Labview help: How do you use a gyroscope to level something controlled by two motors?

[Ragingenferno]

Hello,

I'm from team 3053 and I’m asking for help making an auto leveling system for our part on our robot. It is kind of like a scissor lift. We are using two motors to control it.

Can someone assist me in doing this please. I attached our code that we have right now.

So basically, we have two motors, one is controlling the right side, one is controlling the left side. When both motors are moving, the "scissor lift" like mechanism raises. We wanted to attach a gyroscope to the bottom of it to automatically adjust the speed of the motors as we manually raise it with a button.

How can we do this?

What you're describing seems better suited for motor encoders.

[Ragingenferno]

I still wouldn't know how to do that. Could you describe or give me an example?

[xXhunter47Xx]

To be completely honest, we're in that hole too.
What kind of motor controllers are you using for the motors? Jags or Vics or Talons?

[Ragingenferno]

For the small andymark motors for the lift system we are using victors. I know how to do most things for controlling the robot just not the advanced things like using a gyro to stabilize things.

Are you just trying to get both motors to raise the lift evenly?

[Ragingenferno]

Yes, pretty much but controlling both motors from the same PWM isn't working out as we expected because the load on top isn't centered. That's why I thought of using a gyro to fix it.

[xXhunter47Xx]

Interesting. Encoders as far as I know have to be on Jags.
Now what you could try doing is setting each motor with different output speeds and twiddle with that.
IE if one is going faster, slow it down a little and speed the other one up in labview.

That would work but we are not certain how the ball will land on the lift. The lift will hold our ball along with pneumatic pistons. I think you get the idea of what we're doing there.

So gyro's in labview is that hard?

[xXhunter47Xx]

Not necessarily. I would write (I mean draw) an example for you but it's late and I don't really have the time to. Check out team 358's website on labview though, they have great examples that we've been utilizing.

[Ragingenferno]

Okay no problem.Well, I already know how to code for gyros and things of that nature. I just don't know how to utilize the data it sends back as a variable and unfortunately the site(or at-least i couldn't find) doesn't have an example for that.
