Multispectral Infrared Tactile Sensors Detect Internal Delaminations in Composite Airframes

Inspecting complex composite airframes, carbon-fiber aerospace panels, and multi-layer structural welds for hidden subsurface defects, micro-cracks, and internal delaminations has traditionally required bulky, offline nondestructive testing equipment that cannot be easily integrated into automated robotic manufacturing workflows. Solving this inspection bottleneck, sensor architects have embedded advanced multispectral infrared tactile sensor arrays directly into the end-effectors and inspection probes of industrial maintenance humanoids. By combining localized thermal excitation with high-resolution short-wave infrared optical detection, the sensor array analyzes subsurface thermal dissipation rates in real time as the robot glides across composite surfaces, identifying hidden structural flaws and internal delaminations that remain completely invisible to standard optical cameras and surface touch sensors. During live testing inside aerospace manufacturing facilities, the multispectral inspection humanoids successfully mapped internal composite defects with high precision during active friction welding and assembly verification tasks. Quality assurance leads highlighted that bringing advanced subsurface thermal inspection directly to the robot's manipulation unit streamlines quality control workflows, ensuring absolute structural safety and reliability for critical aerospace components.
