Laboratory for automatics, hydraulics, electric engineering and robotics

Division for automatics

Within the Division for automatics, the major part of laboratory exercises from the Elements of automatic control, Automatic control systems, Digital control and Design of components and systems for automatic control is done. All teaching activities are coupled with modest possibilities regarding the currently available equipment. At the moment, the following equipment is available at the Division for automatics: 

  • temperature PID regulator,
  • two biphasic step motors,
  • PC controlled controller for step motors,
  • PLC OMRON Micro 8 with 8DI/8DO/8AI,
  • controller Simatic S7-200. 

With this modest means, several exercises are developed, like: 

  • traffic-lights for traffic regulation at crossings,
  • model of the elevator,
  • model of the temperature chamber, etc. 

Most of the existing exercises are now used for educational purposes. Exercises within the Division for automatics are held by Milan Matijevic, Ph.D., associate professor. 

Division for hydraulics

Installation for measuring of hydro-mechanical quantities is situated at the Division for hydraulics.

Mentioned installation serves for experimental determination of coefficients of friction resistance with possibility for calibration of flow sensor with variable pressure drop, as well as for determination of local resistance coefficients. A physical nature of hydro-mechanical events and mechanical way of measuring parameters of these events may be demonstrated on the installation.


From the Division for hydraulics 

Basic elements of the installation are: centrifugal pump with electric motor drive, water reservoir, measuring reservoir, Venturi water gauge, orifice, air gauge table and pipeline. 

Installation is carried out in such a way that it is, first of all, used for educational activities. Namely, students of the 6th semester conduct the following laboratory exercises within the subject Fluid mechanics: 

  • determination of orifice characteristics, 
  • determination of friction resistance coefficient and 
  • determination of valve resistance coefficient. 

It is noticed that the installation is so designed that the other resistance coefficients may be determined also: 

  • determination of Venturi water gauge characteristic,
  • pipe bend resistance coefficient,
  • determination of resistance coefficient due to sudden dilatation,
  • demonstration of Borda's theorem and similar.

The basic goal of conduction of laboratory exercises is to give students an overview on numerical values of some hydro-mechanical quantities.

Laboratory exercises at the division for hydraulics are given by Slobodan Savic, Ph.D., assistant professor. 

Division for electrical engineering

Division for electrical engineering is exclusively used in teaching, in conduction of laboratory exercises from the following subjects: Electric engineering with electronics, Theory and technique of measurement, Mechatronics of motor vehicles and motors, Architecture of computer systems and Components of systems for automatic control II. The Laboratory has necessary equipment for conduction of exercises planned in syllabus of mentioned subjects. Jasna Radulovic, Ph.D., associate professor and Dragan Taranovic, M.Sc, senior teaching assistant perform laboratory exercises from the mentioned subjects. 


From the Division for electric engineering and Machine dynamics and robotics

The aim of the laboratory exercises is to meet the practical application of theoretical assumptions of some problems, acquiring experience in measuring and measuring accuracy. Firstly, the students independently connect the electrical schemes and, then, conduct the measurements under the constant supervision of the TA or laboratory  technician. 

Division for machine dynamics and robotics

Laboratory exercises from the Dynamics of machines and mechanisms, Industrial robotics and, partly, from Elements of automatic control, are done at the Division for machine dynamics and robotics. Within the exercises from Dynamics of Machines and mechanisms, inertial moment of the crankshaft is experimentally determined and a rotor is balanced. Balancing of disc shaped structures and sub-structures is done on LOS SAE-40 machine at one correction plane. A machine for balancing in two correction planes is situated at the Laboratory. Dynamic balancing of rotors in their own bearings is realized with measuring device SCHENK-FEDERN-WPI with polar screen, inductive sensors and contactless photo-sensors for angular positions. Rotor speed is measured by stroboscope. Additionally, the Laboratory has air compressor and three degrees of freedom manipulator for conducting the laboratory exercises in Industrial robotics. A couple of selsynes are used for teletransmission of angle values. Laboratory exercises from mentioned subjects are conducted by Vesna Rankovic, Ph.D., assistant professor.
