So you need to find a Formular regarding speed, energy and weight to lift in correlation to the overall weight and tire size. I'm curious when you will do those tests what the outcome is. At least when I look at it it feels that the energy limit and tire size might be a problem but of course this depends highly on the size.of the field. How much energy do you currently use when moving with things? Or while doing things? My assumption when weeding is that you drag something heavy around or do it with laser. Water I would not use dripping due to micro plastics and cost. I would also fertilize to a certain degree. Even organic has to fertilize. |

For weeding, the robot is heavy enough that if you were using a drag tool you wouldn't need extra weight. We might use a robot arm for weeding, not sure. However one of the tricks in regenerative organic is to prepare your soil in such a way as to avoid the need for much weeding during the crop growth cycle.
When I say "fertilizer is not used" I mean industrially-derived chemical fertilizer is not used. We would still need to spread compost and manure, which can be heavy! That would be one of the more energy intensive tasks. Who knows, maybe we will find we need a battery for that task. This would be easy to add. I think many tasks will not require a battery.
It sounds like you're interested in the farming process. Here is a quick overview of regenerative organic farming systems: https://www.youtube.com/watch?v=Ct3CL22RpTg
And this is a really nice detailed lecture series on a regenerative organic farming system: https://www.youtube.com/playlist?list=PLCeA6DzL9P4uRadXW0_hj...
In the second link, they use a two wheeled walk behind tractor that is I think 18 horsepower. We will have 1 to 1.5 horsepower effectively, so we will have to re-think some of the tools, but you can see how moving slower with no driver could get us in the ballpark.
Remember, farming can be accomplished by a single human with basic hand tools, and our robot has more power available to it than a single human can output continuously. Of course, humans are a lot smarter which certainly helps, but you can begin to see my reasoning for why I believe our approach is reasonable.
Also watering is usually done with impact sprinklers:
