Super interesting as always Paul!
In my field we have been using drones for a few years but a lot of the laws/rules in the US make it more difficult than in Mexico for example.
There are some pretty cool technologies, drones that check fence lines for breaks etc., k-9 robots with all kinds of sensors (what the army is doing with those is nightmare inducing...). This is from 2023 at a trade show.
I have seen some tethered systems as well, I think I have only every seen one put into practice where the drone was tethered to a Polaris Ranger.
All cool stuff and I anticipate the innovations will continue at a rapid pace.
