Shortening supply lines is a rather silly goal. It doesn't really save anything.

> It doesn't really save anything. It doesn't save time? Oil? I don't understand your reasoning here.

It doesn't save a significant amount of time or oil. Not enough to count anyway.

Almost nobody who loses their job wants to. It's still a net win for the economy as a whole that people lose the jobs that are no longer worth doing.

The economy as a whole does not matter. It is not a person, it does not have any moral or ethical value. The only people who benefit from "the economy as a whole" growing are people who have positioned themselves as parasites who extract wealth from everyone like bankers. People want healthy, security and happiness. "The loss of your job, home, lifestyle, culture and heritage is irrelevant. Move to generic urban cell…

Go out on your own and the a mountain man in some remote place and live on cheap land. Then you can take your health, security and happiness into your own hands.

It will be much harder for people to extract wealth from your investments if you have none. It will be much harder for the government to tax you since you have very few things to tax.

I know it takes capital to start but that is the world we live in. Everyone has already claimed everything. The system is world wide and looking to expand to Mars and space. (unless you move to Alaska, I think they still give free land away)

No, you really can't. If you are white and try to create a self-sufficient rural community you are going to get Waco'ed. But even if that were not the case, it doesn't help any of the people we're talking about. Some random farmer or coal miner is just getting buy and has no way to buy land and fend for himself. Without his job that everyone is so desperate to take away from him, he can't keep paying the loan on the scrap of land he has now, how's he going to buy "cheap land" in "some remote place"?

What precautions do you need to maintain eye safety around these bots? Can lasers kill weeds at the root, or do you just keep them "mowed" down to size with repeated applications?

A skirt around the laser.

There’s a few techniques. You can cut the meristem or you can heat the weed. If you can explode the physiology, they don’t grow back.

Cool. How does the laser kill the weed without risking starting a fire that might damage the crops?

Not the OP, but I'd just point out that all you should need to do is get the stem above the boiling point of water, which is well below the combustion point. What wavelength to use for that could be an interesting discussion. Makes me wonder whether you could use masers (microwave lasers) rather than optical lasers for a more efficient "heating the weed from the inside" effect.

Yup. There are peaks for energy transfer into water around 1 and 2 microns. So mid-IR.

How efficient is laser weeding in time and energy? Like, can the robot move down the row as fast as a human weeding by hand? Can it carry a car battery and weed for an eight hour shift?

Not OP, but my take on this is efficiency and quality will be superior to a human (or will be very, very soon). Speed of movement / detection / destruction cycle isn't as important as cost per unit of land patrolled - these are things you can easily scale up if the price per device is low enough. Compare & contrast cost of humans.

Right now the dwell time of the laser is slow like in the order of a second per weed. And there can be hundreds of weeds per square metre. So this needs to improve — and there’s lots of good ways to improve it. However, as the parent says, just leave a few bots out there and you easily compete with human operator cost.

Hi! Would lasers work for Bermuda grass infestations? I am forced to till sections of my organic field to get rid of them and I would like to go no-till as far as possible.

Maybe have a look at Rootwave — electric weed killing that’s used for invasive grass.

What kind of remote operation/visualization interfaces do you have for deployed systems? Does your company receive the alerts/visuals/notifications or do the farmers that buy from you receive these? Do you want farmers to eventually be able to operate the fleets you sell them, or would you prefer to sell the entire operation to farmers and manage the fleets yourself?

Farmers may not fix them but they will operate the robots on farm. Already, tractor drivers are skilled operators of GPS controlled semi-autonomous machines. They’ll be the people who drop the robots off, review their task plans, stay in range of their heartbeat, swap implements and refill stuff.

I've been thinking about a suite of robots on the residential level that could not only mow the grass and edge it, but also shovel snow, and perhaps eventually prune plants and pick the harvest. Would such a suite (or a base plus a suite of attachments) be practically affordable soon (say, cost less than $5k retail)? Edit: oops, I guess this should be directed at the small robot company, not the space bots with laser…

Depends what you mean by soon. And how multi tasking it is.

But price erosion in the parts is dramatic and the software baseline is rising.

What is the cost per acre / hectare of an intervention pass?

So many variables. But say £100 per hectare as a ballpark / rough order of magnitude.

Note that the laser weeding in the article is researchware — not a commercial product.
