As an undergraduate, I was a member of the 2011 RoboCup 3D simulation championship team, the UTAustinVilla 3D-simulation team.  RoboCup is an annual international competition in the autonomous robotic soccer domain. My main responsibility on the team was coding the positioning and formation logic that our agents used.  With respect to positioning, I wrote an algorithm to dynamically assign the roles for each player, implemented a voting system to coordinate the players on the field, and added logic to execute a number of set-plays.  After winning the competition I co-authored a paper describing what we believed to be the components that most contributed to our winning team.  The paper was submitted to the 2012 Autonomous Agents and Multiagent Systems (AAMAS) conference and was accepted.  I also co-authored an additional paper focusing specifically on the positioning and formation system I implemented.  The paper was submitted to the 2012 RoboCup Symposium and was accepted for an oral and poster presentation.
