I want to see details on power source and energy usage. That's where I'm a bit skeptical. To do the 20 acres they're talking about you'd need one hell of a huge battery, assuming it's electric. Even just to move the thing. Then add power draw for the laser on as well. Also seems odd to have it be something that is self-powered and autonomous rather than just something you pull behind a tractor on the three point hitc…

I love the application of lasers to address this problem. I think there are a lot of applications for this tech - lasers to kill flies in factories and mosquitos in yards. I'm curious if it can be used to tackle Australia's field mice problem which is causing tens of billions of dollars a year in damage.

Why would you assume it was electric?

Earlier quoted context omitted.

"I want to see details on power source and energy usage. That's where I'm a bit skeptical." Meh. Worse case you could even have a wire.

Hell, you could probably stick a fuel tank and a generator on it if you had to.

Check the Features & Specs page [1]

    74-hp Cummins diesel QSF2.8
    4 hydraulic drive motors
    75-gallon fuel capacity
I'd bet that diesel also powers a generator to run the computers and 150W lasers.

>Also seems odd to have it be something that is self-powered and autonomous rather than just something you pull behind a tractor on the three point hitch That doesn't seem odd to me at all. The whole point of this thing is to let it run all day killing weeds while you do other stuff . The fact it only has a max of 5mph (and likely significantly slower when there are actual weeds to kill) means you would spend all day…

There's a lot of automated tractors now

https://carbonrobotics.com/features Lasers are 150 watts, so a small fraction of the power draw. Seems like getting the automation is key, replacing herbicides would require multiple passes over the same ground.

150W of output power.

Lasers are notoriously inefficient, CO2 ones are in the 5-20% range.

So probably at least 1000W for the lasers, assuming 10% efficiency.

Given where ML and CV are today, I'd bet on open source models trained on weeds within 3-5 years. This company can scale, but their unit price is going to plummet. Also, it sounds like they're using cameras, where it's concievable that other future sensors could be more efficient. An iteration of this with higher resolution cameras and small flying drones seems like an intuitive next step. This is a super interesting…

Commodity drown with high powered laser for killing things based on image recognition sounds like sci-fi dystopia.
