NASA is testing a portable surgery robot in an underwater testing environment. The test will involve a remote surgeon sewing a tear in a rubber tube and conducting a skill test used for student doctors. The delay time between the movement of the robot and the feedback to the surgeon will be about 1 second. The connection will travel via 'a commercial Internet connection' from Seattle to Key Largo, FL. Then by wireless connection to a bouy. The Raven portable medical robot is tethered to the bouy. There is no further description of the internet connection used in the article...ISDN? IP2 with standard of service protocol?
