It's spelled Ecorobotix (I work there :-)). We have two machines, ARA a mounted-sprayer and AVO the solar powered autonomous weeder you are talking about.

Ask me anything ;-)

Anything? :D What does your stack look like? Do you use ROS or something more in-house?

something more in-house, mostly in C++.

What herbicides do you spray?

How much will Avo cost?

It's funny too look at the difference between the "See and spray" demonstration video and the "Robovator" video. The "See and spray" video feels very corporate, with lots of 3D renders and piano music and marketing actors making awkward jokes. The "Robovator" video is to the point, only shows on-the-field live videos, with no music and barely any flourish, to the point of being incredibly dry.

I wonder which one would work best on farmers. The corporate one feels more polished, but the simpler one feels more honest.
