Product/3D Designer

I am a product designer and i recently got my degree in mechanical engineering. I am experienced CAD Designer and I work in programs like Solidworks and CATIA on daily basis. I am also familiar in working with Autocad. Throughout collage i worked as a product designer in research and development department in a company that produces large scale printers where i designed customized parts on costumers demands. I am ready and glad to work with you and make all your ideas and projects come alive.

Portfolio

The point of this project was to make a mechanism that can kick the ball outside the glass after 5 seconds without touching the glass.
Also any electronic devices for timers were forbidden The mechanism consists of three springs that are placed in cylinders that are connected to a upper plate with a hook seen in pictures. The windup mechanism consists of wind-up spring inside the housing (orange color) connected to a shaft that can be winded with hand. When the mechanism is winded, the shaft moves the green plate which unhooks the hooks and the ball is catapulted in the air.

Catapult

This project was a part of my Master's thesis where on of the jobs was to design a new Phantom model for use in measuring precision and accuracy of robotic neurosurgery stereotactic systems. Phantom design was customized for a robotic system used in my collage and as a part of the project a simulation was done to detect any possible collision in the process between robot and the phantom. I also drawn the Mayfield clamp model myself for the purpose of simulation.

Phantom for robot neurosurgery

In this project i drew a simplified representation of a satellite with a robotic arm with 2 DOF. Kinematics of the arm was simulated in program CATIA and it was moving according to the predefined function.

Satelite design

In this project a robot is designed with a end effector that could carry 5 kg (11 lb). For that purpose the end-effector was analyzed using FEM for the double maximum load of 10 kg. Also complete kinematics of robot was analyzed in CAD program CATIA.
Assembly consist of 16 parts.

A new phantom design for neurosurgical robotics

5th Croatian Computer Vision Workshop (CCVW)

In this paper we propose a novel phantom design for measuring application accuracy of neurosurgical robotic systems and stereotactic frames. We develop a novel phantom (T-Phantom) which enables simultaneous localization of translational displacements in entry and target points.

Tool condition monitoring in stone drilling with artificial neural network

International Conference on Mechanical Manufacturing and Control

This paper explores the possibility of tool wear classification in stone drilling. Wear model is based on Radial Basis Function Neural Network which links tool wear features extracted from motor drive current signals and acoustic emission signals with two wear levels – sharp and worn drill. The results indicate tool wear monitoring capacity of the proposed model in stone drilling, and its potential for simple and cost-effective integration with CNC machine tools.
