Visits and Deliverables

Elias Tsigaridas, Thanos Kakargias, 
Ioannis Emiris, Sylvain Pion, David Daney.

13-20.10.04. David Daney and Sylvain Pion (Geometrica group) visited Athens. David Daney gave a seminar on Calibrating parallel robots. The collaboration included the following students of Univ. of Athens: Elias Tsigaridas, Nondas Fritzilas, Thanos Kakargias.

The main themes of collaboration were: calibration of parallel robots, calibration with additional distance contraints, robot kinematics under inexact distance constraints, over-constrained polynomial systems.
 

15-20.11.04. Ioannis Emiris visits COPRIN. Themes included calibration of parallel robots, calibration with additional distance contraints, applications to molecular structure. Collaboration also with Yves Papegay and Arnold Neumeier.

May '05. Elias Tsigaridas visits COPRIN. Themes included real solving in C++ and over-constrained polynomial systems in Maple.

3-13.9.05.  David Daney visited Athens. David Daney gave a seminar on Calibrating parallel robots. The collaboration included the PhD students, George Tzoumas and Elias Tsigaridas. The main themes of collaboration were: calibration with additional distance contraints for planar robots, over-constrained polynomial systems with resultants and/or optimization techniques.

12-15.9.05. David Daney, Elias Tsigaridas and George Tzoumas participated in the conference CASC, co-organized by Ioannis Emiris.

4-9.12.05. D. Daney and Y. Lebbah (Oran, Algeria) (talk) visited Athens and participated in the Workshop on "Parallel Robots, interval arithmetic and optimization" organized at the Dept. of Informatics. The Workshop was followed by discussions with engineers working in greek robotics companies.

Feb. 2006: I.Emiris visited INRIA Sophia-Antipolis, worked on calibration and wire robots.

Feb. 2006: Joint publication "Calibrating parallel robots: on the elimination of pose-dependent parameters", by D. Daney, I. Emiris, Y. Papegay, E. Tsigaridas, J-P. Merlet. In Proc. Europ. Conf. Mechanism Science (Eucomes), Innsbruck, Austria.

July 2006: Christos Syrseloudis visited INRIA for 10 days, worked on parallel robots, calibration and design; also interval analysis methods for these problems.
