Ester's job is to collect small rugby balls at a 2x3m field. It has been built for Eurobot 2004 competition and it ranked 4th out of more than 40 teams in the international finale in France. It tracks its position using Monte Carlo Localization merging information from shaft encoders and floor color sensors. It is able to shoot the balls to the goal from any position on the playing field. More information about the shooting mechanism and the control software can be found on the homepage (in english and czech).
