i-Snake, a New Robotic Surgeon

Roland Piquepaille noted coverage of the iSnake Robotic Surgeon which is basically a super flexible robot that can travel through blood vessels and repair the heart. Of course the article isn't exactly clear on what happens if they gain control of the city's sewage system and take over.

Article short on details, title misleading.

I don't understand why they're calling this device a robot in the first place. It doesn't operate in even a semi-autonomous fashion, at least given the information found in the (very sparse) linked article. I fail to see how this device is groundbreaking; similar surgical techniques have been in use for years. If somebody has a better link, or at least one that doesn't sound like a fluffed-up ad, please help me out here.
