7. How is the accommodation during the event?
We will provide free low budget accommodation for all members of the teams. There will be 6 large tents with camp beds for each student. Please bring your own sleeping bag! For the girls there will be a separate compartment. The accommodation will be on the DLG farm site close to the Field Day area and the contest field (10 min walk).
There will be toilets and showers close to the tents.
6. Where is the registration?
The registration office is close to the accommodation on the DLG farm site (Am Gutshof 3, 06406 Bernburg - Strenzfeld, phone +49-175-4421359). This is outside the DLG Field Day area. When you register each student will get a name badge and a ticket for the Field Day site.
If needed you get a car ticket for going by car onto a FRE reserved parking lot beside the contest area (for transportation purposes and final parking). For going back to the accommodation please WALK! You can also use your car for storing tools etc., because it will be close to the FRE area.
Breakfast will be served each morning in a farm shed close to the tents (empty grain storage). The shed can be used by us for storage purposes. In the shed we will have our registration office during the event. It is the contact point for all issues during the event.

3. What about the "weed" detection in task 3?
Q:
1. How close are the weeds / golf balls to the robot?
2. How many cameras are allowed?
A:
1. The balls are placed within the crop plant rows between plants.
2. The number of cameras you use and on which side you mount it is up to you. However, the robots should navigate to each second row - not the adjacent row - in order to fast pass through the rows and detect all the possible 'weeds'.
In the following links you find the type of the golf balls that will be used in task 3
