Slowing Down Motor On Java

I am a new person to the world of java and i have stumbled on to a problem. When trying to program a prototype arm it goes to fast.::safety::

How can i reduce the speed without changing the arm itself?

Just divide the number you are sending to the set() function by some number greater than 1.

Re: Slowing Down Motor On Java

the code looks for a magnitude value from the controller that ranges from -1 to 1. like jhersh said, divide by some number.

2 would give half speed, for the best results if 2 is too large move the number by increments of .5

Are you using a Jaguar? A Victor? or a Spike?

Re: Slowing Down Motor On Java

So based on what you said I am assuming you are doing something along this line

Code:

Victor a_motor = new Victor(1);

a_motor.set(1);

If you wanted to go slower you would want a percentage of the power so for example 25% power

Code:

Victor a_motor = new Victor(1);

a_motor.set(0.25);

okay yayyyy it worked so awesome.............
but now i have a situation which is causing me a headache.:confused:

how can i control the motor, using the victor, going forward and reverse using different buttons on the joystick cause i need the arm to go up and down.

Thanks so much for your help people i really appreciate it. :D

Set the value to a negative number for reverse direction

e.g. set (0.5) for 50% forward and set(-0.5) for 50% reverse

Re: Slowing Down Motor On Java

Thats easy
Replace # with the button numbers and motor with your victor

Code:

if (joystick.getRawButton(#) == true)

{

motor.set(0.25)

}

else

{

motor.set(0.0)

}

if (joystick.getRawButton(#) == true)

{

motor.set(-0.25)

}

else

{

motor.set(0.0)

}
