Medical bugbot from CMU NanoRobotics Lab

It doesn’t quite meet the “under 100 nm” requirement, but the internal parts must: The Pittsburgh Post-Gazette reports that a robot combined with a swallowable camera could give doctors a better look inside the small intestine. This medical robot, dubbed ‘bugbot,’ is being developed at Carnegie Mellon University (CMU) in its NanoRobotics Lab. It will measure less than 800 nanometers in diameter and will transmit thousands of images during its trip inside yourself with its embedded camera. With the six legs attached to the microrobot, CMU researchers want to give more control to camera operators, such as coming back to a suspected lesion. This robot should be ready for human inspection within 2 to 3 years and opens the way for future nanorobots. This overview contains more details about this project. (Credit Roland Piquepaille)
