Now it's down to business. Collect balls, sort them, and putt own balls into the holes and block those of the opponent. This is the task at the 2006 EUROBOT.

The international robot competition, 2006 Eurobot, focuses this year on the game of golf. For the third time in a row, the TU Chemnitz students have faced up to the annually changing rules and got down to work with high motivation.

The rules of the game

14 red and 14 blue holes are distributed over a surface of 2 x 3 meters. At the start of the game, 15 white and 2 black balls are spread on the field. Four positioned totems supply the balls, each of which feeds four white and two black balls into the play.

The task of the autonomous robot is, within a play time of 90 seconds, to fill as many of one's own holes as possible with the white balls in the opponent's half of the field and to block the opponent's holes with the the black balls so that no points can be obtained. Each team is free to empty the holes filled up by the opponent with the black balls and to fill them up with the white ones to get points. Each team is allowed to field just one robot - naturally under compliance of certain dimensions and rules.

The requirements

Quickness, precision and an intelligent tactic are called for besides the stable power supply. The 17-member project team, primarily students from the faculties of electronics and informatics, developed a robot with a "brush system" to increase the chances of winning.

The chain-driven robot, while crossing the playing field, collects the balls lying here and there through rotating brushes. A meticulously programmed system situated in the interior of the robot enables it to locate the balls on the field, collect them and sort them according to their color. Moreover the robot should distinguish the holes on the field by their color and their status - free or occupied.

The CAD design of the TU Chemnitz. The students want to get to the international finals in Sicily with it.

In this case, the balls are moved up to the holes by a carriage design (comparable to the ink feed system in an ink jet printer).

The carriage, which the Chemnitz team sent to the race, is mounted by iglidur G^® bearings from igus^®. The bearing is exceptionally suitable for extremely high loads at low to medium speed. Numerous swivel and rotary movements are among the basic requirements of the robot. These can be executed by the high performance bearing.

After the national qualification round, a maximum of three teams go up for the international competition, the 2006 Eurobot^open in Catalane (Sicily).

igus^® is thrilled and keeps the fingers crossed!
