This gives me Black Mirror-fueled nightmares... not least because those videos suggest that a Black Mirror scenario may not be that far off and what probably saves us for now is battery capacity.

What's the Black Mirror scenario?

General dystopian outcomes. After world powers harness robotic armies, revolts will no longer be possible and citizens will be permanently enslaved and must succumb to whatever oppressions are put on them.

there ought to be plenty of money in this for delivering explosive payloads... (Edit: although come to think of it, in the animal world, jump height is much more constrained by 9,81 m/s2 than by body size)

Artillery exists. Delivering explosive payloads is a solved problem. Detecting humans is a solved problem. The hard part is reliably distinguishing enemy solders from friendly soldiers or civilians.

It's possible to know where the humans are but be unable to destroy them with commonly available artillery payloads due to them being well dug in with overhead protection.

These could swarm in the back door.

Why is walking the salient technology that will enable this? Why not wheels, or treads, or flying?

Physics constrains jump height to be about a few meters regardless of size. The basic problem is that the total energy required scales with mass, but the total energy available also scales with mass. The two end up cancelling out and you get a maximum jump height that is independent of size. What really matters is the energy density of your storage medium, which is the same to an order of magnitude for any system bas…

With special designs you can build up energy over time and then release it all at once, to reach sporadic super jumps. Example:

(But for all but extreme designs I fully agree with you)

It walks into your room, discovers you, and moves in to make the kill, but for some reason the gun trained at an odd angle. You see it take two shots that veer across to the corner of the room before it hilariously enters some self-correcting routine, seems to rediscover you, and finally blows your head off.

You get a chuckle before you die

Oh, right. There is a Black Mirror episode in which dog-like AI robots are hunting down humans [1]

If you watch it then those research legged robots will look rather more sinister... or maybe it's just me. That episode really stuck with me.

As a reminder: CMU and its robotics program is intimately associated with the US Department of Defense, and although there are certainly civilian applications for this technology, one of the most likely short-term applications is improving legged drones for battlefield deployment (often, it should be said, in humanitarian roles, including search and rescue, or support roles, such as ammo, food, and water resupply, bu…

Glad to see our universities making progress in this important area of national security.

They already do, really, but this is just a method of locomotion. If they want to hunt, they can hunt even if they're drones, or have wheels.
