Robot: WEAI
Task(s): Eliminate weed in and between rows
Development start: 2017
Pricing: Sell for €95,000 ($100,102 according to the exchange rate of 01-11-2023) plus a service fee


WEAI works with an extremely high precision, which is especially important in rows of vegetables. The robot has mechanical arms to remove weed between rows and a hoeing system to remove weed in the rows. In this way you also reduce the use of herbicides so farmers can reduce their costs and contribute to a healthier environment. Tests in Sweden showed that our robotic system can contribute to higher yields compared to conventional cultivation using chemical pesticides to control weeds.

Drive train type

Our Generation-3 robot has 4 wheel-drive and 4 wheel-steering. The robot platform will be updated for the 2024 season.


  • Specialised robot for weeding in row seeded vegetables
  • AI controlled mechanical weeding tool together with a passive hoeing system
  • Autonomous drive 24/7
  • Electrically powered with a battery swap system
  • Width 2 m and 2,25 m (bed width)

Navigation system

The robot uses RTK gps to navigate with 2 cm precision. Sensor fusion is also made with odometry and an IMU to get an accurate localisation. An AB line is imported from seeding together with field boundaries. A route is then created for the robot to follow. Obstacles are detected via two radar sensors attached to the front of the robot.
