The first household robot, Astro, is being launched by Amazon. The home robot can be remotely controlled to check on pets, people, or home security, according to the company.

It can also automatically patrol a home and notify owners if it detects strange activity.

On its part, Amazon claimed it was more than just "Alexa on wheels," and that it had been programmed with a variety of movements and expressions to give it personality.

The compact robot also has an extendable "periscope" camera that pops out of its "head." The company demonstrated how to use it to check if a gas stove had been left on after leaving the house.

Chief Analyst at CCS Insight Ben Wood said "Astro is a bold move by Amazon, but a logical step given its expertise in robots and desire to become more integrated into consumers' daily lives.”

 Amazon says the robot will be available later this year, but only in the United States. Its price will rise to $1,449.99 after the initial, limited run, according to the company.
