## Summary

This paper proposes a hybrid discrete-continuous multi-objective bilevel framework for the structure-actuation co-design of all-electric heavy-duty robotic manipulators: the upper level optimizes geometry and actuation topology, while the lower level searches for feasible configurations of motors, gearboxes, and screws for each joint. A system-level coordinator selects actuator packages based on hardware mass, co-design cost, and loss-aware supply energy, and feeds the resulting actuator masses back into the robot model until mass consistency is reached.
