    Design and Control of a Social Humanoid Robot - SemuBot’s Hand
    (Tartu Ülikool, 2024) Huseynov, Elchin; Aabloo, Alvo, juhendaja; Zinatullin, Leonid, juhendaja; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Tehnoloogiainstituut
    Children can find socialising difficult due to communication problems and a lack of comprehension of social cues[1], which can lead to isolation, marginalisation, and difficulties building social bonds. Social robots are an effective solution to this problem[2]. But, social robots need to be embodied as a humanoid for children to create a will to socialise with the robot. There are several versions of social humanoid robots. However, most are prohibitively expensive and difficult to repair because they’re closed-source. SemuBot is one of the projects that aims to solve these issues and help tackle children's socialisation issues. Semubot is a student-led, nonprofit organisation. This work pertains to the arm and the forearm parts for the SemuBot. Natural interactions between machines and humans require the robot to display body language, requiring robotic hands. However, the hand designs that are currently available either have expensive and/or noisy actuation systems. Some also have insufficient degrees of freedom, limiting the number of gestures they can make. In this work, we present an open-source, modular hand with 7 actuated degrees of freedom. The design incorporates a bio-inspired tendon-driven actuation mechanism, which uses cost-effective materials and off-the-shelf components to achieve common hand gestures.

    Robotbaarmen
    (Tartu Ülikool, 2017) Reinumägi, Risto; Aabloo, Alvo, juhendaja; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Tehnoloogiainstituut
    Selle bakalaureusetöö eesmärgiks on uurida tehnilisi võimalusi, et prototüüpida robot, mis suudab valmistada erinevaid kokteile, nõudes kasutajalt minimaalset sekkumist. Töös antakse ülevaade maailmas selles valdkonnas tehtust, tuuakse välja erinevate lahenduste eelised ja puudused ning klassifitseeritakse lahendamist vajavad uurimis- ja inseneriprobleemid. Samuti antakse ülevaade võimalikest ärimudelitest taoliste seadmete valdkonnas.

    TheiaVision: ultrasonic glasses for people with visual impairment
    (Tartu Ülikool, 2014) Soo, Sander; Aabloo, Alvo, juhendaja; Anbarjafari, Gholamreza,juhendaja; Tartu Ülikool. Loodus- ja tehnoloogiateaduskond; Tartu Ülikool. Tehnoloogiainstituut
    There are a lot of people living in the world, whose eyesight is either very poor or who cannot see at all. People with visual impairment have a wide variety of tools and other resources available to them. The exact choice depends on the specific needs and vision remainder of the individual. However, most of these devices have some form of disadvantage to them, whether it is high price or the fact that they are mostly seer-oriented, with only some applications to expand their capabilities to also make them helpful to the blind and visually impaired community. TheiaVision is a system that was developed in the course of this thesis, which actively monitors the immediate surroundings of the individual with the help of ultrasonic sensors. Based on the measurements obtained, the system warns the user of obstacles that are in a too close proximity, thus helping people with vision disorders navigate the environment a bit easier. The system can be developed further by adding various features, such as GPS navigation and voice commands, to further simplify the life of the user.
