Gyro program..

[Luiz12]

Hi after testing out our robot on a bridge I was wondering if there was a way to just simply press a button while were on the bridge to make the motors run foward and back until the gyro readings are zero. I currently have barely any experience in programing with labview so any examples or any help will do.

Our mechanical and drive team wanted the exact same thing, however once we practiced at a local scrimmage, we found it's actually incredibly easy to balance with just a bit of practice.

As for actually coding something which does it automatically, I'd assume you'd use PID with the Gyro as well as the Accelerometer.

would that be something that would be incredible hard to program, I mean I don't even know what PID is.

[DominickC]

I've never gotten down into the nitty-gritty of PID, so I can't say either way with certainty, but it's in-built into LabView. Experiment with it, but I think you'll find it easier to balance manually, especially because a program like this can't take into account the weight/motion/position/acceleration of a second or even third bot on the bridge.

Because what we ended up finding out is that the robot is top heavy to one side so when we tried to balance it it would just roll off. I mean I truly am a rookie programmer so unless you gave me an example on how to do this I really don't know what to do...

When your angle gets smaller reduce the motor speed because then it will just go back and fourth.
