Design Of A Self-Learning Prosthetic Hand Using Wireless Data Transmission and Flex Sensor

The project aims developing a prosthetic hand that can transfer data received from the flex sensor glove wirelessly and memorizing the desired movement. Prosthesis hand designs were examined and two of them were printed by 3D printer. In order to detect the desired movement of the hand, flex sensor glove was made. Flex sensor glove uses XBee for wireless data transmission.Movement of the prosthetic’s fingers is provided by servos. When the motors stretch the line the fingers close and when they release they open. A keypad is added for reducing the use of gloves. Once the desired movement has been registered, a key can be easily switched.As a result; a learning, RC prosthesis design which is open to development has been developed.

The Invisible Pollution of Sea Water

This project began on a beach, with an experiment, triggered by an image to become a concept: The Invisible Pollution of Sea Water. We thought of microplastic, quite nefarious, invisible and so abundant that removing it from the sea is highly challenging. This project is a driver for evolution, shifting mentalities and fostering social and scientific changes in unconventional ways; by engaging the community, you not only build a cheap and doable underwater remote operating robot / vehicle (ROV) or provide data for scientists, manipulate equations and laws of STEM found everywhere in our ROV but also interact and send pictures of our shores via a platform web that forms, informs and collects information and funds as well. From nothing we make something and from zero we will go hero.

Remote Controlled Cylinder

This research work consists of the conception and open-source development of a robotic cylinder whose speed is remotely controlled through a web page. To induce the movement, an innovative approach has been developed, which uses the coordinate movement of three motors to move a mass inside the cylinder. As the mass is placed away from the center, an imbalance is induced, causing the cylinder to accelerate. This project is very transdisciplinary, which is what makes it especially interesting: mathematics, physics, mechanics, electronics and programming notions were necessary to build the final prototype. It weighs 1.4 kg, has a diameter of 32 cm, an autonomy of about 4 hours and a maximum speed of 1 m/s.

Evaporative desalination with industrial waste heat

One of mankind’s biggest threats is the ever growing water shortage. One way to solve this is to clean seawater. Today more than 300 million people get their water from desalination plants around the world. Conventional desalination is however both expensive and energy demanding. Therefor i have developed a new way to desalinate seawater by utilizing water’s evaporative properties together with industrial waste heat, reducing the cost of cleaning 1000 liters of water to just 0.06€. Industries use 20% of freshwater around the globe and 60% in wealthy countries so self sustaining factories through my invention would be a huge step towards securing the water supply in the future. I am now leading a full-scale pilot project in Sweden capable of cleaning 40.000 liters/day with a local smeltery.

Next generation of solid-fuel rocket engines

Using of powdered fuel is almost impossible during all history of rocket engines. It burns so fast that the gas pressure destroys the engine’s casing. To solve this problem the fuel is pressed usually and an inhibitor is added. In my research I developed a new technology of controlling pressure inside the solid-fuel rocket. It simplifies greatly the process of making engines, allowing adjusting their parameters to get the maximum thrust safe pressure inside engine. Using this technology I created a working small engine for rocket modeling. It was tested and works well in real flights. I will continue the research of my new technology to understand its limits, increase efficiency and possibility to scale up for bigger appliances. It’s the next generation of solid-fuel rocket engines.

High Altitude Micro Air Vehicle

Stratospheric missions allow us to forecast the weather and broaden our horizons in many fields, ex. astrobiology. Whenever we send a balloon into the stratosphere it gets blown off course which makes it hard to find and retrieve the experiment. We designed a drone that could, after being lofted into the stratosphere suspended from a balloon, return with a payload to the location of launch. We produced a prototype that we put through a series of tests, during which it became the worlds’ first micro class drone to return from the lower layers of the stratosphere carrying a scientific payload. The data and experience we gathered allowed us to outline a path for development of the HAMAV, that we are currently following in order to ready the drone for a voyage 30km above the earth’s surface.

Motorised Platform for Inverted Microscopes Olympus IX 50 and IX 70

Moving samples at high magnification manually is not easy and purchasing motorized platforms often is not affordable.This brings about the idea of building a platform from scratch, through Open Source tools and under Creative Commons license, making the project a starting point for further developments as well as an incentive for young people who may want to experiment.The minimum movement along the axes equals ~27nm. The platform allows to automatically go back to a previously saved position, with a tolerance of ~30µm. A display shows the current position and so it is possible to take note of all interesting positions to go back there.Finally, the automatic positioning at the center of the microscope upon turning on, guarantees that the positions remain valid even upon restart.

Improving recovery time of patients with an Ilizarov external fixator around the ankle

The Ilizarov apparatus is used in orthopedic surgery to treat complex fractures by using an external ring around the ankle to fixate the limb in order to lengthen and heal the bone. When the fracture occurs in the ankle area the bottom ring is often located under the foot and prevents the patient from bearing weight on their broken limb. Weight bearing is essential to the recovery process.Our project provides a method for patients with an Ilizarov apparatus fixated at the ankle area to bear weight on their leg, improving the recovery time for such fractures.

