An unmanned aerial vehicle (UAV) configured to land, take off, and magnetically stop on a ferromagnetic cylindrical surface is provided. The drone includes a body and hinged magnetic legs configured to land and magnetically stop the drone on a cylindrical surface. Each magnetic leg has a fixed portion coupled to the body and a pivot portion pivotably coupled to the fixed portion at a pivot axis. The pivot portion includes a switchable magnet and a single articulated joint providing a single degree of freedom for the pivot portion about a pivot axis to passively place the pivot portion in an inward and tangential orientation in response to contact of the pivot portion with the cylindrical surface during landing, and passively maintaining an inward orientation of the pivot portion during takeoff.

    提供了一种被配置成在铁磁性圆柱形表面上降落、起飞和磁性停留的无人机(UAV)。该无人机包括主体和铰接磁性腿,该磁性腿被配置成使无人机在圆柱形表面上降落和磁性地停留。每个磁性腿具有耦接至主体的固定部分和在枢转轴线处可枢转地耦接至固定部分的枢转部分。枢转部分包括可切换磁体和单个铰接关节,该单个铰接关节为枢转部分提供围绕枢转轴线的单自由度,以响应于在降落期间枢转部分与圆柱形表面的接触而被动地使枢转部分处于向内并与圆柱形表面相切的取向,并且在起飞期间被动地保持枢转部分的向内取向。
