    Arbuskulaar-mükoriissed (AM) seened aitavad taimedel mullast toitaineid omastada, pakuvad kaitset stressi vastu ning parandavad mulla struktuuri. Tavapõllumajanduse praktikad mõjuvad AM seenekooslustele negatiivselt. AM seeni sisaldavaid inokulaate kasutades soovitakse inokulatsiooniga taimede kasvu ja saagist parandada, kuid inokulaate uurinud tööd on leidnud nende efektiivsuse kohta vastakaid tulemusi. Oma magistritöös uurin potikatses 11 tööstusliku inokulaadi võimet taimejuuri koloniseerida, neis sisalduvate AM seente ja muude mikroorganismide mõju taime biomassile ning tootekirjelduses olevate AM seeneliikide vastavust tegelikule koostisele. Leidsin, et vaid kaks inokulaati tekitasid taimedel juurte kolonisatsiooni ning inokulaatides olevate AM seened ja muud mikroorganismid ei omanud olulist positiivset mõju taimede biomassidele. Inokulaate sekveneerides tuli välja, et tootekirjelduses olevad AM seene liigid ei vasta suures osas neist leitud liikidele ning mitmes tootes oli AM seeni väga vähe või puudusid nad sootuks. Seega tuleks AM seeni sisaldavate inokulaatide tulemuslikuks rakendamiseks pöörata senisest suuremat tähelepanu inokulaatide kvaliteedikontrollile.

    Authors: Pihlap, Meelis;

    Robots enable us to operate in hazardous or otherwise unvisitable environments such as mines, fires and radioactive environments. TeMoto, which is built upon the Robotics Operating System (ROS), makes it easier to develop scalable, manageable and reliable software for robotics systems. TeMoto needs functionalities to represent the environment in order to support development of robot systems that are aware of their surroundings. The aim of this work is to plan and design a framework for working with environment models, enable robots to synchronize the environment data, create an environment model to match the framework and test the system in a real world scenario. This was achieved by implementing data structures representing objects and rooms/spaces in the, designing an abstract interface to work with the data structures and implementing the interface to create a corresponding environment model. The work resulted in a functional system and infrastructure, which allows sharing semantic and topological data between robots, which was demonstrated in a trash collecting mission featuring a heterogeneous multi-robot system. The implemented framework lays a foundation for use of environment models in TeMoto, which allows designing robot systems that interact with the world in a meaningful way. Eesti keeles: Robotid võimaldavad töötada eluohtlikes keskkondades või muul moel ligipääsmatutel aladel nagu näiteks kaevandustes, tulekahjude kustutamisel ja radioaktiivsetes keskkondades. Hõlbustamaks inimene-robot ja robot-robot koostöösüsteemide tarkvaraarendust on loodud robotite operatsioonisüsteemil (ROS) põhinev tarkvararaamistik TeMoto. TeMotol on vaja keskkonna esitamise funktsionaalsusi, et oleks võimalik arendada robotisüsteeme, mis on keskkonnast teadlikud. Töö eesmärgiks oli kavandada ja luua TeMoto arhitektuuris raamistik keskkonnamudelitega töötamiseks, luua funktsionaalsus keskkonnamudelite sünkroniseerimiseks TeMoto instantside vahel, pakkuda keskkonnamudel ja testida süsteemi reaalses stsenaariumis. Töö tulemusena valmis terviklik süsteem ja infrastruktuur, millega saab edukalt jagada semantilist ja topoloogilist informatsiooni mitme roboti vahel ja seda demonstreeriti heterogeense mitme roboti süsteemiga läbi viidud otsingumissiooni näitel. Implementeeritud TeMoto keskkonnamudeli raamistik paneb aluse keskkonnamudelite kasutusele TeMoto arhitektuuris, mis võimaldab TeMoto abil arendada keskkonnaga mõtestatult tegutsevaid robotsüsteeme.

    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.

    Arbuskulaar-mükoriissed (AM) seened aitavad taimedel mullast toitaineid omastada, pakuvad kaitset stressi vastu ning parandavad mulla struktuuri.

    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.
