Robotics and humanoid robotics & civilian drones discussion

The land is completely flat. Surely using a tractor with a boom sprayer does the job just as well.

Some argue that boom sprayers for example, capable of up to 40-45 hectares per hour coverage rates, are far more efficient than the DJI Agras T40 crop spraying drone (capable of 15 hectares per hour). This is true only when comparing one boom-sprayer to one drone. Drone spraying is highly modular and, considering the significant difference in capital and operating costs between the respective machines (a new drone costs approx. 5% of a self-propelled tractor sprayer), multiple drones can be seamlessly operated to achieve similar (if not superior) coverage rates to that of boom-sprayers, still at a far cheaper cost.

Another factor to consider is that, in a typical season, it will at some point be too wet for a boom-sprayer to access lands for spraying and it thus becomes necessary to hire in an aerial contractor to complete the required application. This service comes at an additional direct cost of around R200-R300 per hectare, which is over and above the already high capital and operating costs of a boom-sprayer. There is also an indirect cost to consider here, which is difficult to quantify, caused by the inaccuracy / drift associated with traditional aerial pesticide application.

The major kicker however when comparing the economic feasibility of boom-sprayers versus drones is that the tyres of boom-sprayers cause trampling damage and soil compaction. This results in crop loss of between 2%-10% (depending on tyre width) – which equates to an opportunity cost of R450 to R2,250 per hectare, when one applies the gross revenue generating potential of maize and wheat crops.

China's first domestic intelligent laser weeding robot has been put into use.

keep in mind that american company Carbon Robotics already produce this, so looks like HIT Robotics is catching up here.

something like this

They genociding weeds now?

I wonder if moisture in the weeds have impact on how effective the machine is. Probably would want to use it when it is fairly dry.
