Among biology, business, economics, and robotics, robotics is the toughest major or minor to find as an undergraduate.
Consider:
Carnegie Mellon University (also has an outstanding undergraduate business major)
Stanford University
Caltech (California Institute of Technology)
Cornell University offers a robotics program during the Summer
University of Washington at Seattle
Colorado School of Mines
Oregon State University
If you decide that robotics is not your primary area of interest, then look at schools with strong business programs as almost all colleges & universities offer biology & economics.
Life is about choices, not options.
