Opis: The auxetic cellular structures are one of the most promising metamaterials for vibration damping and crash absorption applications. Therefore, their use in the bicycle handlebar grip was studied in this work. A preliminary computational design study was performed using various auxetic and non-auxetic geometries under four load cases, which can typically appear. The most representative geometries were then selected and fabricated using additive manufacturing. These geometries were then experimentally tested to validate the discrete and homogenised computational models. The homogenised computational model was then used to analyse the biomechanical behaviour of the handlebar grip. It was observed that handle grip made from auxetic cellular metamaterials reduce the high contact pressures, provide similar stability and hereby improve the handlebar ergonomics.

Opis: Dandanes si le s težavo predstavljamo industrijo brez robotov. Uporabljajo se za skoraj vsa opravila. Najkompleksnejši element robota je po navadi prav prijemalo, ki je zadolženo za opravljanje specifične naloge. V diplomski nalogi sem na dejanskem primeru opisal razvoj in nastajanje prijemala za industrijsko robotsko roko. V prvem delu je na kratko predstavljeno nekaj o industrijskih robotih ter robotskih prijemalih. V drugem delu pa sem se posvetil razvoju prijemala, od načrtovanja pa vse do razdelave. Opravil sem tudi trdnostne preračune za potrebne dele. Celotni postopek razvoja sem poskušal jasno prikazati tudi s pomočjo slik.
Ključne besede: robotska celica, robotska roka, robotsko prijemalo, vakuumski prijem, linearni mehanski prijem in baterijska celica.
