Amazon's new robot called Astro is designed to track the behavior of everyone in your home to help it perform its surveillance and helper duties, according to leaked internal development documents and video recordings of Astro software development meetings obtained by Motherboard. The system's person recognition system is heavily flawed, according to two sources who worked on the project.

The documents, which largely use Astro's internal codename "Vesta" for the device, give extensive insight into the robot's design, Amazon's philosophy, how the device tracks customer behavior as well as flow charts of how it determines who a "stranger" is and whether it should take any sort of "investigation activity" against them.
