Abstract

This research aimed to investigate the specific effect of the slant shape on the perceived safety related to UGV Robots. Additionally, it investigates possible differences between the evaluation of those robot shapes considering different nationalities (Japanese and Brazilian), and different types of media used for the experiment (PC Screen and VR Headset). In the investigation, 4 different stimuli were tested and evaluated by 75 participants, 30 Brazilians in the experiment with PC Screen, 22 other Brazilians in the experiment with VR Headset, and 22 Japanese in the experiment with VR Headset. The effect of the slant shape was defined based on two components of Perceived Safety (Sensitivity and Magnitude), as well as the comparisons between experimental groups. The study showed that slant has a positive effect on Perceived Safety for robots that has slant in the front or both sides.
