3. Micro robotic systems, their integration and control

As we have seen, the requirements of the microworld call for the replacement of actuators used in traditional robotics by microactuators, and the replacement of robot mechanisms by deformable structures. However, carrying out robotic tasks on a micrometric scale comes up against major difficulties linked to the realization of small-scale functional robots (and, more generally, of complete microrobotic cells), to the analysis and consideration of interactions on a micrometric scale and, finally, to the difficulty of accessing the microworld. All these factors have important consequences in terms of integration and development of microrobotic device control. These points and difficulties will be addressed in the remainder of this section.
