    Authors: Hallist, Martin;

    Eesti keeles: Robootika kiire areng toob kaasa vajaduse tarkadeks robotiteks. Veel ei ole loodud lahendust, mis oleks sama kohanemisvõimeline kui inimene. Seepärast on praegune parim lahendus luua vahendid inimeste ning robotite koostööks. Paraku ei kasutata potentsiaali piisavalt ära ning paljud robotite juhtimissüsteemid on kohmakad ning ebamugavad. See motiveerib looma süsteemi, mida oleks kerge ja mugav juhtida. Lõputöö keskendub teiste sarnaste lahenduste ning vajalike töövahendite tutvustamisele. Peamiseks nõudeks on manipulaatori vaba liikumine. Selle tulemusena valmis kaugjuhtimise lahendus, kus robotmanipulaator liigub vastavalt käte liikumiskiirusele ning pöördenurgale. In English: The rapid development of robotics raises the need for smart robots. There are no solutions yet that are as adaptable as a human beings. Thus, the current best solution is to create solutions for collaborations of humans and robots. Unfortunately a lot of potential is wasted, making controlling systems awkward and aggravating. It gives motivation to create a system that is easy and comfortable to maneuver. The bachelor’s thesis focuses on other similar solutions and gives an overview about used tools and modules. The main requirement is free movement of a manipulator. As the result, the teleoperation solution is made, where the robot manipulator moves according to the speed of movement of the hands and follows the angle of rotation.

    Authors: Julle, Kätriin;

    Eesti keeles: Mobiilne robot KUKA youBot on oma funktsionaalsuselt päevakajaline nii teaduse kui õppetöö eesmärkidel, sest tegu on omniliikuva mobiilse manipulaatoriga. Ent roboti pardaarvuti (Intel Atom D510 Dual Core 1.66 GHz, 2 GB DDR2 RAM) on vananenud ja tootja poolt toetatud tarkvara (ROS Indigo ja Ubuntu 14.04) aegunud. Seetõttu oleks vajalik robot ajakohastada nii, et seda saaks kasutada kaasaegsetes lahendustes. Roboti ajakohastamiseks asendati KUKA youBoti pardaarvuti Intel NUCiga (Intel Core i5-4250U, 4 GB DDR3 RAM) ja paigaldati ROS Kinetic ning Ubuntu 16.04. Riistvara ja tarkvara uuendamise tulemusena tõusis KUKA youBoti pardaarvuti jõudlus. Suurim muutus toimus manipulaatori liigutusplaneerimisele kulunud ajas, mis vähenes enam kui 100 korda. In English: Mobile robot KUKA youBot is functionally relevant in research and education purposes because it is a omnidirectional mobile manipulator. But the robot’s onboard computer (Intel Atom D510 Dual Core 1.66 GHz, 2 GB DDR2 RAM) and the software the manufacturer supports (ROS Indigo and Ubuntu 16.04) are out of date. For that reason the robot needs to be brought up to date so it could be used in modern solutions. To bring the robot up to date, KUKA youBot’s onboard computer was replaced with Intel NUC (Intel Core i5-4250U, 4 GB DDR3 RAM) and ROS Kinetic and Ubuntu 16.04 were installed. As a result of upgrading The hardware and software, KUKA youBot’s performance increased. The biggest change could be seen in the manipulator’s movement planning time, where it decreased more than a 100 times.

    Authors: Kivastik, Joosep;

    In this thesis a diffraction limited optical design for a radiometrically calibrated miniature multispectral Earth observation imager is proposed and its performance analysed. The goal of the imager is to capture quantitative data for remote sensing with a radiometric accuracy of 5% during a three year lifetime in Low Earth Orbit. The design is based on optical and radiometric requirements that were derived from a radiometric budget analysis and the requirements from the original proposal. The budget also set requirements for different optical components which were chosen as part of this work. A tolerance analysis was performed on the optical design taking into account the uncertainties from manufacturing and assembly. It was found that instrument design fulfills the original requirements and it will be used to build a prototype instrument for the European Space Agency. Magistritöö raames töötati välja radiomeetriliselt kalibreeritud miniatuurse multispektraalse maavaatluskaamera difratksiooniga piiratud optiline ülesehitus ning viidi läbi selle kvaliteedi analüüs. Kaamera eesmärk on kolmeaastase eluea vältel Maa-l¨ahedasel orbiidil jäädvustada kvantitatiivseid kaugseire andmeid, mille radiomeetriline täpsus on 5%. Kaamera optiline ülesehitus põhineb optilistel ja radiomeetrilistel nõuetel, mis tulenevad projekti esialgsest kirjeldusest ning radiomeetrilise eelarve analüüsist. Eelarve tingis nõuded ka teistele optika komponentidele, mis valiti välja selle töö käigus. Optilisele disainile tehti ka tolerantsianalüüs, mis põhines kaamera valmistamisel ning kokkupanekul tekkivatel määramatustel. Analüüs näitas, et kaamera disain vastab algupärastele nõuetele ning sellest lähtuvalt ehitatakse prototüüp Euroopa Kosmoseagentuuri jaoks.
