Abstract
U diplomskom radu opisani su najčešće korišteni sustavi lokomocije i tipovi adhezijskih mehanizama robota penjača. Detaljnije je obrađena tematika adhezijskog mehanizma potiska u kombinaciji s negativnim tlakom. U diplomskom radu je razvijen eksperimentalni postav, proizveden aditivnom tehnologijom, čiji je cilj ispitivanje komercijalno dostupnih cijevnih ventilatora (eng. electric ducted fan, EDF) kao aktuatora za ostvarivanje adhezije potiskom u kombinaciji s negativnim tlakom. Kroz rad se ispituje utjecaj različitih oblika difuzora na silu adhezije te se ispituje mogućnost ostvarivanja kombinirane vertikalne i horizontalne sile prianjanja. Prilikom oblikovanja poprečnog presjeka difuzora korišten je program Ansys Fluent pomoću kojeg su izvedeni zaključci o načinima optimizacije difuzora. Na posljetku rada je odabrana kombinacija difuzora i cijevnog ventilatora koji ostvaruje najveće sile adhezije te je provedeno dulje testiranje na glatkoj podlozi, podlozi s manjim i podlozi s većim granulatom kako bi se ispitao utjecaj površine na sile adhezije.
Abstract (english)
The thesis lists the most used locomotion systems and types of adhesion mechanisms of climbing robots. The topic of the adhesive mechanism of thrust in combination with negative pressure is explained in more detail. The thesis describes an experimental setup, produced by additive technology, which aims to test commercially available electric ducted fans (EDF) as actuators for achieving adhesion by thrust in combination with negative pressure. The paper examines the influence of different forms of shrouds on the adhesion force and examines possibility of achieving a combined vertical and horizontal adhesion force. When designing the shape of the shrouds, the program Ansys Fluent was used, to draw conclusions of shroud shape optimization. At the last part of thesis, a combination of shroud and EDF that achieves the highest adhesion forces was selected . With that combination, longer testing was performed on a smooth surface, surface with smaller and larger granules to examine the surface influence on the adhesion forces.
