Check out the EXPO21XX University Robotics Exhibition site at
This online exhibition site showcases nearly two dozen university robotics research centers worldwide and their research projects. Each entry gives basic information on sample robotics projects designed by that research center (many student projects), photos, videos as well as contact information for that research group. I think you will find some good ideas for your own projects here. And if you are thinking of going to graduate school, you may find ideas for where you would like to apply.
