I figured you might have run across FarmDroid before, they've had a "complete" demo video for the model tested here up for three years or so.
It appears to be a 'dumb' (but accurate) weeding and seeding solar powered battery backed "runs all day and much of the night" platform.
I say dumb as the major feature seems to be highly accurate (sub inch) positioning ( I'm guessing on site grounded in GPS differential base station as an error broadcast | local reference ) with a taunt bright red bit of heavy string sprung out around the four corners .. ie no vision processing and a simple "detect tree or human" stop moving trip wire.
It'll seed, remember seed positions and "weed" (disturb soil) about the remembered seed position .. but I'm guessing it'll weed out planted seeds if there's an origin or axis positioning error in re-calibration.
Still, it's being used in several countries - the 58 minute weekly Landline program devotes 10 or 12 minutes to it and the name is given of the Queensland(?) Ag. Dept. officer who's trialing it out (along with other systems).
That'd be the main point of interest for you if you ever get to wanting to officially test your rig in Australia.
Landline is free to view in Australia - it's just yt-dlp.exe that-url-I-gave-above with an AU proxy .. I can always drop it or just the relevant transcript if want either the .MKV or .SRT
And “aim it at the moon” hah yeah. The Dish looks cool! I hadn’t heard of it I will give it a watch.
