Obstacle avoidance with an UGV -HELP PLEASE-

So the whole reason I started this project was for a program in my high school called the Authentic Science Research Program. I'm not sure if you've heard of it or not--we apply to the Intel talent search senior year. I'm currently a junior. Currently, I want to do a study on something in the robotics category, but it looks like I'm going to study obstacle avoidance. Does anyone have any ideas for a research topic for me? I need some sort of "question" that hasn't been answered or something that has never been done before. Maybe create a new obstacle avoidance method, I'm not sure---but any ideas?
