Laser-based weeding robot

Today, the only alternative to herbicides in agriculture is a combination of mechanical hacking and hand weeding. To make scalable organic farming possible, technologies are needed that greatly reduce the use of manual labour. Thanks to its laser-based approach Caterra’s robot allows the removal of weeds which are in close proximity to the crop, something mechanical methods are unable to do. Small, lightweight and chemical free – with Caterra, Aurel Neff and Patrick Barton will lead the way to a more sustainable agriculture.
