AI summary

Autonomously aligning docking bodies is provided. A first-axis surface is identified as a target axis surface corresponding to a desired docking approach vector of a first body to a second body. The first body is maneuvered to align relative to a second-axis surface until a third-axis surface is less than a defined surface detection threshold level. The first body is continued to be maneuvered to align relative to the third-axis surface until the second-axis surface is less than the defined surface detection threshold level. Docking is completed between the first body and the second body in accordance with the desired docking approach vector based on alignment of the first body with the target axis surface.
