Well, it looks like I did it. I have gotten enough interest to restart a RoboCup team at The Johns Hopkins University.
We will be doing the mid-sized league. At the meeting last night, there were around thirty students who showed up. I tried to emphasize that it would have to be a decent time commitment, but most of all it requires a lot of self-motivation to set aside time to come into the lab yourself and work on stuff. At the end of the night, I ended up with twelve undergraduate students and two graduate students who decided they wanted to commit themselves to the team. They seem to mostly be CS people but there were also a few MechEs and ECEs, all of which I find necessary to compete in this league.
The next step for me is to secure funding for the team. We will certainly need it for parts for the robots, travel, entrance fees, and shipping the robots. (Any suggestions?) Supposedly we already have some old equipment and even a large lab space left over from the last time JHU entered. I wonder what condition everything is in... My expectations are not high, but it would be nice to have something that was at least working, no matter how slow or outdated it is.
Also, now I get to figure out how to balance a full-time job, take a class or two for part-time grad school, and do this. Advising a dozen undergraduates by myself and probably doing a large portion of the coding for the team is going to be interesting...
