This startup says its new laser-armed weeding robot is already sold out for 2021

Carbon Robotics' new laser-armed weeding robot 'sold out' for 2021​

 

How many kWh of energy it spends for weeding 100 square meters of moderately weed infested field?

 

Well there's no free lunch but it may be worthwhile if the benefits outweigh the costs. It does solve labor issues such as cost, availability, and now the ability to operate with reduced threat of shutdown due to a COVID outbreak. Perhaps the cost of fuel can be offset somewhat in the future with solar input. It does appear as though farming is becoming more automated through the use of AI and GPS.

 

Now that would be good. Plus taking the place of all those chemical weedkillers, has got to be a good thing.
