I heard about this some months back, it is a logical step towards multi data point field monitoring & limiting weed killer use.

But the GPS units for farm kit are expensive targets for thieves meanig adding more layers of yard protection to farm kit, which amouns to a lot more than simply locking something behind a padlock in a barn.

"In one case, NFU county chair for Lancashire Lisa Edwards fell victim to tech-savvy thieves. Although tractors were housed in an alarmed barn, Lisa was unable to remove the GPS dome from the combine. It was stolen alongside the screen used to operate the combine. It had huge consequences meaning harvest was delayed while a temporary screen was fitted. Altogether it cost nearly £10,000"

One night of drillingout tractor locks & stealing kit = £100,000 of damage.

I wonder how it recognises weeds.

Videocameras (with different illumination/filters) and artificial intelligence?
The software is presumably bespoke and worth a lot of money.
