The method getAngle in Arm system will change.

I added 2 methods for 2 different directions - backwards and forward.

Add the word static to each constant field.

In here, read the absolute encoder in order to find out current angle.
How to read and use the encoder

Moreover, you can always use Ctrl + B in order to see how the DutyCycelEncoder works

Once you've fixed everything, commit & push, and pull request again

I haven't seen you creating in SystemFactory the arm system-so create it(and use RobotMap as well)

Specify the variable to angle2Target

What is that?

+        DutyCycleEncoder encoder = new DutyCycleEncoder((DutyCycle) RobotMap.ARM_ENCODER);
+        double angle2Target = RobotMap.ARM_ANGLE;


The angle2Target is set by the encoder value! :) use the encoder.position

Without angle2Target

Set error and limit values- it's an angle, so don't use set too much but not so little as well. Choose from 0.5-1

It shouldn't be here. It should be in the initialize- We don't want everysingle second to reset the encoder

We don't want to use just a specific set point, as you do with angle2Target value. But rather we are looking for the target angle to be provided depending on use, so it should actually be a parameter.

@NoamZW @Maayan-Luzon you may want to discuss this with @stavit456.

I built Arm system and action.

The method getAngle in Arm system will change.

I get the angle from the encoder.

21bd36e

I added 2 methods for 2 different directions - backwards and forward.

getAngle in Arm system is still constant.

I combined the 2 forward and backward methods into one method - move.

Are you sure you want to change the base?
