Are there any Boston Dynamic robots currently in use? Specifically the biped ones, but I'm also interested in the quadrupeds, which they seemed to be pushing for military/search and rescue/packhorse uses.
They use flying drones all the time, you can see them flying around in the Starbase live streams. I can't think of anything off the top of my head that a flying drone can't do but spot would be able to do at Starbase. Unless Spot can crawl into a pipe or tank maybe.
Anything that involves adding weight to the robot (e.g. carrying something from point A to point B) seems like something more suited for Spot than a camera drone.
The quadrupeds saw use in Singapore during COVID (2020) to remind people about social distancing, today (2024) they're being used in car manfacture plants to "fetch" for other fixed robots.
The IDF has the quadrupeds and there has been some videos of them being deployed. Can't search Twitter for you, but if you have an account there you'll likely be able to find some examples.
