Unmanned underwater vehicles (UUVs) have inherent operational and tactical advantages such as stealth and surprise. UUV size, weight and volume are constrained by the handling, launch and recovery systems on their host platforms, however, and UUV range is limited by the amount of energy available for propulsion and the power required for a given underwater speed. Current state-of-the-art energy sources are limited by safety and certification requirements for host platforms.
Robots hold great promise for amplifying human effectiveness in Defense operations. Compared to human beings and animals, however, the mobility and manipulation capability of present day robots is poor. In addition, design and manufacturing of current robotic systems are time consuming, and fabrication costs remain high. If these limitations were overcome, robots could assist in the execution of military operations far more effectively across a far greater range of missions.
Based on current quantum mechanical models, the energy density of the quantum vacuum is predicted to be high. Recent advances in fabricating material nanostructures and cavities have fueled the study of vacuum fluctuation-driven phenomena, indicating that the energy density can be modified locally.
Partnering rescue personnel with robots to evaluate high-risk scenarios and environments can help increase the likelihood of successful search and recovery efforts while minimizing the threat to human teams. Small robotics systems could provide significant aide in these scenarios, but shrinking down these platforms requires significant advancement of the underlying technology.
Current UAVs provide valuable intelligence, surveillance and reconnaissance (ISR) coverage for troops deployed overseas. However, UAVs cannot stay airborne for extended periods of time before needing to be refueled or serviced. DARPA’s Vulture program seeks to develop critical enabling technologies for an airborne payload to remain on-station, uninterrupted for more than five years, performing ISR and communication missions over an area of interest.
