Machine Learning System Development in a Virtual Environment for Industrial Robot Training

Artem Grukhal
School of Engineering, Tallinn University of Technology

This project consists of several practical parts which are subject to research as well:

  • Finding solutions on manipulating the robot arm with it’s digital twin using coordinate systems (as opposed to changing joints’ angle values).
  • Implementing machine learning in Virtual Environment.
  • Transferring machine learning knowledge from digital twin to a real robot. 

All of them require prior knowledge, practical implementation and posterior analysis in order to consider the project be successful. 

Anti-Trash: Monitoring Cleanliness of Public Transportation with Computer Vision

Risto Ojala, Tuomas Kinnunen, Joel Mattila, Mikael Aakko
School of Engineering, Aalto University

Due to the global trend of urbanization, the demand for public transportation is ever-increasing and public transportation vehicles will likely be autonomously operated in the near future, creating a need for advanced surveillance systems. In this study, a computer vision system capable of evaluating the cleanliness of a public transportation vehicle interior is presented.

Realistic Environment Mapping and Integration to Unity 3d

Baris Cem Baykara
School of Engineering, Tallinn University of Technology

This project consists of the following parts

  • Develop and test autonomous vehicles
  • Efficient testing of vehicles in different terrain types
  • Safety Validation

Bending and Cutting Coaxial Wires for Cryostats

Fernando Marquina Magaña, Antti Honkanen, Diwakar Gupta
School of Engineering, Aalto University

Quantum computers can solve problems that are impossible or would take a traditional computer an impractical amount of time to solve. Coaxial lines are used to communicate with the quantum chip inside of the cryostat because of their fast data transfer ability and low thermal conductivity. This project presents a fully automated device designed for bending and cutting the coaxial wires used in quantum computing cryostats.

Bowling Assistant

Sampo Laine, Topias Turunen, Martin Guggemos
School of Engineering, Aalto University 

The aim of this study is to create a device to easily enhance your bowling performance. Typically, the current systems emphasize the movements of the ball. In this study a different approach was taken, and the measurement system is centered on the movements of the bowler. The feasibility of methods applying inertial measurement systems was evaluated, and the results indicate that adequate performance can be achieved with the low-cost inertial measurement units.

Bachelor Course Project

Fathin Dosunmu
School of Engineering, Tallinn University of Technology

This project consists of the following goals

  • Goal 1: The goal is to develop a machine learning model that would predict if a student is likely to continue studies at Tallinn University of Technology after the 3rd semester of studying based on statistics of university students collected from Tallinn University of Technology.
  • Goal 2: Compare various machine learning algorithms, compare the pros and cons, and conclude on what algorithm is suitable to solve our problem.
  • Goal 3: (Future Goal) ……would be really nice to integrate my ML model with a software application and make it interactable for people. Perhaps sell the product and allow other universities to input their data and obtain their own predictions….

Escape Room

Vili Juustila, Jani Vihko, Tuukka Uimonen
School of Engineering, Aalto University

Due to their engaging nature, escape rooms are an interesting alternative teaching method. Studies in other fields have shown educational escape rooms to improve motivation and learning. In this study, an escape room with three mechatronic puzzles is created. The puzzles are designed for high-school students with a combined time limit of 10 minutes. 

Upper Extremities and Body Movement Assessment Using Markerless Motion Capture

Marietta Gavriljuk
School of Engineering, Tallinn University of Technology

The aim of this  project is to create a game-based rehabilitation solution for shoulder ability improvement. The project consists of the following parts

  • Develop a game-based application with the help of Microsoft Kinect to implement several training activities. 
  • Create a virtual upper-body rehabilitation assessment for patients who suffer from shoulder’s movement disability 
  • Optimize the application for the data collection and analysis

Hardware-In-the-Loop Test Setup

Elisa Alboni, Ville Björklund, Matti Lin, Heikki Lu
School of Engineering, Aalto University

The semi-active hydraulic suspension systems are becoming increasingly popular since they offer high performance compared to traditional solutions. The damping coefficient of semi-active dampers is varied by adjusting the proportional valve. This study proposes a light and cost-effective single board computer (SBC) based hardware-in-the-loop (HIL) simulation test setup for testing and tuning semi-active suspension systems. 

Laser Induced Breakdown Spectrometry 

Jonas Mård, Verneri Vilmi, Jonas Rintanen
School of Engineering, Aalto University

Laser Induced Breakdown Spectroscopy (LIBS) works by shooting laser light onto an optical system that focuses the laser beam on the sample. This creates a plasma emitting light. This research addresses a design of a stand-off system that scans the environment with varying distances. The device is based on a Newtonian telescope model, whereas the target is to fit most of the optical components on the same optical axis. 

Calibration of Lab Equipment Using Augmented Reality

Merih Kaner 
Integrated Engineering, Tallinn University of Technology

The purpose of the project:

  • To create a platform where user can enter instructions and match them with markers to be viewed later in AR
  • Initially for laboratory equipment, but it can be extended further.
  • Currently it is at the prototype stage and usable on phones and tablets.

Powder Removal Device for Metal 3D Printing

Raimo Vepsäläinen, Christian Ranta, Juho Lavio
School of Engineering, Aalto University

Printing metal parts with overhangs on powder bed-base, support structures are needed. Metal powder trapped inside the support structures needs to be removed before post-processing. Manual powder removal is an intensive and time-consuming process and can also pose safety risks, such as respiratory damage. In this study, a design for automatic powder removal device for metal additive manufacturing is proposed. 

Slinging InTerrain

Sean Connor, Mikko Heliö, Aleksi Kuuva, Paavo Palomäki
School of Engineering, Aalto University

While the need to reorient crane loads in-air exists, only a few products are available on the market which attempt to fulfill this specific purpose, but there exists inherent limitations. This study describes an under-the-hook device that allows re-orientation of a load during an overhead crane lift. 

3D Printable Wide Filter Smart Respiratory Mask

Seycan Kuntay Baykara  
School of Engineering / Integrated Engineering, Tallinn University of Technology

The aim of the project is to

  • Create an easily printable and reusable mask.
  • Being able to tell the temperature inside the mask.
  • To cut the long-term costs for institutes (medical, industrial, engineering).
  • Especially, to help medical professionals with providing much needed masks.

Temperature Behavior of Flat Type Linear Motor 

Robert Hermansson, Mehrdad Khodayari, Muhammad Usman, Kimmo Hirvonen
School of Engineering, Aalto University

The common problem with linear motors is the heat production, which limits the performance and reduces the accuracy. In this research, temperature behaviour of Flat Type Linear Motor Carrier is simulated and verified with actual temperature measurements, and the accuracy of the applied methodology is evaluated.
