I would first describe what you want to do. Do you want to develop artificial intelligence? Perhaps develop mechanisms for robots? Are you interested in programming logic controllers (FPGA)? What about control systems?
These questions should reflect on what you want to do and where you want to go, not necessarily your present strengths.
Also reflect on how you fit into a team. Are you the one who comes up with the mechanism ideas? Do you find yourself excited about how to control the system?
Surely you can learn bits and peices of a system, but it is often advantageous to choose one area to focus your efforts in.
At the end of your college career, the projects you worked on will outweigh your classroom training and words on a diploma.
At the college level, one thing you could participate in is the Mars Society's University Rover Challenge
http://urc.marssociety.org/. There are countless other robotics projects going on throughout universities. Which school are you attending?
