Programmable micro-robot and assembly of such micro-robots forming a modular three-dimensional structure

A method for the manufacture of a micro-robot according to claim 1, said micro-robot being intended to form part of a programmable ensemble of micro-robots forming a three-dimensional structure with modulable geometry comprising the steps consisting of:

• electrically connecting a control unit to a flat flexible strip (3) comprising a set of reversible fastening devices (4), called RFDs, each comprising at least one pair of electrodes (12), enclosing the control unit and a part of the flexible strip adjacent to the control unit in a polymer layer in order to immobilize the control unit on the flexible strip, sealing two hemispheres of a polyhedral casing (2) inside which the control unit is housed;
• the flat flexible strip passing, by means of an opening, through the polyhedral casing, such that a portion of the flat flexible strip extends outside the polyhedral casing, and folding and immobilizing the portion of the flat flexible strip extending outside the polyhedral casing such that it hugs the shape of the polyhedral casing and extends over a part of an outer surface of the polyhedral casing.
