Inspection robot with couplant chamber disposed within sled for acoustic coupling

A system, comprising:

• an inspection robot comprising a plurality of payloads;
• a plurality of arms, wherein each of the plurality of arms is pivotally mounted to one of the plurality of payloads;
• a plurality of sleds, wherein each sled is mounted to one of the plurality of arms;
• a plurality of sensors, wherein each sensor is mounted to a corresponding one of the sleds such that the sensor is operationally couplable to an inspection surface in contact with a bottom surface of the corresponding one of the sleds;
• a couplant chamber disposed within each of at least two of the plurality of sleds, each couplant chamber interposed between a transducer of the sensor mounted to the sled and the inspection surface;
• wherein the bottom surface of the corresponding one of the sleds is contoured in response to a shape of the inspection surface;
• and
• wherein the inspection surface comprises an outer wall having a convex shape, and
• wherein the bottom surface of the corresponding one of the sleds comprises a concave shape;
• and
• a biasing member coupled to each one of the plurality of arms, and wherein the biasing member provides a biasing force to corresponding one of the plurality of sleds, wherein the biasing force is directed toward the inspection surface.
