Sounds like it would be a fun experience!

I know this comment was made tongue-in-cheek, but I'd argue the use-case depends on where you live. There are many crime-ridden areas within the US that are hostile toward homeowner defense in case of a break-in. Additionally, these areas are often under the jurisdiction of understaffed or demotivated law enforcement agencies.

I'd prefer having a robot serve as first-line of defense for home invasions versus me confronting an armed burglar while half-awake in my underwear. Despite burglary alarm systems, response times are often laughably delinquent.

I live in an area where the median home price is 7 figures (it's mostly expensive land rather than opulent homes). My neighborhood averages at least 6 home invasions per year. These aren't performed by your average criminal - they operate in sophisticated groups that employ WIFI jammers to knock out security cameras before breaking in. This is a significant issue across other areas of the US.

That said, I'd prefer a robot with both defensive and home assistant capabilities :)
