We used a bug algorithm(possibly the worst computer science name ever) this year--but it was based on camera data, not tactile. We ended up using a method like that in the original DARPA challenge--finding deviations from the white field surface and flagging them as obstacles. Our bot was originally programed to get to our player station or outpost, but in the actual comp it rarely got there due to too big of a jam-up in the middle of the field(still better than trying blindly to get into position and getting stuck though)
