Hi,
We have checked and everything seems to be in place. When we calibrate the controls they flash green for 2 seconds, then go back to flashing orange. I don’t know if that means anything, but I was thinking that meant that there was nothing wrong with the wiring.
Also we got our robot to move by disabling the safety config in the program for the motor controls, However; I don’t think that’s the right answer.
That tells me the problem is in the code somewhere. Are you using LabVIEW? Are you periodically setting the motor value (i.e. every 100 ms or so)?
It seems like your program isn’t updating the motor values when it’s at zero. If you are able to calibrate but than it goes back to flashing orange that probably means motorsafety is killing the outputs for some reason.
If you only update the motor values if the joystick value changes, that might result in this type of problem.
Are you establishing all of them as Victors and not as Jaguars in code?
We are using labview. I don’t now if we are setting the motor values, how would you check that?
If the problem is with updating motor values, what needs to be changed in the program?
They are established as victors.
Hi Tina,
If I recall you are the rookie team that we helped get going at the 610 quick build?
If that’s the case my email to you should help. At the present, I really think that either the PWM cable(s) have been unplugged and or you have not enabled the robot.
I hope the email helps.
BTW.
This is a wonderful place to get help, Chief Delphi that is.
Hi,
We did receive the email, and checked all of the components you stated but the light is still flashing so we are inclined to believe its a programming error. We even had a mechanic and an electrician look at our robot and neither of them could see an error in the wiring.
Do you know of anything we should look for in the program
Thanks
Can you post screen-shots of your Begin.vi Teleop.vi and Finish.vi?
[strike]Everything[/strike] A lot of what you describe is consistent with an improper PWM cable connection. It takes practice to be able to insert a PWM connector into a Victor properly every time. Unplug one and inspect the pins. They should be perfectly straight. If any are bent, it’s likely that it wasn’t making proper contact.
Is the dashboard installed, operating and enabled?
LEDs will flash orange until the robot is enabled … right?
We have been using the basic code, except in the begin VI we changed the safety config to disabled and the Jaguar to a Victor.
It is Flashing orange unless the robot is moving, then there is no color.
Now that sounds like a Victor calibration/joystick centering issue.
The orange flickering light might mean that neutral on the joystick is right at the edge of the Victor’s neutral dead zone.
That’s not a dangerous condition, just annoying.
With the robot up on blocks can you push the joystick to it’s extreme’s and see the Victor status light turn green in one direction and red in the opposite direction?
So how do we fix that?
Does the code deploy without errors?
Can you Enable the robot from the Driver Station?
A screen shot of the Enabled Driver Station will help us solve your problem. Example, either take a digital picture or in Windows use the print screen function and then paste the clipboard into Word and attach the result here.
The Calibration instructions are on page 2 of the Victor 888 User Manual
But are the motors still not running even though the Victors are going from flickering orange to off when you try?
Or is the robot moving, but you just have a flickering orange status light when it’s supposed to be at rest?
We didn’t see any change in color when we pushed the joystick, there was no colors.
The motors do not move when the safety config in the program is enabled. When it is disabled the robot moves. The light flashes orange at all times unless the robot is moving, then no light is displayed.
The motor Safety is because something is slowing down the cRIO program or the communication packets.
You can run without the Safety if your controls remain responsive. If however you are experiencing any lag, then it becomes a higher priority to track down the cause for the slow down.
The flickering orange/no lights pretty much describe a calibration issue.
On the Dashboard there is a display with a green dot showing one of the joysticks movements. Does that green dot go all the way up or down when you push the joystick all the way forward/back?
And is the green dot centered when the joystick is at neutral?
