Amazon has just launched a new home/companion robot that can follow you around the house thanks to it being on wheels. The Amazon Astro will map out your floor plan and do things like following voice commands, help you or your family stay in touch with others via voice calls, and even serve as an aid for eldercare.

With its computer vision, it can also check on your home while you're away. It won't be able to play with your pets just yet, but it has a dedicated periscope cam that pops up from its head to check things out. Think of it as a roving security bot.
