The Department of Defense (DOD) anticipates the realization of biomimetic bird and two-inch, insect-sized systems within the 2015–47 period. Although robot systems of one millimeter or smaller are not explicitly specified in current DOD and Air Force technology road maps, the technological aims towards this size can be clearly inferred from official documents. This research assesses the likelihood of, and barriers to, the realization of true microrobots and nanorobots (defined as submillimeter-sized robots of micro-meter and nanometer proportions, respectively) that can perform in military applications by 2035. This research finds that the realization of true microrobots for military applications by 2035 is unlikely, except for a single case of microrobots....
