Pneumobile car-body design for robotic fabrication
Vevera, Tomáš ; Nevřela, Petr (referee) ; Škaroupka, David (advisor)
This thesis solves design of the pneumobile bodywork designated for robotic manufacturing using curved folding method. The thesis evaluates possibilities of this technology and issue of specific behaviour of CCF geometries. With intention to simplify and speedup the proces of designing, the suggestion of software tool for CCF geometry simulation is proposed. Obtained pieces of knowledge are being used in creating the prototype of designed solution using curved folding.

Styling of the passenger car Proton Prevé
Burjeta, Josef ; Karásek, David (referee) ; Škaroupka, David (advisor)
The thesis is focused on styling a real passenger car Proton Prevé with regard to the quality of surface modelling using computer software Autodesk Alias. The stylistic adjustments were made on basis of the background research and poll focused on the target group. Selected body parts have been modified according to the desired sport character of the car and the current vehicle’s appearance. The result of the work is a surface model, which was created using A-Class modelling methods under the direction of Evektor company. The benefit of the thesis is facelift of an existing car with consideration of the current market situation and customer requirements.

Supportless 3D print by 6-axis robotic arm
Krejčiřík, Petr ; Horák, Zdeněk (referee) ; Škaroupka, David (advisor)
This diploma thesis deals with the solution 3D printing by KUKA robotic arm without realization of supporting structures. The 6-axis KUKA KR 60HA robotic arm allows adjusting 3D printing strategies compared to classical 3D printing concept. The first part of the diploma thesis is about the identification of the current state of knowledge, especially the state of the experimental device for the robotic 3D print. To improve quality of the printed is necessary to modify the printing head and develop the suitable calibration principle. Special printing strategies were designed to rearch the 3D printing overhead volumes without creating support structure. A special alghoritm in the Grasshopper evnironment was developed for generating 3D print trajectory on the body surface. For the quality improvement it is necessary to optimize the process parameters. The final step is experimental 3D printing with the evaluation of surface dimensions, geometric precision and layer coherence in various printing strategies.

Design of the hammer set
Král, Ondřej ; Haltof, Vladimír (referee) ; Škaroupka, David (advisor)
This bachelor’s thesis is focused on the design of a product family of hammers by the means of generative design. The core of this thesis is the creation of an algorithm which will generate hammers of unified visual style, but varying properties based on input parameters. It is necessary that these hammers are in shape, ergonomics and dimensions adequate to preferences of the target group of professional workers and that they are producible in series and from commonly used materials. The output is a set of three hammers with different mass and dimensional properties.

Design of the parametric orthosis for upper limb
Kosová, Barbora ; Jelenčík, Branislav (referee) ; Škaroupka, David (advisor)
This thesis deals with the design and manufacturing of custom-made immobilization orthosis for the upper limb. Emphasis is put on the digitization of the approach and integration of additive manufacturing in the workflow of splint production. The solution proposes automatic model construction based on a 3D scan. Such a model is further parametrized in order to provide splinting practitioners with customization abilities. Particular attention is paid to the changes of limb volume due to swell, where the use of auxetic structures is suggested.

Equipment for the dissolution of 3D printed support material
Vodehnal, Michal ; Škaroupka, David (referee) ; Paloušek, David (advisor)
The aim of this bachelor thesis is to produce a design of an automatic device that washes away and dissolves supports used by 3D printing machine Dimension SST 1200. The thesis contains chapters on a current state of knowledge of the device, its conceptual designs as well as a final engineering design, which is made of weldment and bought components. The proposed device enables the dissolution of the supports in a sodium hydroxide solution and their final washing in a secondary tank. The design also has protective electronic elements and a system for holding a basket. Technical documentation of the device is included in the thesis.

Design of the portable veterinary X-ray machine
Kalenský, Ondřej ; Surman, Martin (referee) ; Škaroupka, David (advisor)
This diploma thesis is focused on the design of a product family of portable veterinary x-ray generators. The thesis deals with the possibilities of using parameterization when designing products which are part of a product series. The main body of the thesis lies in the design of a parametric script which generates variations of portable veterinary x-ray generators depending on the size and position of the inner components. The outer surfaces are defined by algorithms from the input parameters. It is possible to alter the individual attributes (e.g. the progresion of curves, the dimensions of component parts and the proportions between the individual parts). The output from the parametric script is three size-variations of the product.
