20.500.12556/DKUM-86548 Audio-visual effects of a collaborative robot on worker efficiency Collaborative workplaces are increasingly used in production systems. The possibility of direct collaboration between robots and humans brings many advantages, as it allows the simultaneous use of human and robotic strengths. However, collaboration between a collaborative robot and a human raises concerns about the safety of the interaction, the impact of the robot on human health, human efficiency, etc. Additionally, research is unexplored in the field of the collaborative robot’s audio-visual effects on the worker’s efficiency. Our study results contribute to the field of studying collaborative robots’ audio-visual effects on the worker’s behavior. In this research, we analyze the effect of the changing motion parameters of the collaborative robot (speed and acceleration) on the efficiency of the worker and, consequently, on the production process. Based on the experimental results, we were able to confirm the impact of robot speed and acceleration on the worker’s efficiency in terms of assembly time. We also concluded that the sound level and presence of a visual barrier between the worker and robot by themselves have no effect on the worker’s efficiency. The experimental part of the paper clearly identifies the impact of visualization on work efficiency. According to the results, the robot’s audio-visual effects play a key role in achieving high efficiency and, consequently, justifying the implementation of a collaborative workplace. collaborative robot worker efficiency motion parameters visual contact sound human-robot symmetry repeated measures ANOVA kolaborativni roboti delovna uspešnost parametri gibanja vizualni stik zvok simetrija človek-robot ponavljajoče se meritve ANOVA true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/ Članek v reviji 2023-12-11 09:46:11 2023-12-11 09:49:32 2024-04-11 07:38:29 0000-00-00 00:00:00 2023 0 0 19 str. iss. 10, [article no.] 1907 Vol. 15 Oct. 2023 0000-00-00 Zaloznikova Objavljeno apc 2023-09-08 2023-10-09 2023-10-12 007.52:658.562 170966275 10.3390/sym15101907 2073-8994 symmetry-15-01907.pdf symmetry-15-01907.pdf 1 754DCEA391B076E053B67AE97A2FDFC0 9fe7fd97bd9e77d1b289d223552011f2099ae77a4bcda4629fb6e2505c078917 dc4c1895-9801-11ee-a2d0-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174794 https://www.mdpi.com/2073-8994/15/10/1907 0 eda245bc-9801-11ee-a2d0-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174795 Fakulteta za strojništvo 0 0 0
