IHMC’s Alex humanoid wins Army xTechHumanoid demonstration stage
IHMC’s Alex humanoid won the demonstration stage of the U.S. Army’s xTechHumanoid competition at Marine Corps Base Quantico in Virginia, according to IHMC. The institute and four other organizations now advance to structured evaluations, with an opportunity to secure an Army prototype evaluation contract in the final phase. More than 100 companies and institutes submitted proposals, and the Army selected 10 organizations to demonstrate their humanoid robots at Quantico.
IHMC attributes Alex’s result to hybrid autonomy, combining AI decision making with human operator control for complex missions. The Army structured the competition to assess both the capabilities and current limits of humanoid technology, with the eventual goal of handling physically demanding tasks and reducing soldiers’ exposure to dangerous situations. Robert Griffin, the senior research scientist leading IHMC’s robotics group, described unfamiliar buildings as a target operating environment: Alex is being designed to enter through doors or windows, negotiate obstacles and move furniture during searches for improvised explosive devices. These are development goals, rather than a list of tasks IHMC says Alex completed at Quantico. “We are not designing Alex to make active combat decisions or to do things like exercising force,” Griffin said.
The competition result follows an earlier demonstration for the Office of Naval Research, which funds Alex’s development through a multiyear, multimillion dollar project. According to IHMC, that demonstration featured Alex walking untethered over gravel and along slippery and uneven surfaces. Those locomotion tests address a practical part of the proposed missions: reaching and traversing difficult terrain without a tether. The next structured evaluation phase will give IHMC another opportunity to demonstrate how Alex handles complex environments and the high degree of uncertainty Griffin identifies as a central design challenge.
