Mechatronic Circus 2020
Mechatronic Circus is an annual event where students present the smart devices they have built on the mechatronics courses. Unfortunately this year the public event that has normally gathered up to 500 visitors had to be cancelled, but the students and their teachers held the event virtually. Below you can find information on the student projects including posters and presentations of each team.
Monitoring Cleanliness of Public Transportation with Computer Vision
Risto Ojala, Tuomas Kinnunen, Joel Mattila, Mikael Aakko
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.
Bending and Cutting Coaxial Wires for Cryostats
Fernando Marquina Magaña, Antti Honkanen, Diwakar Gupta
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.

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.

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.
Hardware-In-the-Loop Test Setup
Elisa Alboni, Ville Björklund, Matti Lin, Heikki Lu
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
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.
Powder Removal Device for Metal 3D Printing
Raimo Vepsäläinen, Christian Ranta, Juho Lavio
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.

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.
Temperature Behavior of Flat Type Linear Motor
Robert Hermansson, Mehrdad Khodayari, Muhammad Usman, Kimmo Hirvonen
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.
