Please Help: Sporadic operation: Electrostatic: Noisy Supply getting on rio?

[mbone206]

Hi All,

Team having major sporadic operation, need fix ASAP, not sure if this belonged in Electrical forum...

Drive would periodically have lag and when idle, make pop corn sounding noise on its own (solenoids)?
I stopped believing it is code at this point (LabView). Moved everything out of Teleop except TankDrive and setting Globals
from JoyStick. Intstalled Elapsed Time VI, teleop will jump all over, 10mS as high as 400mS, without operation, just hit enable.
I believe it must be electrical interference at this point, not much code in teelop, not even driving robot (I know teleop
has to be <20mS). Error indicated something can be hogging it's resources, but verified no other motors assigned to Tank Drive
PWM.

1) Electrical Static: This Robot does build up a lot of static. read several threads about putting wire from chassis to ground
* Several opinions if legal this year, has anyone confirmed this is legal with documentation
* Static build up also from belts, using over counter antistatic spray, I believe there is a better industrial
liquid spray to use on belts, has anyone found best antistatic spray to use on belts
* Grounding: What is best way to Ground, here many opinions in links.. and what is legal.. Ground motors to chassis?
Need to isolate supply ground and Rio from chassis?


2) Caps?: Does anyone use capacitors across motor terminals? Has this helped? What value do you use?
Power Supply: Does anyone ad addition caps on power supply line? I do not have an Oscope to see
noise on supply line possibly getting on Rio supply, but thought this could cause sporadic problems?


Any other suggestions? Did try and comment out sections of code to eliminate problem, did have some improvements but
never 100% repeatable commenting out same section of code

Thanx for your support
Mark
