Navigation of B2 mobile robot in outdoor environment
Hoffmann, David ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
This master’s thesis deals with the navigation of a mobile robot that uses the ROS framework. The aim is to improve the ability of the existing B2 robot to move autonomously outdoors. The theoretical part contains a description of the navigation core, which consists of the move_base library and the packages used for planning. The practical part describe the aws of the existing solution, the design and implementation of changes and the results of subsequent testing in the urban park environment.
Simulation model of mobile robots design for ROS framework
Hoffmann, David ; Hrbáček, Jan (referee) ; Věchet, Stanislav (advisor)
This bachelor thesis deals with possibilities of visualization in ROS framework. This software serves as the operating system for robot control. The work contains a description of the visualization environment and instructions for creating a visualization model. There is also documented the creation of RC buggy visualization model and its testing using the Stage simulator.

Our development area comprises the corner part of building block delimited by streets Brabansko – Malá Dlážka on parcels No. 4382, 4379, 4378, 4380. The place is divided by the river Bečva and by the waterfront road from the historic town centre. Multifunctional building includes public service and housing. The front entry is from the riverside street Brabansko, parking and supply place on the courtyard open to the street Malá Dlážka. First 3 floors serves as a commercial lease place, which can be free divided due to used space structure. 3th – 5th floor are destined for flats 2+kitchen and 3kitchen, 6th – 9th floor flats 4+kitchen. Urbanistic situation: fractionalism of sporadic building, breach of the street lines, absence of the regulative plan, specificity of waterfront. Space solution: Main feature: calm space with pedestrian, the river – impression – change of mood all day, water reflex, the south sun There are two differential points of view: over the river: sensation context of 2 adjoining building – linearity, pacific mass; close view – expression variety of surrounding allows more creative concept. The mass is connected to adjoining building and grows up. The form is inspired by ship, the corner symbolizes keel. The corner tower was cut in 2 directions, cuts are not so expressive over the river, it is apparent from side and close view. The cut features fallacy - disturbance of the vertical lines turns beholder´s head, it seems to be thinner than the prism. Open corner gives view angle from the rear street and there is a entry place with entry to the grand floor, to stairs to 1st and 2nd floor and through the passage way to car lifts and central stairs leading from basement garage through all the residential tower. There is used attractive views – terrace in 2nd floor for offices and large glass surfaces in flats. The facade raster against river matches scale of adjoining building, raster of cut surfaces is denser. It is the second fallacy – softer scale, so the surface seems to be deeper from the front view. Color solution result from water reflex, there are 3 materials of the diverse reflection intensity: glass, safety enamel dark grey glass and aluminum siding of blue metallic reflex. So there are various surface features all day. There is replaced dark glass surfaces by photovoltaic panels in the various solution. The construction combines concrete frame and wall system, both monolithic steel concrete, the basement is from rigid water-proof concrete construction, which results water and earth pressure. Yard facade is plaster and lightweight facade systems on front face – steel jambs clipped on steel concrete flooring plate. Parking for non-residential spaces is provided by vertical independent car lift for 2 cars and 2 standing for disabled, 36 places in sum. 14 parking standing is in the basement for residential, enterable from yard lift.
