Four years after the Aibo puppy was discontinued, some CAT scans and X-rays have emerged showing two of the models' inner parts. The CT scans don't appear to show any abnormalities, but then I'm no doctor. Or roboticist.
The Mechatronics Lab at the Mie University in Japan subjected the ERS-110 and ERS-210 models under radiography to get a better understanding of how Sony created them. There's a joke in there somewhere about a dog and a CAT scan, but I won't stoop so low. [Mie University via PlasticPals]
