ROBOTSKA CELICA S SUBMIKROMETRSKO RESOLUCIJO
Gregor Škorc, 2011, doktorska disertacija

Opis: V okviru doktorske disertacije je predstavljen razvoj eksperimentalne robotske celice, ki je zmožna pozicioniranja s submikrometrsko natančnostjo. Robotska celica temelji na petih PiezoLEGS® motorjih, od katerih dva izmed njih formirata X/Y manipulator, ostali trije pa služijo kot podajalne mizice po Z osi. Konvencionalne izvedbe krmilnikov za vodenje PiezoLEGS® motorjev ne omogočajo avtomatske adaptacije parametrov gibanja motorja. Gibanje v visoki resoluciji botruje nizkim hitrostim, kar ob gibanju manipulatorja na daljše razdalje privede do velike potratnosti časa. Disertacija obravnavana adaptivno položajno vodenje robotske celice s konvencionalnem krmilnikom Trinamic TMC-090, ki je dodelan tako, da omogoča avtomatsko adaptacijo parametrov vodenja. Tri klasične tehnike položajnega vodenja so nadgrajene z adaptacijskim algoritmom in preizkušene v okviru testa odziva na stopnico in testa sledenja trajektoriji. Predstavljeni sistem robotske celice je zgrajen fleksibilno in omogoča integracijo različnih orodij. Kot praktični primer uporabe takega sistema je prikazana izvedba manipulacije z vakuumskim in piezoelektričnim prijemalom, ter mikroskopiranje z Akiyama sondo.

Position control with parameter adaptation for a nano-robotic cell
Gregor Škorc, Jure Čas, Simon Brezovnik, Riko Šafarič, 2011, izvirni znanstveni članek

Opis: This paper describes the development of a nano-assembly system, built up using linear piezo motors. The so-called nano-robotic cell is based on an X/Y manipulator, supported by three serving tables, movable within a Z axis, and aposition controlled using two different types of a bang-bang control methods. The presented application has been developed as a stand-alone application with the LabVIEW Real Time software package, a PCI-7356 servo controller card and a TMCM-090 stepper driver. Our experiments focused on two major problems present during the construction of nano-robotic assembly cells. The first one is a nonlinear characteristic of a linear piezo motor, which makes the use of classical control methods very limited. The second problem appears when a nano-robotic cell needs a bigger working space and at the same time, production demands that the manipulator moves more often over longer distances. In order to position in nano-resolution, the motors have to run at higher resolutions with smaller speeds. Therefore, long distance moves slow down the entire production process. Experiments on this system have shown that positioning within the nano-scale is possible, using a simple control method such as the bang-bang control method. Although positioning using this method is possible, certain limitations and weaknesses exists, making this simple method useless in nano-scale if higher speeds and longer move distances are needed. Certain changes in the basic control algorithm are proposed, which will ensure that the bangbang control method becomes useful within higher speeds and over longer distances. All recommendations are supported and backed- up by practical experimental results.

Interface between macro and nano worlds
Gregor Škorc, Riko Šafarič, David Lukman, Sirhiy Ivanovich Protsenko, Simon Zapusek, 2010, izvirni znanstveni članek

Opis: This paper describes the design of a nanorobotic application which includes: nanorobotic arm, Akiyama sensor system, a vacuum chamber, and an interface tools for the nanorobotic hardware developed using C++ and VRML languages in order to create a desktop virtual-reality environment which improves visualisation and prevents collision of the nanomanipulator hardware with the associated workspace. The presented experiment shows how the used man-machine interface could be used for communication between macro and micro/nano worlds.
