Deploy GRIP without RoboRio?

Technical Programming
1

Hi,

We are trying to write the image recognition part of our robot using Eclipse, GRIP, and a webcam plugged into a Raspberry Pi. We have everything hooked up, but don’t have access to our RoboRio right now. When we were connected to our RoboRio, we ran by using the WPILib Deploy option. But this doesn’t work without the RoboRio. Is there a way to run this without it? We just want to test our image recognition code (i.e. read Network Tables from GRIP).

Thanks for any help.

Did you try these steps.

Yes, we have our GRIP Program done, and we are trying to integrate it into our Robot code. Looking at this page for Run GRIP from Java, it says we need to deploy to roboRIO first. We are wondering if there is a way to avoid this if all we want to do is be able to read the Network Tables from our GRIP software running on Raspberry Pi.

We followed these instructions to install GRIP on Rasberry Pi, and we can successfully see the streamed images in a web browser. But we are having problems running our GRIP program on the Raspberry Pi (it runs, but we are getting errors that we are trying to debug).

So you’re trying to preview the networktables outputs without a robot program, right? Check out the wiki page on using OutlineViewer for that.

Well, we want to test that the vision processing part of our Robot program is working correctly. We did see the Wiki page, but our situation is a bit different. We are happy with our GRIP pipeline and we have GRIP on the Rasbperry Pi. But what we want to see if the actual Robot code we are writing can read from the Network Tables produced by the GRIP pipeline on the Rasperry Pi (without having the RoboRio hooked up.) We can’t figure out a way to do it because it seems we can’t deploy without RoboRio.

The tutorial you pointed to works, but that is not using our program to read our GRIP pipeline. We want to test if OUR program can read from GRIP on Raspberry Pi.

Thank you for your response.

GRIP will work fine whether or not you’re running a robot program, but if you want to test if your actual robot code works, you need to run it. You might find what you’re looking for with FRCSim.
