"Tekno" family of robots made by the Manley Toy Quest company.
The manufacturer describes the Dinkie Robots:
The Tekno Dinkie robot walks along with turning its head amd moving its arms. Each robot has a unique personality. The Tekno Dinkie robot comes with artificial intellgence that allows it to speak two languages interact with other Dinkie robots.
There is also a dog that goes with the set, but I don't have it yet.
All of them but the baby bot can walk. Their LCD screen is very expressive, really cute!
They play games, communicate with all the other bots, they interact with the website, they speak their own language and are motion sensitive. Nice and complecated as a robot pet should be.
