Al writes "Technology Review has an article about a snake-like robotic arm that could soon be used to treat injured soldiers as they lie on the battlefield. Developed by researchers at Carnegie Mellon University, the snakebot attaches to a stretcher and is controlled remotely using a joystick, allowing a doctor to assess a soldier's injuries as the bullets fly by. In future, the robotic arm will be fitted with sensors allowing it to measure vital signs and probe for internal bleeding. Here's a brief video of a prototype arm in action. The arm will become part of the US military's high-tech stretcher, called the Life Support for Trauma and Transport system. This is essentially a portable intensive-care unit, with a ventilator, defibrillator, and other physiological monitors, and it's currently being used in areas of Iraq and Afghanistan."
