Weeding robotic platform

Targeted application of herbicide by the first ever completely autonomous robot for ecological and economical weeding of row crops, meadows, and intercropping cultures.

100% autonomous

Solar powered with rechargeable batteries. Can treat up to 10 ha/day.

High precision

High precision spraying. No crops affected, no loss of yield.

90% less herbicide

Less herbicide used. Reduce your costs and your environmental impact.

KEY POINTS

Our autonomous robot represents a major innovation in weeding methods.

  • Autonomous

  • Detection > 85%

  • Solar powered

  • Easy to control

  • Easy maintenance

  • Lightweight

  • 4-Wheel-Drive

  • Up to 90% less herbicide

  • Up to 50% less expensive than standard treatments

  • Improved yield: no herbicide left on the crops

  • Conserves the organic life of the soil, with limited soil compaction

HOW DOES IT WORK?

Avo performs autonomous weeding operations in plane fields and row crops. Using cutting-edge machine learning, the robot detects and selectively sprays the weeds with a micro-dose of herbicide. The centimeter-precise detection and spraying reduces the volume of herbicide used by more than 90%, while ensuring crops are not sprayed for yield preservation.

Avo operates entirely autonomously and is powered by solar power and rechargeable batteries. The user can introduce field boundary and crop line information in the user interface software. The system then generates a navigation path considering field constraints and user predefined inputs. Combining GPS RTK positioning and visual navigation, Avo navigates with a high degree of precision, ensuring minimal crop roll over.

The four-wheel drive system enables the robot to clear obstacles and operate on slopes commonly encountered in cultivated crops. All four wheels can be steered independently, resulting in high maneuverability of robot and short turning radius, and thereby minimizing non-treatable field areas.

Due to Avo’s speed, a standard throughput of 0.6 ha per hour can be achieved. The robot can also operate during the night, further extending its daily throughput. Depending on solar illumination conditions, battery recharge, and terrain conditions, the robot can treat up to 10 ha per day (­including night-time operation).
