They have walking robots, but those are expensive and need to be connected to a cable as far as I've seen. I bet you fewer people would mess with em though if you gave em arms. I don't suppose they'd give them the ability to fight back, but if they did that springing up from laying down thing and ran off, I imagine people would leave them alone out of fear. It would still mess you up if it like landed on you.

Using a tether during testing is just good sense - even if you don't need it, you don't know you don't need it until you've done the test.
Seems like to go a useful delivery distance, they'd need huge batteries, but IDK.
