Robotex 2008 rules

„Room cleaning“

Article 1: Task

Task resembles an ordinary room cleaning. The objective is to collect empty cans and dirty socks and move them to specified areas. Cans and socks have separate collecting areas. To make the task more challenging, some ELFA-catalogues are placed on the competition field.

Article 2: Field

Field is 3000x2000 mm “room” that is surrounded by 100 mm high white walls. Field’s floor is also white. Walls and floor are made of chipboard or of another stronger material.

Collecting areas:

2.1. Field’s two opposite corners are collecting areas for socks and cans. Collecting areas are in the shape of a right-angled triangle (i.e. a triangle with an angle of 90°), the legs (catheti) are both 700 mm in length.

2.2. Collecting area is separated from the other field by black wall (i.e. border, width 10 mm, height 10 mm).

2.3. 30 mm in front of the border is a black tape line (width 10mm). In front of the socks’ collecting area there is 1 line and in front of the cans’ collecting area there are 2 lines, which are separated by 10 mm. All measurements may differ by 10 % max.

Article 3: Robot

3.1 After activation, the robot has to act completely autonomously. Communication with other parties, situated outside the field, is prohibited.

3.2 The robot’s measures may not exceed 400x400x400 mm at any given time during the solving of the task.

3.3 The starting position of the robot is the border of the socks’ collecting area – the robot must be in contact with the border of the socks collecting area. The team is free to choose the robot’s direction. It is prohibited for the robot to place objects outside the field.

3.4 Because multiple robots may solve the task on different fields at the same time, the robot cannot intentionally disturb or damage other robots, referees or audience (such robots will be disqualified).

Article 4: Objects

4.1 Objects are:

a. empty 0.33 l cans of energy drink Battery (diameter 66 mm, height 115 mm);

b. black socks in size 42-44;

c. ELFA 2008 catalogues.

4.2 There are 6 cans, 3 socks and 3 ELFA catalogues on the field.

4.3 Catalogues are placed so that they are at least 500 mm apart from walls, collecting areas and other catalogues.

4.4 Cans are placed so that they are at least 100 mm apart from walls, catalogues, collecting areas, socks and other cans. The same applies to socks.

4.5 Cans are placed bottom-up, socks are fully stretched and catalogues lie on their backside.

Article 5: Beacons

5.1 Team may place one beacon in every corner of the field – total of 4 beacons. Beacon must be in contact with the corner. Team has 1 minute to place the beacon(s).

5.2 Maximum measures of the beacon are 100x100x200 mm.

5.3 Beacon can only be in communication with objects that are situated on the field (robot, other beacons).

5.4 Beacon cannot intentionally disturb other robots, cameras, audience or referees. Beacon or the placing of beacon must not damage the field.

5.5 Description of the beacon, including technical description, must be sent to the organizers at least 1 week before the competition. This is necessary to avoid that robots, which beacons can disturb each other, compete at the same time.

5.6 Beacons that emit electromagnetic waves must be given to the referees (switched off) at least 1 hour before the competition starts.

Article 6: Competition

6.1 Only one robot competes at one field at the same time.

6.2 Referees decide and fix the location of the objects before the competition. The location of the objects is the same for every team. Teams are not allowed to test on field with the final object location.

6.3 Every robot has 3 minutes to solve the task.

6.4 Every object that is taken to the correct specified collecting area gives one point. Object is considered to be in the collecting if it is placed so that it touches the floor of the collecting area and does not touch the floor outside the collecting area.

6.5 Time does not give any points. Time is considered only in case the robots score equal points.

6.6 The competition takes place in two rounds – first round and the final.

a. In the first round every robot gets two runs and only the score of the best run counts.

b. 4 robots that got the highest scores in first round qualify to the final round, where they all get two runs and only the score of the best run counts. The winner is the robot that got the highest score in the final round.

6.7 Number of registered members per team is limited to 5.
