How does our technology work?
Weed detection
Our deep learning algorithm divides an image into crops, weeds and soil. The vegetable plant (in orange) is given an additional protection zone (in blue). This prevents the leaves of the crop plant from being affected.
All row crops can be recognised. However, we need a sufficiently large data set with images from the various growth phases and weather conditions for each one.
Laser Treatment
Before
Published on the 30.Weeding Conference in Braunschweig (2022)
After
The laser technology allows a biological treatment of the weeds without any chemicals! The plant is heated and dies in the following hours.The weeds are not pulled out and the soil is not disturbed. If the plant is wet, it needs a little extra energy but the effort is manageable. Together with Agroscope, we showed at the weed conference in Braunschweig at the beginning of 2022 that permanent removal is not a problem.
Rover
Our robot platform is completely electric and comes with its own charging station. The weight is deliberately kept low, the robot generates less compression per wheel than an adult human. This allows us to go back into the field early after rainfall.
Mass: 300 kg
Track width: 1.5 and 1.8 m
Weel width: 0.2 m
Weeding speed: 80 m/h
Battery capacity: 16 - 24 h
Autonomy
The robot is fully autonomous and navigates the field precisely and efficiently using GPS and camera technology. All you have to do is set the field boundaries once on the computer and the robot can start and is ready for use around the clock. You will receive timely notifications when a battery change is required to ensure uninterrupted operation. Thanks to its low speed, the robot also poses no danger to humans or animals, ensuring safe use in the field.
