Abstract: A system includes an inspection robot having a number of payloads, a number of arms mounted to the payloads, and a number of sleds mounted to the arms, where the sleds comprise an upper portion coupled to a replaceable lower portion, the replaceable lower portion having a bottom surface shaped to accommodate an inspection surface; and an inspection sensor coupled to the upper portion of the one of the plurality of sleds such that the sensor is operationally couplable to the inspection surface.

Abstract: A system includes an inspection robot, comprising a plurality of wheels that engage an inspection surface; a plurality of sensors positioned to interrogate the inspection surface; and wherein the plurality of wheels each comprise a first magnetic hub coupled to a second magnetic hub, and wherein the plurality of wheels further define a channel between the magnetic hubs.

Abstract: A system includes an inspection robot having a number of payloads, a number of arms mounted to the payloads, and a number of sleds mounted to the arms. The system includes a number of sensors, each mounted to a corresponding sled, such that the sensor is operationally coupleable to an inspection surface in contact with a bottom surface of the corresponding sled. A couplant chamber is provided within at least two of the sleds, the couplant chamber between a transducer of a sensor and the inspection surface. The system includes a biasing member for each of the arms, where the biasing member provides a down force on the corresponding sled.
