Inspection robot having vertically distributed payloads with horizontally distributed sensor sleds

A system, comprising:

• an inspection robot, and a plurality of sleds mounted to the inspection robot;
• 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 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 each couplant chamber comprises a cone, the cone comprising a cone tip portion at an inspection surface end of the cone, and a sensor mounting end opposite the cone tip portion, and wherein the cone tip portion defines a couplant exit opening;
• a couplant entry for each couplant chamber, wherein the couplant entry is positioned between the cone tip portion and the sensor mounting end, and wherein the couplant entry is positioned at a vertically upper side of the cone in an intended orientation of the inspection robot on the inspection surface;
• wherein the plurality of sleds are horizontally distributed across a payload, and wherein the payload is mounted to the inspection robot;
• and
• further comprising a plurality of payloads each having a plurality of the sleds horizontally distributed thereacross, and wherein the plurality of payloads are vertically distributed.
