Here's everything Amazon just announced: A home robot named Astro, a fitness band and more

Astro is equipped with Amazon's Alexa voice assistant. It can set and deliver reminders, serve up entertainment such as TV shows or podcasts and control smart home devices, among other tasks. The robot also responds to commands; so if users say, "Astro, beatbox," the robot will make musical noises.

The robot also has security and safety features. Through an integration with Amazon's smart home security subsidiary Ring, Astro is capable of autonomously patrolling a user's home while they're away. It can flag potential intruders and listen for things such as broken glass or smoke alarms via a feature called Alexa Guard.

For those worried about privacy, Amazon said Astro's camera, microphone and motion sensors can be switched off by pressing a button. Users can also designate "out of bounds zones," or certain rooms that are off limits to the robot.

Starting today, Astro costs $999.99 and is available via invitation only. Amazon didn't reveal a release date for the robot, but it said it will begin granting invitations later this year.
