Infrastructure That Fortifies: Extended-Reach Tendon Construction by Autonomous Matrix Worm Agents Following Principal Stress Trajectories

This paper presents the extended-reach construction capability of Adaptive Matrix Worm (AMW) agents, focusing on tendon installation along principal stress trajectories across large AME installations. Where Infrastructure That Strengthens covers localised reinforcement, this paper addresses long-span structural tendons that span entire installation segments — analogous to the post-tensioning tendons of prestressed concrete, but installed autonomously by soft robotic agents following computed stress field paths using the Depot-Pull prestress method. The paper draws on soil mechanics, structural theory, and strut-and-tie models as engineering foundations, and establishes that all Fortifies construction missions…
