4. Removal of objects

General description

For this task, the robots are navigating autonomously. The robots shall remove 10 objects and place them outside the crop area on the headland. Task 4 is conducted on the area used in task 2 and task 3 with straight (!) rows. The exact relative position coordinates of the objects will be provided beforehand as a realistic scenario using a drone with a positioning system and a camera. The object type will also be provided. The waste / cans (5 objects) should be placed on one headland and the weeds (5 objects) on the other headland. There will be an indication of the field reference points using a QR code and a pole.

Virtual Field Environment

The different objects are placed between the rows. No objects are located within rows and on headlands at the start. The weeds and beer cans will be randomly distributed across the field. So they can be in between and in the rows. No objects are located on the headlands. The weeds and cans will not be connected to the soil, but will differ in size and mass.

Rules for robots

Each robot has only one attempt. For starting, the robot is placed at the beginning of the first row without exceeding the white line. The maximum available time for the run is 5 min.


The Jury or the simulator registers and assesses the number of objects where they are remaining after the run:

Object picked up 3 points/object
Object delivered to the right headlands 6 points/object
Object delivered to the WRONG headland 3 points/object

The robot is allowed to push the object to the headland, but without a clear act of picking up, it will only earn points for the delivery. Crop plant damage by the robot will result in a penalty of 2 points per plant. The total travelled distance will not be assessed. The task completing teams will be ranked by the number of points as described above. The best 3 teams will be rewarded.
