Definitions

  • the present invention relates to connecting structure between building blocks according to the preamble of claim 1 and a building block according to the preamble of claim 15 .
  • Building blocks are known for example as passive structural elements/building blocks or also as modules (actuators) of automation systems where the building blocks advantageously form robots.
  • DE 10 2010 062 217 A1 describes a kit system with several modules wherein each module is connected with any other module through a continuous electrical and information connection. This coupling is provided by a stereo jack connection. Additionally the modules are fixated relative to one another in three dimensions by a magnet connection which includes four magnet pairs which are arranged at a 90° angular offset from one another so that the square base surfaces of the modules can be arranged in four different orientations relative to one another. In the 45° positions that are arranged there between the modules can be disengaged from one another easily.
  • the magnetic connection supports a certain amount of load in a direction of the magnetic effect, however it is very susceptible to shear forces or forces perpendicular to the magnetic which is also prone to damage the coupling. Furthermore magnetic forces cannot be increased indefinitely since electromagnets typically cannot be used or an increase of the magnetic forces makes it difficult to disengage the modules from each other.
  • WO 99/91261 A1 discloses a reconfigurable modular robot connection.
  • the different modules are connected with one another through corresponding flange elements which are clamped together with a circumferential brace. This is not a one joint connection of the two modules but a two joint connection since additional connectors in this case the brace are required.
