Illegal value 58 in argument ChPos

[bwoodsmec]

Hello Jose Luis,

First off, thanks for your hard work on this project; it was interesting to see Nathan King pop up in your acknowledgments - I worked with him extensively during grad school on one of my older projects.

Back on topic though: I am having issues setting up machina bridge for my new IRB 1300 with the omnicore controller (w/ EGM and multitasking). I was able to load the driver files (after changing the extension from .mod to .modx and modifying the call out to that effect in the .pgf) and run it on the flexpendant. After starting it up, I was able to get machina bridge to connect over both the MGMT ethernet port (192.168.125.1) and over WAN, but as soon as I try to send a command from machina the program crashes with:

Error 41449. "Illegal value 58 in argument ChPos. Program ref:/Machina_Driver/ParseStatement/StrFind/739."

I've tried move commands and speed commands to no avail. Any ideas here? I attached a screenshot from machina below. Thanks so much!

Hi @bwoodsmec , and thanks for your kind words. Happy you know Nathan :)

I have never seen that error, looks like there is a problem in the driver reading your messages.

Which RobotWare version is your robot running? Can you replicate the same error in a RobotStudio simulation?

Hi @garciadelcastillo,

It is running RW 7.5.2, and yes, the same error is present with a virtual controller in robotstudio

Hi @garciadelcastillo,

Following up on this: I recently dove back in and am having the same issue. I've done some debugging which may help us figure out what is going on here? I connected to your grasshopper plugin and ran the vertical line program. This is the queue on Machina Bridge:

As you can see, it did the message fine, then threw the error on the SpeedTo message. I had the driver mod output the s and st:

Given both 'Message' and 'SpeedTo' are 7 characters, I would expect s to be 7. This is true for message which spits out "@1 7 "Let's do some robots!";", however, SpeedTo spits out "@2 4 70;". This means it believes the string is only shorter than it actually is, so when it tries to go to the 9th position (SpeedTo(70)), it throws a runtime error as ChPos > length of the string. Any ideas??
