Like the robots that replaced factory workers, the PR2 may be working towards replacing professors.* There is a list of graduate and undergraduate courses being taught with ROS and/or PR2s here. Soon the PR2s may be teaching the classes themselves. If your school doesn't yet have a PR2, you can order one here. However, I don't think you get to pick which professor it replaces.
* This may not actually be true.
