Apparatus and methods for providing a retractable mast

摘要

Apparatus and methods for raising a retractable mast comprise engaging at least three flat flexible strips such that each strip forms a side of a mast. Each strip comprises a set of tabs and slots disposed along opposite edges of the strips. The housing may further comprise a feed mechanism operable to interlock the at least three lengths of flexible strips by drawing the strips together causing each tab of each strip to engage with a slot of an adjacent flexible strip. In addition, the apparatus may comprise a controller module operable to control extending and retracting the mast. The apparatus may be incorporated in a robotic device operable to travel in at least a horizontal plane and extend the retractable mast.
