B. Sc. degree: Graduated in July, 1978 at Department for Automation at the Faculty for Mechanical Engineering from the University of Belgrade.  Supervisor: Prof. Dr. Ljubomir Grujić.

M. Sc. thesis: Post-graduate studies inscribed in the 1979, and passed all examinations with: average mark 9.67. Master of Sciences degree is obtained on 9th of March, 1998. Master Paper title: «An Analysis of Dynamic Accuracy of Manipulation Robots» at the Faculty for Electrical Engineering of the University of Belgrade.  Supervisor: academician Miomir Vukobratović.

Ph. D. thesis: She is now working towards Ph.D. degree (in final stage) at the Faculty for Electrical Engineering of the University of Belgrade, under title: »Contribution to Modeling of Flexibility of Active Mechanisms with Special Emphasis on Humanoid Robots«. Supervisor: Prof. Dr. Veljko Potkonjak.

Professional experience: On the 1st of April 1979 started working in the Institute «Mihajlo Pupin», 11060 Belgrade, Volgina 15, and work there until now. Up to 1991 major concern engineering assignments and projects devoted my work to the «Center for Pneumatics», IMP, managed by M Sc Vladimir Kokotović. Worked on: projecting, manufacturing, mounting and starting: control regulation electro-pneumatic systems for drinking water purification for Chemical, Food and Pharmaceutical Industries, «pneumatic forwarding system» and development of components for above pneumatic forwarding equipment. She was realized series of Technical Solutions and participated in  projects of relevance in this area.

The tasks in the field of Robotics are fulfilling within the last 15 years.

In the field of scientific research she is pursue:

1)      Modeling and analisis of robot sistems with elastic link (two modes):

·                    kinematics

-         new definition of joints,

-         planing of reference trajectory with or without elastic deformation.

·                    dinamics

-         the comparative analysis of the EBA(“Euler-Bernoulli Approach”) and LMA(“Lumped-Mass Approach”,

-              structure of the matrix of stiffness,

-              characteristic of  damping,

-              structure of Naviers equations,

-              the mathematical model of the motor,

-              a general form of a transversal flexible deformation,

-              the form of the elastic line.  

In modeling and analisis simultaneously presented and elasticity of the gear as well as the environment force dynamics.

2)      Modeling and analisis of motion biped on mobile or immobile platform with or without elasticity elements:

·        kinematics

-         a joint is defined in in a new way,

-         planing of reference trajectory with or without the property of 

1) coupling, and (or)

2) elasticity.

·        Dinamics:

The matematikal model defined in general form and  describes the motion dynamics of any biped-platform konfiguration that contains elasticity elements.

·        The software FLEXI:

The software FLEXI is developed and can be used for the synthesis and analysis of complex elastic robotic systems of biped-platform type, and also can be expanded from various aspects, according to the user's needs.

The algorithm defined generates mathematical model of a complex humanoid robotic system that walks on an immobile/mobile platform. It holds for an arbitrary number of DOF of the chosen biped and an arbitrary number of DOF of the platform. It was applied on a 25-DOF robot walking on a 3-DOF platform. The model equations change their structure depending on the nature of particular joints. The task of modeling is solved as a program, so that the user should only select the type of joints and, normally, all the system parameters, and the software package will generate a model which offers the possibility of analyzing its dynamic behavior.
