Well, first, I wouldn’t assume we’re all sirs.
Due to time constraints we don’t publish every potential intern project. We’ll try to match up student abilities and interests with projects we wish to complete. I have two bits of advice I give to all my students:
Apply to everything that interests you; let the mentors/hiring manager judge if you are “qualified”. Early on in your career I don’t think it is wise to censor yourself based on your own beliefs about a project. Sometimes interest, determination, and aptitude are more important than qualifications.
The best way to get ahead is to try and contribute to an open source project. This let’s mentors get familiar with you and your capabilities; and it let’s you get more familiar with open source development. If you are already using a few ROS packages that’s a great place to start.
Other than that I would look to recent and future ROS and Ignition releases to get a sense of what we’re working on or will be working on in the future.
