Background and activities

Trygve Utstumo is an industry PhD candidate at Dept. of Cybernetics, NTNU. Since he graduated from NTNU in 2011, with a MSc in Engineering Robotics, he has been working with Adigo AS,

Adigo AS has Precision Agriculture as a main focus area, where the Asterix project is an important focus. Adigo cooperates with Bioforsk Plantehelse, NMBU, Yara and NTNU in several projects.

Asterix - Automatic weed control in row-crops

The Asterix project develops an autonomous robot for automatic weed control in row-crops. The system will only apply a fraction of the herbicide used in conventional application.
The Food and Agriculture Organization of the United Nations estimate that the worlds food production needs to increase by 60 % by to feed the growing world population. This cannot be ful lled by conventional agricultural methods on the worlds available farm lands.
Precision Agriculture (PA) is the concept of measuring eld variability and introducing this information as a feed-back to the crop management. PA can increase yields and optimize the resource inputs, and reduce environmental damages by avoiding excess use of herbicides, pesticides and fertilizers.
The Asterix project is an ultra-precise weed control approach, where individual weed leaves are controlled by herbicide droplets. The droplets are dispensed by an 18 cm wide array of drop-on-demand nozzles (DoD).
The Asterix project was presented at the 60th years anniversari of Dept. of Cybernetics with a poster, and received the "Best poster" award. The poster can be downloaded here.
