Can you upload the files for the other robot? 3151?

I've been considering writing something generalized in the offseason, but I haven't been able to get ahold of a second RoboRIO to bring home myself and build test cases on... The idea I had was to write a 3D simulator environment and a proxy implementation of WPILib so you could compile the robot code into a DLL. The Gazebo thing was cool, but being Linux only kinda ruined it since it wouldn't run very well on a VM.

Wow, I missed this thread somehow. Anyways, I was intern for Autodesk and while I was there we worked on exactly this, a program we call "Synthesis":

It has a few parts: An Inventor plugin, which runs while your robot CAD is open and utilizes a path-search algorithm to intelligently simplify and link together meshes based on joint data from your CAD, and create a 3D representation of your robot which we import into our game simulator. Once all this data is extracted from your robot CAD, we have a GUI that shows detected joints, and allows you to place motors/pneumatics/sensors on them and assign ports to match your code (e.g. if you have a revolute joint, you might specify that it has a motor on it, controlled by "port 7").

Next you simply run the game simulator and import your robot into it.

Finally there is a loopback adapter and modified wpilib (we have support for c++ and java and working on labview iirc) that allows you to emulate having a crio/roborio so you can control your simulated robot through the driver station (and using 99% the same code you would on your real robot). The simulator receives control packets from the driver station and emulates your robot real-time.

I can't give an expected release date or anything, but the processes I described are currently implemented in a mostly functional Alpha. Second wave of development on it will begin this summer, so look out for it.

This is amazing. Best of luck on that project.

Is there a way to compile Java code to a DLL callable with C bindings, or do you run an embedded VM?

The Java Native Interfaces feature of Java might offer what you are looking for.

i remember that during the PNW Champs. i really want to get my hands on that .stl converter...
