I'm not sure Jeff is going to be here Today but I'll go ahead and Make a brief update Um just from a status standpoint I'm able to get Um Sentences GPS and sentences into uh By tractor and it's publishing the fix Statement which is good That I ended up using The Ross version of the nmea navset Driver the Previous one That had been updated a bit Couldn't get that to work I was getting At the beginning Just a generic Driver failed Statement And it made reference to the logs I went Through all of the logs Um And couldn't Seem to find out what was Going on I had a suspicion it had to do With Python 3 Um Issue but I was never able to confirm Or deny that but anyway I've got the Generic version At least on the surface Working that took a little bit of doing
Too had some cat can make errors uh Specifically this Needed to be installed after that I had Issues around An import serial statement not working Again I suspect it has to do with Python 3 but Was able to fix that with Installing the Python 3 serial then a Permissions issue On the Port itself was able to get that Resolved By adding My user id tractor to the dial out Group at least that's what I think the Fix was Um And then was able to Launch That launch file but was not able to do That with Without using the whole Path name and before you ask yes the Bash RC contains Those two statements which is The only reason I could think of that Um I would get this error that it's not A launch file So um It was just some of the error messages That I received And then ultimately was able to um Display the various sentences as they Came across
Um Before I talk about oh Dom let me share These are The Ross agriculture Driver dot pi Script And this is the Ross version of the same Script what you'll see is There may be other changes these are the This was the primary one that I could Find Um If the if there's a fix Then This is the same until about there and Then this else if GST Shows up Here So This information is new or added to the Or else agriculture version And Seems to be about Working with quaternions and Publishing This current heading although that Current heading Does get published Um Here but it's not In you know it's just pulled this is Pulled up For some reason I don't Exactly remember why Matt may have done
That Um So anyway that's one of the material Differences between the Ross version and The Ross agriculture Version there was also There's also an Uncommitted change Having to do with this status Um That I looked at briefly This GBL gbas has to do with Ground-based augmented Status and SBS sbas has to do with Satellite-based augmented Status so for some reason Matt thought Well again not committed at one point in Time was thinking that needed to be Changed Uh uh so I am getting a status of two Um On my Output Which I believe is an rtk fix because I've Turned on my base station as you Wouldn't look it up guess On Odom Um Remember I'm working with a new laptop So I have to sort of start from Scratch from something so I've Inset set up or udab rules for my left And right out on boards I've cut data
Coming from my left Odom TZ my right Is not giving me data for some reason so That's the status that I've gotta unpick And this is what my udep rules are Looking like at the moment I'm just Using the Um Physical position on the USB Board and at the moment Um Seems to be fine and you might say why Is that one Different it's what Was output Um So we'll see If that has anything to do with the Issues so my next Step at the moment is Um Let's see there's differences determine If I need them and connect the Odom for The rear wheels Install what I refer to as Jeff's Simulator On the tractor laptop This is um Let me go back to my notes Jeff had provided a separate catkin Workspace Back when he was working on Simulator And these are some instructions on how To download that and install some other
Requirements and then um Change the execution And then Launch the vehicle and um Drive it around That's Anyway that's where I'm at at the moment
