Lightweight, Soft Exosuit Aims to Prevent Musculoskeletal Injury in Warfighters

Warrior Web
Harvard University’s Wyss Institute for Biologically Inspired Engineering is continuing development of a lightweight, soft exosuit for DARPA’s Warrior Web program, which is aimed at creating technologies that mitigate musculoskeletal injuries among warfighters while improving performance. The Wyss team is seeking to integrate component technologies developed in separate Warrior Web efforts into a prototype suit that offers expanded capabilities. DARPA plans to test the final suit in appropriate mission profiles under realistic loads to evaluate performance.    Article

Blood-cleansing “Artificial Spleen” Technology Could Increase Survival Odds for Future Sepsis Patients

Shield 

Sepsis—a life-threatening over-reaction by the immune system to infection—afflicts 18 million people a year worldwide and kills between 30 and 50 percent of them. Sepsis poses a significant threat to warfighters who suffer combat injuries that predispose them to infection. Antibiotics can kill sepsis-inducing microbes but their overuse is contributing to the threat of drug-resistant microbes and they don’t neutralize the toxins that some pathogens leave behind. Commercial dialysis equipment can remove toxins from the blood but is not built for routine use in theater. Article

SIMPLEX seeks to use mathematical models and tools to represent complex, diverse scientific data in a computable format to speed discovery, analysis and hypothesis generation. This diagram depicts the iterative discovery process that SIMPLEX aims to facilitate.

New Mathematical Tools Seen as Key to Maximizing Value of Scientific Data and Accelerating Discovery

SIMPLEX seeks to use mathematical models and tools to represent complex, diverse scientific data in a computable format to speed discovery, analysis and hypothesis generation. This diagram depicts the iterative discovery process that SIMPLEX aims to facilitate. 

The exponential growth of diverse science data represents an unprecedented opportunity to make substantial advances in complex science and engineering, such as discovery of novel materials or drugs. However, without tools to unify principles, results, models and other kinds of data into a single computational representation, it is difficult to relate data from any one scientific problem or area to the broader body of knowledge.

DARPA’s Electronic-Photonic Heterogeneous Integration (E-PHI) program has successfully integrated billions of light-emitting dots on silicon to create an efficient silicon-based laser. The breakthrough, achieved by researchers working on the program at the University of California, Santa Barbara (UCSB), will enable the production of inexpensive and robust microsystems that exceed the performance capabilities of current technologies.  Article

GXV-T Envisions Future Armored Ground Vehicles that Could Sprint, Dodge and Shield Their Way Out of Danger

GXVT 

One of the key goals of DARPA's Ground X-Vehicle Technology (GXV-T) program is improving the survivability of ground-based armored fighting vehicles by increasing vehicle agility. Vehicle agility involves the ability to autonomously avoid incoming threats, either by rapidly moving out of the way or reconfiguring the vehicle so incoming threats have a low probability of hitting and penetrating—all without injuring the occupants in the process. This concept video illustrates three of many potential approaches: active repositioning of armor, burst acceleration and suspensions that would enable the vehicle to dodge. Article

Wanted: Insights to Guide Creation of Robotic Satellite-Servicing Capabilities in Geostationary Earth Orbit

DARPA has issued a Request for Information (RFI) seeking technical and business insights to support the agency’s pursuit of technologies and industry partnerships that would enable robotic servicing missions in geostationary Earth orbit (GEO). The agency is considering the possibilities of integrating DARPA-developed space robotics technologies onto commercial spacecraft to create a jointly developed GEO robotic servicer. The commercially owned-and-operated servicer would work cooperatively with client satellites to support a variety of multi-year on-orbit missions, including inspection, correction of mechanical problems and orbit adjustment. DARPA seeks to create a capability that could both maximize the utility of current space infrastructure and lead to revolutionary future capabilities.  

An increasing number of expensive, mission-critical satellites are launched every year into geostationary Earth orbit (GEO), approximately 22,000 miles above the Earth. Unlike objects in low Earth orbit (LEO), such as the Hubble Space Telescope, satellites in GEO are essentially unreachable with current technology. As a result, these satellites are designed to operate without any upgrades or repairs for their entire lifespan—a methodology that demands increased size, complexity and cost. The ability to safely and cooperatively interact with satellites in GEO would immediately revolutionize military and commercial space operations alike, lowering satellite construction and deployment costs and improving satellite lifespan, resilience and reliability.
