Analysis of Safe Ultrawideband Human-Robot Communication in Automated Collaborative Warehouse
This research addresses the problem of ensuring safe human-robot communication in collaborative warehouse environments to prevent collisions, which is a domain-specific safety concern.
This paper analyzes ultrawideband Gaussian signal propagation in an automated collaborative warehouse to prevent human-robot collisions. It calculates path loss profiles for various scenarios and antenna polarizations, and proposes optimal antenna positions based on these simulations.
The paper presents the propagation analysis of ultrawideband Gaussian signal in an automated collaborative warehouse environment where human and robots communicate to ensure that mutual collisions do not occur. The warehouse racks are principally modeled as clusters of metallic (PEC) parallelepipeds, with dimensions chosen to approximate the realistic warehouse. The signal propagation is analyzed using a ray tracing software, with the goal to calculate the path loss profile for different representative scenarios and antenna polarizations. The influence of the rack surface roughness onto propagation is also analyzed. The guidelines for optimum antenna positions on humans and robots for safe communication are proposed according to the simulations results.
