What to know

aibo is a robot pet in the truest sense. It does not do chores or carry payloads; it recognizes faces, learns tricks, develops a personality over time and behaves like a puppy.

Sony relaunched aibo in Japan in 2018 and brought it to the US later that year at about $2,900. Some features depend on a Sony cloud plan, so check what is included in your region.

Good for

  • People who want a robot pet, not a gadget
  • Collectors

Watch out for

  • Some features need Sony's cloud service
  • Current US availability and price vary; check before buying
  • Japan-market units may be region-locked