Moth.NET

Pests can ruin every healthy tree crop within 10-15 days. If pest-control is executed, 50-75% loss may occur. Observation, forecast, prevention. These three words can describe my project.How is it possible to keep track about all of the pests inside the fruit? – I developed a system which can monitor the insect traps. In this trap there is a high-quality camera and a monitoring microcontroller. The automated pheromone trap what I developed would be effective for farmers for economical, environmental protection and environmental reasons. It helps the owner to buy the right amount of pheromone, glue and spray, so you can plan financially.

Hoverboard – a Magnetically Levitated Vehicle

In the science-fiction classic „Back to the Future II,“ actor Michael J. Fox whizzes through the streets on a skateboard that has no wheels – it floats over the ground like a hovercraft. This is precisely the technology that Felix Sewing and Alex Korocencev have been puzzling over. Their vehicle is based on four rotating discs that can induce a powerful, repulsive magnetic field on a metal plate located beneath it. The load capacity of the board is impressive indeed: the prototype can lift a considerable weight. In addition, the rotor discs can be tilted individually, allowing the board to be purposefully steered. The technology functions so well by this point that the two young researchers have even been able to apply for a patent covering the new arrangement of the magnets.

Triboelectric Curtain

This is an eco-friendly electric station producing enough green energy in an unique way from wind at any time of the day. We take one couple of materials: one has a negative charge and the other has positive, then we place a conductor on each of them. When they touch each other, they exchange charges. After these 2 sides get separated voltage between them rises. This is “Triboelectric Effect” but we discovered that here also works electromagnetic field. When curtains are exchanging charges, they move to each other & vice versa, but mostly this action is accelerated, so we get induced electromotive force between those conductors. Invention is eco-clean as these materials can be recycled; cheap & easy to construct requiring no special professionals; durable as materials are self-cleaning.

BoneSound

Bone conduction headphones offers the possibility to listen music to deaf people. The bone conduction is a sound propagation method that passes sound not through the air but through bones onto the ears. Hearing people can also listen music, additional the environment noises. We choose to propose a system based on simple components. The aim was to put forward assembly plan accessible to everyone, for a self- manufacture, much less expensive (approximately 50€) and custom-made. All of our work and researches are gathered on a website. We coded a software to optimize the listening of music with the bone conduction. Indeed, bone conduction absorbs some frequency differently than others. Also, we need to be able to rise to volume without overloading the music.

The wingtip’s influence on the efficiency of airplane wings

Aviation is one of the most important ways of transortation. However, it is highly energy consuming and has a substantial climate impact. In this project, I have designed and tested a new type of wingtip device called a New Raked Wingtip. The New Raked wingtip optimizes the three-dimensional flow around the wingtip in order to maximise the lift and minimise the drag on the wing. That is, maximising the wing’s efficiency defined as the ratio between the lift and the drag. Experiments that I have designed and carried out show that the New Raked Wingtip not only increases the efficiency of the wing, but also increases the efficiency more significantly than currently used wingtip devices. Implementation of New Raked Wingtips has the potential of dramatically reducing aviation’s climate impact.

Affordable 3D-printed Equipment for Innovative Robotics Education

This project deals with the development of 3D-printed models, electronics and software for innovative education in robotics, sufficiently cheap to allow the schools (technical or vocational, as well as re-qualification courses or hobby clubs) to afford them for all their students in the class. Each and every student might make/repair/improve his/her own robots from a scratch and naturally “learn-by-making” multiple subjects from CAD modeling and 3D printing to electronics assembly to coding on multiple platforms. The models developed so far include the universal control system for a wide range of 3D-printed robotic manipulators, and a robotic model of a human hand, controlled wireless via a sensory glove and expandable with future advanced modules (muscle control, computer vision etc).

An Intelligent Directional Following Device Based on Ultrasonic Positioning and Robust PI Controller

The project designs an intelligent directional following device based on ultrasonic positioning and strong robust PI controller. It locates and follows directly under the beacon’s guidance, which brings fast calculation, high positioning accuracy and sensitivity, low energy consumption, and easy control. New algorithm based on four receiving sensors also makes positioning more accurate. Using robust PI controller let it move much steadier and more adaptable to complex environments, with strong anti-interference ability. Its warning system ensures safety and no touching obstacles. Moreover, 3 highly reliable Omni-Wheels, 120° apart, make it move instantaneously in any direction. The device can be widely used indoors and has been granted two patents and won the National Gold Medal.

An Interpretation of Life Through Vibration Motors

Independent travel and the ability to interact with the world are two of the greatest challenges facing blind/ visually impaired (BVI) persons. Traditional tools, such as the white cane and guide dog, are limited and do not provide users with the information they need to navigate effectively and gracefully. I worked to develop an advanced electronic travel aid that uses ultrasonic sensors and LIDAR to provide BVI users with enhanced spatial perception through vibro-tactile feedback. The device was developed to equip users with a tool to overcome their social and navigational challenges and give users the confidence and comfort to explore independently.

Diffrec PRO

The team developed a so-called differential pulley block for alpine lightweight synthetic fibre ropes, which will be easy and simple to handle. They calculated and compared different concepts and found a serrated differential roller with three differently sized grooves. The axle of the pulley is suspended from two side plates, which also provide a suspension point for a carabiner. A mechanism presses the rope into the serrations so that it doesn’t just let go. They found a very smart solution for the improvement of pulley blocks for alpine applications.
