You have some odd thoughts.

But solar technology would probably have to be increased to make that viable. Not for the pi, but the mechanical aspect would need some decent power behind it, and even in accumulate-and-burst mode might be a chunky thing. Wind wouldn't work once the crops got up above a certain height, but less hoeing needing then anyway.

But in developed country, the problem has already been solved extremely efficiently with chemicals. Even for the organic boys this is a quick task done with tractor and very wide cultivators.

Third world? Maybe, but then labour's cheap there, and more reliable. Sorry to be negative. :(

In the spirit of Jethro Tull it occurred to me that its time to bring back the horse plough:
Tull revolutionised farming by introducing the seed drill and matching hoe - the seed drill laid out the seeds in nice parallel rows and later 99% of the weeds could be killed by the skilful driving of a hoe between the rows of growing crops.
Labour costs and cheap weedkillers and bad driving have driven out the practice. Surely modern technology can produce an automatic device to do the hoeing. All it needs is some way of accurately recognising the gap between a row of crops.
I'd imagine the Pi with a camera is probably up to this - and controlling (with a pre loaded field map) a small hoe to wander up and down the fields using solar and wind power?
Anyone know of any Pi optical groups?

I use a wheel hoe - less that 100W at walking pace for about a 10" cut. Modern technology - wonderful - modern industry corrupt. Chemicalstop working after two or three years and - if this can be made for around £1000 (not inconceivable) then it will pay for itself in a couple of years.
