Considerations in Determining Human-Robot Ratio

With the increasing level of system autonomy, the Human-Robot Ratio (HRR) can potentially be increased for more efficient operations. The HRR can be used to inform the plausible team structure in the real-world operations. However the computation of HRR can be inferred from various sources, such as human and mission performances. A small-scale study was conducted to understand how these measurements could be interpreted and used to inform the optimal HRR. The result shows that the proposed HRR derived from the human and mission performance might not be the same, suggesting that various mission-centric and human-centric factors must be considered before an optimal HRR could be derived.
