  "abstract": "Extension tools and methods of inserting extension tools within components are provided. For example, an extension tool has a proximal end and a distal end and comprises a plurality of sequentially arranged links moveable relative to one another and a support member defining the distal end and including a first wheel disposed at the distal end and a second wheel spaced apart from the first wheel. The extension tool may comprises a plurality of windows defined in the plurality of sequentially arranged links. The windows are defined periodically along the plurality of sequentially arranged links such that a periodicity of the widows corresponds to a periodicity of a plurality of features of the component.",
