Amazon launches its first wall-mounted speaker at unveiling event

Tech giant Amazon unveiled several new products on Tuesday, including a $1,500 autonomous robot that can monitor a person's home for intruders. Undoubtedly the cutest product making an appearance on Tuesday was its Alexa-powered robot, called Astro – although it's available to purchase by invite for people in the U.S., meaning interested customers have to sign up to have a chance to buy. The $1,450 robot uses intelligent motion to check-in on your home while you're away and give alerts about any disturbances. It can move autonomously around your home, navigate to check in on specific areas, show a live view of rooms through the Astro app, or send alerts if it detects an unrecognized person. Astro uses its digital eyes on its rotating screen, body movements, and expressive tones to communicate, according to Amazon.
