This diploma thesis deals with a design and construction of a two-wheeled mobile robot. In order to prepare a high-quality project, a testing carriage has been constructed serving as a basis of useful information for the final design and construction. Beside introduction and conclusion, the diploma thesis consists of four main parts. While the first part of the thesis briefly introduces the field of robotics, the theoretical part focuses both on particular components necessary for the robot's construction as well as the Segway vehicle which served as an inspiration for the robot's functionality. After characteristics of a testing carriage, attention is devoted to individual methods of stabilization, with several different types of sensors being used. Furthermore, the chapter on mechanical design examines choice of devices and their position and provides a scheme for their construction. The electrical design follows afterwards, describing circuits that were considered optimal for the designed wiring. The forth part of the diploma thesis concentrates on the construction of a two-wheeled carriage and covers following topics: construction of mechanical components, production of electric boards, programmatic equipment of the carriage and its implementation, testing of the carriage and finally also an evaluation of achieved results.

We consider two models which lead to the prediction of a weight change of gyroscopes depending on the rate of rotation: mass-energy equivalence and Weber's force for gravitation. We calculate the order of magnitude of this effect in both models and show that Weber's model predicts a weight change depending on the spin axis orientation resembling close similarities to observed Earth flyby anomalies. however, our predicted effect is much smaller than the observed effect, which could explain why flyby anomalies were not detected anymore in recent spracecraft trajectories.

The whiteboard is a tool being used in several different facilities around the world. However, erasing the ink off the board can be unnecessarily time consuming and distracting. The purpose of the project was therefore to create a demonstrator to automate the process with a few restrictions. The demonstrator was required to be light enough and small enough to be handheld. In addition, the demonstrator needed to function and work properly on a magnetic surface. To conceptualize the purpose a demonstrator was built with an iterative process and thereafter programmed to get a systematic movement. It utilized continuous servo motors, IR-sensors and a 3-axis gyroscope and an accelerometer in combination with 3D-printed components. The final prototype turned out to function properly but could be improved as its erasing properties are not working as one could expect from a finished prototype. / Whiteboard är ett verktyg som används i flera olika fastigheter runt om i världen. Att ta bort bläcket från whiteboarden kan dock vara onödigt tidskrävande och distraherande. Syftet med projektet var därför att automatisera processen med några begränsningar. Två begränsningar var att prototypen skulle väga lite och vara tillräckligt liten för att vara handhållen. En annan begränsning var att den skulle fungera korrekt på en magnetisk yta. För att konceptualisera syftet byggdes en prototyp med en iterativ process och därefter programmerades den för att få en systematisk rörelse. Den utnyttjade kontinuerliga servomotorer, IR-sensorer och ett 3-axligt gyroskop i kombination med 3D-printade komponenter. Den slutgiltiga prototypen visade sig fungera korrekt men kan förbättras eftersom dess raderingsegenskaper inte fungerar som man kunde ha förväntat sig från en färdig prototyp.

Technology advances each day, with every advancement new and improved products are accompanied. Robots come in various shapes and sizes, from the size of a fly to the size of a human being. The purpose of this project is to further our understanding in how to build a robot, more specifically, a mono wheeled robot and design control systems enabling it to balance by itself. The robot is a one-wheeler with ducted fans on top. It is to balance with the help of the wheel in one direction and with ducted fans in the perpendicular direction.The robot succeeded in balancing with the wheel. However with help of the fans the robot only managed to balance for approximately 20 seconds. Analysing the frequency content from figures 5.2, 5.4, 5.3 resulted in finding frequencies under 1Hz being dominant in the output signals from the control system, observing this a clear oscillation frequency was only determined for the ducted fan system while the wheel system was non periodic. The study concluded that one cannot stabilize the control systems individually because that can lead to disturbances for the other. The results showed that even though the wheel’s control system was stable, it was affected by the second control system, causing disturbances. / För varje dag som går tar tekniken ett steg frammåt, hela tiden med nya och förbättrade produkter. Robotar kommer i olika former och storlekar, från storleken av en insekt till storleken av en människa. Syftet med detta projekt är att utvidga förståelsen över hur man bygger en robot, mer specifikt, en enhjulig robot samt hur man konstruerar ett reglersystem för att få roboten att balansera på egen hand. Roboten är en enhjuling med fläktar. Syftet är att bygga och programmera den till att balansera på egen hand, i ena riktningen med hjulet och i andra riktningen med fläktarna. Roboten lyckades balansera med hjälp av hjulet, men med fläktsystemet balancerade roboten endast i cirka 20 sekunder. Med hjäp av frekvenspspekrumen i figurer 5.2, 5.4, 5.3 försöktes en oscillationsfrekvens och periodtid tas fram, detta erhölls endast för fläktsystemet då hjulsystemet inte gav en tydlig oscillationsfrekvens. Slutsatsen som drogs var att det inte går att stabilisera de individuella systemen separat och sedan kombinera dem. Detta på grund av att det leder till att det ena systemet riskerar att agera som en störsignal till det andra systemet.

This thesis deals with theoretical description of fiber-optic angular velocity sensors, or gyroscopes, and further with design and construction of own sensor of this type. The theoretical part describes problematics of interferometric and resonant fiber-optic gyroscopes. Basic principles and physical limits are described for both types. The main focus is then put on analysis of possible conceptions of these sensors. Solutions using different optical configurations as well as various modulation and signal processing schemes are discussed. The practical part deals with design and construction of own interferometric fiber-optic gyroscope in closed-loop configuration. The gyroscope utilizes all-fiber components including piezoelectric phase modulator and unexpensive single-mode fiber, which are commonly used only for open-loop configurations. To realize closed-loop operation, special modulation scheme based on fully harmonic signal was develeped, which yields linear output within wide dynamic range. This type of modulation requires high level of synchronization achieved by using a field-programmable gate array module. The gyroscope utilizes powerful broadband fiber source, polarizer and Lyot depolarizer which ensure good reciprocity of whole architecture. The parameters of the sensor, obtained by measurement, are even comparable to some sensors using PM fiber, which is much more expensive.
