Row crops and monoculture could present interesting automated harvesting opportunities
For example, here’s a mechanical harvester for microgreens.
Right now, it uses manpower and a hand drill for power (simple, great solution) but to scale it up… It probably wouldn’t take a whole lot to rig something like that to a track system and then just sense for approximate cutting height at the blade on the Z axis. For crops that are ‘felled’ rather than dug or picked, the right planting orientation could probably make a system like that workable on a small enough scale to be accessible to independent growers.
