This is the routine thread where we discuss what you'll be working on this week! A cool robot? A computer vision project? Something cool in reinforcement learning? 3d printing a drive train? Let us know!

Maybe instead you're studying something, or reading a paper that just came out? Post about it!

It’s also okay to say “nothing” too - it’s great for your mental health to take a break!

Looking for help? Ask a question! See someone working on something cool? Ask them about it! No project is too small or too "newbish"!

Thanks for your interest :) This is a full scale vehicle project which I participated in its development during my PhD. All my lab colleagues put their own package based on their specializations (perception/decision/control). It actually began as my hobby project when I was frustrated with the lab's legacy MATLAB+LabView based SW and HW. I am now working in a startup company that bought the technology from the lab.

The code works, but the code quality suffers since it's been developed by newbies(most of the lab members are from ME background so their computer skills aren't stellar, and this was everyone's first rodeo with ROS) so the company's goal is to clean up and refactor the codebase while we are updating the system to a modern ROS version. Sadly the company is still small and I hope we get more people on board to speed up the process. On the bright side, I have a lot of opportunities to contribute.

BTW I totally agree with what you mentioned about Python. The old codebase is using ROS melodic which still supported Python 2.7, which makes things even harder. I also have to check if the dependencies are met in new Python versions while updating the code to 3.x versions. One more problem is that when we are deploying our code in our clients' systems we wish to hide our source code as much as possible but Python packages are posing to be a problem in that aspect. I would be happy to hear some tips regarding that issue. Most of our C++ code is fine, but many of our homemade packages are mainly Python scripts.

Oh yeah, MATLAB is painful. I get why you use it at first - it's great for handling derivations for you when looking at control code, and handles matricies well enough when learning kinematics. But once my homeworks started to demand animations and complex processing I yearned for a language with classes or any advance features at all. Still, managed to make some cool stuff - like this RRT path planned transmission removal 😄

What startup (assuming you're out of stealth mode?) Good luck with the jump over to a startup. It's rough but hopefully you knock it out of the park.

As for code deploy - I've worked on the problem at two startups now. I can probably advise you on some stuff to look into, but would need to know more about the problem space you're specifically looking at. Though I'm hesitant to mention full obfuscation if you're not delivering a finished product but rather a module to the end customer.
