

package com.qualcomm.ftcrobotcontroller.opmodes;


import com.qualcomm.robotcore.eventloop.opmode.OpMode;

public class Brain extends OpMode {

private int statusDriveInteger = 76;

private RobotDrive rd = new RobotDrive(hardwareMap);



public void init (){

statusDriveInteger = rd.statusRobotDrive();

telemetry.addData("here ",statusDriveInteger);
}

public void loop (){
telemetry.addData("here pre",statusDriveInteger);
rd.setPowerLeftRearDrive(1.0);
telemetry.addData("here post",statusDriveInteger);

}

}
