Re: Drivetrain PID tuning
This is a good point, and I feel it would probably solve a lot of out problems. However, I haven't found a good way to get real time plots from the robot. Do you just use the smartdashboard?

Re: Two USB Cameras
I was told at an event that the only camera that is tested and confirmed to work is the LifeCam. Anything else, and you're on your own.

Re: Drivetrain PID tuning
I think there was a misunderstanding here. I was talking about using a gyro/accelerometer (the navX in particular) to measure translational displacement, which we both agree is too inaccurate for...

Re: Drivetrain PID tuning
Of course I'm going to defer to you on this, but how reliable is displacement with a gyro? I'm skeptical.

Re: Drivetrain PID tuning
Sure you get a number that represents your angle, but if you're trying to go a predetermined distance, encoders make corrections much easier.

Re: Drivetrain PID tuning
Good point. I'm used to encoders because we use them for motion profiling, which you couldn't really do with a gyro.

Re: Using PID in autonomous to keep straight
Yeah but the issue is its unpredictability. For example, the ramparts tend to send robots in any direction, and there's no good way to predict that. Also, a couple inches can be a big deal,...
