2017 (Open Source Project)

Rover (APP4MC-rover) is an open-source mobile robot that is designed to test the outcomes of APP4MC and APPSTACLE projects. Rover features applications and tooling required to address complex research fields such as cloud communication, open-source tooling, multi-core and cluster computing. Rover is equipped with powerful sensors, motors, and display units to interact with the physical world. Rover software, called roverapp features a multi-threaded (POSIX threads or Pthreads) C/C++ implementation that runs on Linux-based embedded single board computers (such as Raspberry Pi). Rover features countless threads dedicated to communication infrastructure (MQTT, REST API, Node.JS, TCP), sensor driving, display unit (such as OLED displays) utilization, bluetooth communication, image processing, and behavior modes (such as Parking, Adaptive Cruise Control, Manual Driving, and Booth Modes). It also features drivers for sensors such as magnetometers, accelerometers, various ultrasonic sensors, and camera modules. Furthermore, OLED display, buttons, a buzzer are utilized.

IOTA Client: An Easy-to-use Home Automation Node with OLED Display(Self Project)

February 2017 -

This project will be the client node of the Home Automation network I'm trying to create with my own possibilities. While the server node simply is a SBD with a touchscreen, a server and hotspot capability (also can be an Android phone), the clients will be powered with ESP8266-12 wifi modules and an optocoupler and snubber protected relay to control house appliances. The client node will provide an OLED display and a rotary knob for control. This fun project not only uses open-source free software for its design (KiCad) and implementation (STM32, Keil, EWARM), but also hopefully will enable people to be able to control gadgets in their home freely. I plan on improving the project with an Android app. Bear with me!

Development and Software Evaluation of a Distributed Multi-core Demonstrator
(Google Summer of Code Project !)

April 2016 -

A demonstrator system called A4MCAR has been developed which features not only low level functionalities such as sensor and motor driving but also high level features such as image processing, camera streaming, server-based wireless driving via Web, bluetooth connectivity via Android application, system core monitoring and analysis features and touchscreen UI. Our experiments along the multi-task heterogeneous demonstrator A4MCAR show that using APP4MC results instead of OS-based or sequential implementations on a distributed heterogeneous system significantly improves its responsiveness in order to potentially reduce energy consumption and replaces error prone manual constraint considerations for mixed-critical applications.
Technology overview: XMOS xCORE-200, Core monitoring, Partitioning/mapping, xC, Linux-Kernel, Raspberry Pi, Bash scripting, Software profiling, Python, TCP, PHP5/jQuery/Apache, Image processing, Touchscreen UI, Pthreads, Android, File I/O configurations.

Graphical Traffic Simulator and Embedded Real-time Warning System Development with Traffic RADARs(Master Project Thesis)

September 2016 -

Project Thesis in cooperation with Elektro-Prange GmbH and FH Dortmund
Real-world warning system that is developed is tested on Germany highways under the permission of a highway installation company. The real-world real-time congestion algorithm is developed so that it gets the refined version of the warning algorithm from the offline tests and it has to involve real-world interfaces inside. In the project, the real-world algorithm gets the RADAR-Signal Processing Unit data from an FTP server every 60 seconds and produces a warning output. The results obtained from the embedded warning system is tested using a Linux computer and the results prove the essential diagrams of the traffic stream. The obtained congestion levels showed the backward movement of congestion as well as the flow-density relationships using a real system.
Technology overview: Traffic flow analysis, Nagel-Schreckenberg Model, RNSL Model, DM Model, Falcon Plus 3 RADAR, MATLAB, Beaglebone, Python.


uComm - A Portable Terminal with TCP/UART/CAN-BUS capabilities(Self Project)

Technology overview: Python, Pygame, Touchscreen, Linux/Bash, UART, CAN-BUS, TCP, File I/O configurations.

Details will be added later..

Modelling and Controlling a Quadcopter (Course Project)

January 2016

Me and my colleague Jared have developed a model of a quadcopter and its sensor network using Simscape, then went through hoops to control it using some inputs. This work has been completed as a course project for the Control Systems course in Fh Dortmund, and it was really fun developing such a huge Simulink model. I've taken the liberty of designing a GUI for that afterwards. We are now able to control it using trajectory inputs as well as velocity and direction control.


Two Large Digital Clocks On VGA Using VHDL (Course Project)

Adaptive Cruise Controller Module Design for Electric Vehicle OSKAR (Bachelor Thesis)

July 2014 – July 2015

Adaptive Cruise Control (ACC) is a prominent system among the inteligent vehicle technologies which avoids the trafic accidents. Driver originated traffic accidents can be reduced by widespread usage of Adaptive Cruise Control system in vehicles. In this project, we design an Engine Control Unit for an electric vehicle, using ARS-308 long range RADAR, an hall-effect encoder, throttle sensor and a touchscreen display unit and by applying linear and nonlinear control techniques. We use STM32F407VGT06 microcontroller alongside the Raspberry Pi and use peripherals and protocols such as CAN-BUS, TCP/IP, USART, QEI, ADC, DAC along with an RTOS scheduler. We intend to use PythonQT for the developement of the high-level controller, in this ongoing project.


Autonomous Indoor Robot Navigation Using Kinect Sensor


In this project we aim to achieve a series of robot behaviours using Xbox 360 Kinect Sensor as laser scanner. We use ROS (Robot Operating System) and Gazebo Simulator while developing behaviours like Move To Goal, Passing Corridoor, and Passing Through Door. The application that we have developed on ROS will use a Finite State Machine in order to switch between behaviours, on a certain map. In addition, we use potenfial fields method for obstacle avoidance.
