Shielding Inspection Robot
Periodic Robotic Visual + NDE Inspection
The shielding inspection robot is a 10 kg mobile non-destructive evaluation platform that surveys high-density and borated polyethylene radiation shielding every six months to detect micrometeoroid and orbital debris damage, surface defects, and internal voids. Drawing 20 watts of power, the unit couples a high-resolution camera with an ultrasonic probe, using machine learning defect classification to flag anomalies and trigger panel replacements over a 15-year operational lifetime. Surviving the harsh lunar radiation environment across these multi-year verification campaigns requires radiation-tolerant electronics capable of maintaining a 20,000-hour mean time between failures.
Periodic visual + ultrasonic inspection robot verifying HDPE/BPE panel integrity, detecting MMOD damage, and triggering replacement.
Purpose
Periodic visual + ultrasonic inspection robot verifying HDPE/BPE panel integrity, detecting MMOD damage, and triggering replacement.
Context
Child of L2-RAD-POLY within the Lunar Ark system
Principles
- ▸High-res camera scans panel surfaces
- ▸Ultrasonic probe detects internal voids/damage
- ▸ML defect classification with anomaly flagging
