Thanks, bit conflicted about it TBH, it's primarily/initially a weeding robot, although I do dream of expanding it to do harvesting, and yes potentially sowing too down the line.

Strapping something like the Jang P6 to it is probably feasible https://reagtools.co.uk/collections/jang

For the harvester it would be a bolt on for https://reagtools.co.uk/products/quick-cut-greens-harvester or maybe https://reagtools.co.uk/products/babyleaf-harvester-80cm (I grow green salads)
