Amazon is launching Astro, its first household robot, powered by its Alexa smart home technology.
The company said it can be remote-controlled when not at home, to check on pets, people, or home security.
It can also patrol a home automatically and send owners a notification if it detects something unusual.
Amazon said it was more than “Alexa with wheels” and had been programmed with a range of movements and expressions to give it personality.
