Overview


The aRC NDTest-R applies time-tested nondestructive testing methods with an innovative robotics platform. It can evaluate cavity walls and structural exteriors to identify issues before they become lethal problems.


Thorough inspections are slow, risky, and expensive using traditional methods. Our NDTest-R can safely and precisely apply large sensors across entire facades at a reasonable cost.

Note: a safety line with automatic brakes is used in all systems. We do not use any permanent anchors. We do not require a sidewalk shed.
