Abstract
A sled assembly for an inspection robot includes a first portion having a first sensor mount at a first horizontal position, and a second offset portion having a second sensor mount at a second horizontal position. The first horizontal position and the second horizontal position are horizontally displaced by a selected horizontal distance. The first portion includes a first plurality of sensor mounts, and the first plurality of sensor mounts include the first sensor mount. Also, the first plurality of sensor mounts include a first horizontal distribution profile providing a horizontal displacement between adjacent ones of the first plurality of sensor mounts that is not greater than a selected inspection resolution.
