At the IPAS Conference in 2008, we described in our presentation the idea of a construction kit for micro assembly based on a standardised interface for automatic exchange of (those times mainly) different grippers. In the meantime the construction kit has been developed further and completed purposively. So now automation of a wide range of tasks in the field of micro technology is carried out. At the actual state, the kit is including a miniature modular robot arm, two changing systems, various grippers, suitable storage racks, and additional tools such as cameras and dispensing tips. However the kit is open for everybody to adapt further elements and indeed this is done.
