Combat robots recognize soldiers by how they walk
Technology
Modern autonomous machines can tell friend from foe by analyzing the subtle rhythm of a soldier's stride through the mud of a battlefield.
On the front lines, robots are learning to identify humans not by their faces, but by the unique signature of their movement. Using gait-recognition software, these machines distinguish between the specific way a soldier crouches while carrying an M4 rifle versus the stance required for an AK-74. This biometric filtering has helped reduce friendly-fire incidents by 40% in high-stress environments.
