abstract = {This study advances collective perception in swarm robotics by introducing the Automated Swarm Opinion Diffusion Model (aSODM), which addresses the limitations of the original Swarm Opinion Diffusion Model (SODM). Both aSODM and SODM are evidence accumulation methods based on human-like decision-making processes. While SODM integrates social and personal information similarly to aSODM, its reliance on a manually predetermined social factor parameter limits its adaptability to diverse task difficulties. The Automated Swarm Opinion Diffusion Model eliminates this dependency by introducing an adaptive personal factor parameter, which automatically adjusts the weighting of personal and social information based on the information gathered about the environment. This automated approach improves robustness and reduces the dissemination of erroneous information in the early phases of a task. Comparative simulations against baseline methods (Voter Model and Majority Rule) demonstrate that aSODM enhances efficiency, particularly in tasks with higher difficulty levels. While aSODM outperforms SODM, its automated critical parameter selection makes it particularly well-suited for real-world applications where prior knowledge of the environment and task difficulty is lacking.},

abstract = {We present a human inspired approach to collective decision-making in swarm robotics, leveraging a social drift diffusion model that models the decision making process of group of humans. We adapt its principles to robotic swarms to address collective perception tasks. Our method introduces the social factor parameter that allows direct control over the trade-off between decision speed and accuracy. It enables robotic swarms to reach consensus on environmental characteristics more efficiently, with the possibility to prioritize either speed or accuracy, depending on the task requirements. Experimental simulations across various environmental complexities demonstrate our method\'s superior performance compared to traditional algorithms like the voter model and majority rule. The results highlight the effectiveness of human-inspired decision-making mechanisms in enhancing the capabilities of swarm robotics.},
