Understand the format first
Four common companion robot types
Appearance can be misleading. Start with where the robot operates, how it moves and who it is designed to support.
Desktop character
Tabletop robots focused on expression, touch, voice and entertainment.
- Examples
- Eilik, EMO
- Cost
- Low–medium
- Watch
- Limited mobility
Mobile robot pet
Wheeled or legged robots that travel through a room and react to their environment.
- Examples
- Loona, aibo
- Cost
- Medium–high
- Watch
- Stairs and maintenance
Portable companion
Small devices designed to travel, with necessarily limited battery, speaker and movement.
- Examples
- Eiliko, AIBI
- Cost
- Low–medium
- Watch
- Battery and size
Specialized support
Products designed around learning, routines or companionship for a particular audience.
- Examples
- Miko 3, ElliQ

- Fit and privacy
How to read this: format describes the main use—not quality. More movement or a higher price does not automatically make a robot better for a particular home.
