missing romi-back-castor.stl in romipi_description/meshes/wheels/

[archie1983]

romi-back-castor.stl file seems to be missing in romipi_description/meshes/wheels/. When I try to bring it up, I get this error:

[ERROR] [1642774881.506015757]: Could not load resource [package://romipi_description/meshes/wheels/romi-back-castor.stl]: Unable to open file "package://romipi_description/meshes/wheels/romi-back-castor.stl".

Please add the missing file.

Hi,

I added the file, but I'm concerned it's from a different version of the model. I currently don't have a working test setup, can you let me know if this works and makes sense?

Thanks, Peter

Please add the missing file.

Hey, thanks for that.

Ok, I did find a romi_castor.stl inside src/romipi_description/meshes/bases/. After renaming it and putting it in the wheels directory, the error is gone and it kind of shows up in the model, only shifted to a side- not quite where it is supposed to be, but still on the chassis. So I've been making do with that for a few days now.

The new STL however- the one that you just added- shows up huge. I need to zoom out so far that the robot is not even visible anymore, just the caster.

Please see images attached.

Other than that- thanks for the effort. I'm still going through it one project at a time to understand fully, but this is awesome. I ordered a LiDAR and raspberry Pi today to put it all together on my RoMI and hopefully get it all to work. Thanks!

Hi Arturs,

Thanks for letting me know. I've updated the git repo to reflect that file being in the wrong folder.

If you want to dig into it, the romipi_description/urdf/romipi.urdf.xacro is where the offset is configured. If you fiddle with those values, you can probably get it to line up.

You may have noticed that the model sometimes "bounces." I'm not really sure why this is happening and I'd be interested to hear back from you if you see anything.

I'm sorry to not be able to provide more support right now. The new semester is starting and I don't have as much time to devote to this as I ordinarily would. I'm really glad to see someone interested though.

Thanks, Peter
