  • Over 80 technical papers in various areas of research interests

  • On-going research projects:

    •  Robot Drawing of Chinese Painting and Calligraphy: A drawing platform with 5 DOFs for the modeling, identification and validation of brush-pen techniques. GA-based stroke generation for duplication of given artwork. Rendition and creation of new art styles.

    • Fuzzy Reduction, Approximation and Identification: Singular value-based approach to generate fuzzy rules from given input/output samples. Membership functions characterized by the conditions of sum normalization, non-negativeness, and normality.

    • Grid Point design/SVD consolidation Approach: Computational-based design approach for nonlinear system via grid point sampling, design, and parametric consolidation. Overall stability proof via Lyapunov analysis.

    • Formation Maneuvering of Autonomous Controlled Units: Formation characteristics and control architecture for assembly of control units. Validation platform in development supports experimental studies of formation breakup and re-establishment via imposing interactive potential between units.
