Device for performing at least one task on a structure to be worked on, said device comprising a telescopic presser element

A method comprising:

• performing at least one task on a structure to be worked on by using a device comprising:
• a frame;
• a fastener for fastening said frame to a motor-driven handler capable of moving said device at least partly in space relative to a structure to be worked on;
• a positioning/securing element for positioning and/or securing said frame to said structure to be worked on;
• a spindle rotatably or translationally drivable along a same axis in order to perform said at least one task;
• a presser element, coaxial with said spindle, capable of exerting a compressive force against the surface of said structure to be worked on when said device is secured to said structure by said fastener;
• said presser element comprising a first and a second element connected by a ball-and-socket joint, said second element comprising a free end capable of contacting said surface and said first element being translationally movable along the axis of said spindle in such a way that the second element is oriented orthogonally to said surface when compressed against said surface;
• and
• wherein performing the task comprises translationally moving said first element along the axis of said spindle in such a way that the second element is oriented orthogonally to said surface when compressed against said surface.
