Anki has announced what they have referred to as "an older brother" to Cozmo. His name is Vector and based on my early impressions of him, he is going to be great!
Vector, unlike little brother Cozmo, has that "always-on" functionality and will be able to zip around on his own. No precious phone WiFi connections need to be sacrificed. Vector also has upgraded internals making him more powerful than before, which should also lead to improved battery life.
