Telepresence robots will become more popular with time, as will robot vacuum cleaners. iRobot makes both. The Ava 500 has:
- Mapping and autonomous navigation – just tell it where to go, no need to steer it
- Obstacle detection and avoidance
- Videoconferencing via an iPhone or iPad
- HD video with encryption
- 6 hour battery
- Auto-docking
While similar products are basically an iPad on a stick with wheels, the screen on the Ava 500 is 21.5 inches.
