While the original 'Aibo' still had a robot head, the new generation (ERS-1000) looks more like a cute toy dog. There are still technical limitations due to the battery capacity: according to Sony, the robot dog's battery lasts around two hours. After that, 'Aibo' has to be plugged in for three hours. The robot dog weighs 2.2 kg, has two cameras, fast LTE data transmission and small OLED displays in its eyes to make them more expressive.
