The Defense Advanced Research Projects Agency (DARPA) is exploring a new robotic concept that navigates the human body to locate wounds and apply lifesaving treatment, giving injured frontline troops a better chance to survive until they reach a hospital.
Called Medics Autonomously Stopping Hemorrhage (MASH), the system relies on artificial intelligence to guide advanced sensors to a wound and autonomously apply clotting and healing materials.
In a practical application, medical crews would make a small incision in a soldier’s torso, allowing MASH to deploy its robotic components to temporarily stitch critical injuries.
DARPA said the concept is not about creating entirely new robots. Instead, it focuses on upgrading existing, combat-proven medical tools with smarter tech and autonomous capabilities.
“What we’re doing is we’re trying to make the robots that exist smart enough, with perhaps new sensors, to find and stop the bleeding,” DARPA Biological Technologies Office Program Manager Lt. Col. Adam Willis told SIGNAL Media.
“We’re very open, and people are coming to us with their ideas, and so that is what we’re trying to get done.”
A Three-Year Roadmap
MASH is planned in two phases over three years.
Phase 1, starting in summer 2026, will focus on technical development, including improving wound-localization and artificial clot formation.
By the end of 24 months, researchers expect MASH to autonomously identify active bleeding and locate wounds on soldiers.
Phase 2 will optimize the system and prepare it for potential battlefield deployment within 12 months.
“They have to bring it all together to find the bleed, and then position their robot in the right spot, and then stop the bleed, all with one device and one capability,” Willis stated.
