Project of Students of the Faculty of Mechanical Engineering: From Robot to Machines for making Cocktails
The Bachelor students of Mechatronics their knowledge gained during studies, practically apply in the final year of studies through projects on several subjects every year. Projects are implemented in a team: they are defined by subject professors, and usually students propose what they would like to do.
That was the following projects in this academic year:
CNC plotter
CNC plotter is projected by a group of students chaired by Luka Radunovic and Vuk Boskovic. Plotter has three levels of freedom of movement to move the spindle by three axis. This type of CNC machine may be used for the production of technical drawings, automatic document signing, simulation of hand drawing, in modern art, and with less modification it may be used for engraving, cutting off the thinner material, etc.
This CNC plotter is projected and done on professional way, and students may offer it to the market.
The equipment for CNC plotter was purchased from the funds of the Faculty of Mechanical Engineering and through national scientific research project ‘’Montenegrin Wearable Robots-MWR’’, chaired by Milena Djukanovic, Assistant professor (FoEE). Marina Mijanovic Markus, PhD, and Rade Grujicic, MSc, from the Faculty of Mechanical Engineering are researchers on the project next to the Chairman. Vuk Boskovic and Luka Radunovic, students of Mechatronics are also involved in the project via project CNC plotter. Rade Grujicic, MSc, and Chairman of the MWR project proposed the project.
How CNC plotter works may be seen here ovdje.
Student Luka Radunovic plans to make CNC machine for cutting off the aluminum on master studies, which will be left in the laboratory of the Faculty of Mechanical Engineering and which will be used by future generations for their projects.
Vuk Boskovic wants to be actively involved in projecting of bolide for student competitions in Formula races (Formula Student).
Artificial hand model
The group of students who projected and made the artificial hand model was chaired by Mihailo Vujovic. Their task was to project and implement artificial hand and to invent and project the way of moving the hand fingers, electrical connecting the sensors, motors and microcontrollers and control in human artificial hand. Hand movements and only fist for now, is managed with the human hand with special glove with sensors, in the way that artificial hand copies the movements of the hand with the glove. Structural parts of the hand are printed at 3D printer from PLA materials. Key parts for management and operation of the hand are microcontroller Arduino UNO, 5 servomotors for fingers movement and 5 flexible sensors on each finger of the glove.
3D printer is used for the implementation of the project, supplied by means of national project MWR, while other equipment (motors, drivers, microcontrollers, sensors and other smaller equipment) supplied by the means of the Faculty of Mechanical Engineering. M. Mijanovic Markus, PhD, the professor on the subject Project 1, proposed the project. Mihailo Vujovic is involved in nacional project MWR with this project.
How artificial hand work may be seen here- ovdje.
Mihailo intends to activate wrists of fist, elbow and shoulder on master studies in the forthcoming period, that prototype will be improved with the use of quality materials and parts and to improve the hand management.
Machine for making cocktails
Jovica Jelovac, Nikola Sarancic and Ivan Tosic, the group of students, wanted to project and make machine for making cocktails, what they proposed to the subject professor. Machine has 4 bottles of drink with dozers and moving platform with glass, which moves under the dozer. The very interesting fact is that students did their best in order to make machine with minimal expenses: they used parts from old printers and computers, and bottle holders with dozers were only bought. Motors and other electronic parts, the Faculty has already had for the Laboratory for Mechatronics.
The slider from the old printer is used for moving the platform with glass, which is adjusted for the use in machines. The platform with glass moves steeper motor via a toothed belt from the old printer. Dozer valves opens servomotor with a lever that raises the shutter dozer. Arduino Mega microcontroller with drivers for stepper and servo motor is used for the motor management. The case of the old computer is used as the case of the device, which is, for the stability and better appearance of the device, reinforced with chipboards. Also, LED lighting is installed because of more effective appearance. Power supply from the old computer is used for the device power supply.
Machine for making cocktails may be further improved in commercial purposes.
How the device works, may be seen here- ovdje.
Mars Rover Model
Bojan Djerkovic together with Nikola Soc and other colleagues from the group, made a simplified model of Mars Rover which is operated by remote control. Rover has the so-called Rocker-Bogie hanging, which is especially interesting, because it allows rovers to overcome obstacles easily, for example-stairs. Students made the chassis of rover from tubes for plumbing. Other equipment is purchased by the funds of the Faculty of Mechanical Engineering. Direction of movement of rover is managed differentially, which means that wheels may not rotate, and turning of rover may be implemented by the speed change and the direction of rotation of left and right wheels.
How rover with Rocker-Bogie with hanging work may be seen here- ovdje.
Humanoid robot
Students Nikola Draganic, Velibor Bulatovic and Mirko Djokovic projected and made humanoid robot. This humanoid robot is interesting, because walking is implemented with simple mechanism. Robot has one DC motor, from which the moving is transmitted on ‘’legs’’ via three coupled gears. The management is implemented via microcontrollers Arduino UNO and drivers for motor. The whole motor is made from sheet metal.
Students implemented several projects such as the smart house model, the device for automatic on/off heating or cooling and others.
The Management of the Faculty of Mechanical Engineering always encourages and financial supports the student projects and their implementation, because the management and teachers consider that the practical work and application of acquired knowledge is very important for quality education of future engineers.
