The paper presents a process of designing and building software for a robotic test stand used for inspection of stators. The software was developed for a test stand comprising the ABB IRB 140 robotic manipulator, and a PC workstation that handles two ultrasound sensors and runs the LabVIEW software suite. The control algorithms of the robot include the potential differences in the geometric features of the items inspected on the test stand and the resulting differences in the manipulator tool motion paths. The software was designed for and delivered to Pratt & Whitney Rzeszów Sp. z o.o.

Зараз, медичні процедури з використанням іонізаційного випромінювання , для лікування або діагностики, є дуже поширеними у всіх країнах світу. Згідно останніх досліджень, середній рівень впливу іонізуючого випромінювання на населення – зростає. Останні дослідження показують, що розробка більш складних і тривалих процедур діагностики та лікування з використанням іонізуючого випромінювання, у поєднанні з збільшенням доступності цих процедур та більшою кількістю пацієнтів неминуче призводить до збільшення опромінення персоналу лікарні. Ефективність радіаційного захисту працівників, які працюють з даним типом випромінювання, значною мірою залежить від розуміння радіаційного поля, якому вони піддаються.. Саме тому актуальною є розробка пристрою для 3D-вимірювання рівня радіації і може дозволити знизити дози опромінення персоналу, при виконані процедур з використанням радіаційного випромінювання. Now, medical procedures using ionizing radiation, for treatment or diagnosis, are very common in all countries of the world. According to recent studies, the average level of exposure to ionizing radiation on the population is increasing. Recent studies show that the development of more complex and lengthy diagnostic and treatment procedures using ionizing radiation, combined with the increased availability of these procedures and the larger number of patients, inevitably leads to increased exposure to hospital staff. The effectiveness of radiation protection of workers who work with this type of radiation largely depends on the understanding of the radiation field to which they are exposed. That is why the development of a device for 3D measurement of the level of radiation is relevant and can allow to reduce the doses of exposure to personnel, if procedures are performed using radiation.

Fren hortumunu tekerlek ve şasi arasında kendisi için bırakılmış olan boşlukta güvenli bir şekilde yerleştirilmesi gerekmektedir. Bu dar hacimde çevre parçalara temas etmeden ve üzerinde aşırı eğilme ve burulma gerilimlerine yol açmadan uygun bir fren hortumu montaj şekli tespit etmek imalatçıların önemli sorunlarından birisidir. Fren hortumunun hareketlerinin benzetimler yoluyla kestirilmesi doğrusal olmayan dinamik yapılarından dolayı çok kolay değildir. Modellenen hortum yapısının pek çok parametreye bağlı hareketi üzerinde sonuç oluşturmak otomotiv firmaları tarafından güvenilir bulunmadığı için kabul edilen bir yöntem değildir. Bu makalede, otomotiv üreticileri tarafından verilen, araca ait hareket bilgilerinden yola çıkarak fren hortumu bağlantısı için en uygun yapının tespiti ve bağlantının olası hareketlerine ait CAD (Computer Aided Design) dosyalarının oluşturulması süreci için geliştirilen yöntem tanıtılmaktadır. Robotik kollar ile fren hortumunun araç üzerindeki hareketleri canlandırılırken kameralar yardımıyla hortumun aldığı şekil yüksek kesinlik ile belirlenecektir. Kameralar tarafından elde edilecek nokta bulutları daha sonra müşteriye verilecek 3D CAD verisine çevrilecektir. Böylece müşteri diğer bileşenler ile çarpışma risklerini değerlendirebilecektir. Bu sistem ayrıca kalite kontrol ölçümleri için de kullanılabilir. The brake hose should be freely assembled in its own space between the steering and the chassis. In this narrow volume, without contacting to the surrounding components and without extreme bending and torsional forces, obtaining a proper routing is one of the important problems of the manufacturers. Predicting the motion of the brake hoses via simulations is not straightforward because of their nonlinear dynamic structures. Presenting any result for the hose structure which has too many parameters via simulations is not an accepted method for automobile manufacturers because of unreliability. In this study, a methodology to determine the optimum routing for brake hose assembly bound up with vehicle dynamics, given by automobile manufacturers and to build up a CAD files of all different potential postures is introduced. Shape of brake hoses will be determined by the vision system with high preciseness while robotic arms are animating the hose motion. Point clouds supplied from optical systems will be converted to CAD data for the customers. Thus the customer can evaluate contact risks within the other components. This system can also be used for the quality control measurements.

- Abstract
This dissertation addressed three critical issues in developing a robot measurement system are addressed, i.e., system self-calibration, system accuracy maintenance and path planning. A self-calibration method, based on relative measurement instead of Cartesian coordinate measurement, is proposed to calibrate the robot measurement system on the manufacturing floor. Compared with traditional calibration methods this self-calibration is more advantageous in terms its implementation and the accuracy of parameter estimation. In order to achieve the high accuracy required by a robot measurement system, nongeometric errors such as compliance and thermally-induced errors have to be taken into account. The effect of compliance errors and thermally-induced errors on the robot measurement system performance is under investigation. A general methodology has been developed to calibrate these errors. Principal component analysis and orthogonal regression are used to construct the empirical models so that the thermally-induced error can be compensated for by monitoring the system's temperature field, therefore the system's accuracy can be maintained. An optimal path planning algorithm is developed for the robot measurement system with an area sensor. The method integrated techniques from geometric modeling, integer programming, principal component analysis and sphere package to generate the position and orientation for the sensor frame based on the object's geometric representation. Linear programming techniques has been used to determine the sequence so that the sensor follows a shortest path.
