Robot Role Switching for Workload Balance

The patent uses wake-up word changes as a form of identity differentiation. When a robot's workload exceeds a threshold, it exchanges identity information (including wake-up words) with another robot of the same model, effectively changing its operational identity while maintaining physical appearance. This resolves the contradiction by allowing visual uniformity for manufacturing efficiency while introducing functional differentiation through variable wake-up words to prevent user confusion.

The patent implements dynamic role assignment where robots can exchange tasks and identity information based on real-time workload conditions. The system continuously monitors usage days and task completion status, and automatically triggers role exchanges when imbalance is detected. This dynamic adjustment mechanism enables the same hardware design to adaptively balance workload, resolving the contradiction between manufacturing simplicity and productivity optimization.

The patent creates a universal role-exchange protocol that can be implemented across all robots of the same model without requiring hardware modifications. The identity information package (including wake-up words, task assignments, and usage data) serves as a multi-functional data structure that enables both user-facing personalization and backend workload management. This universal approach achieves improved user experience and workload balance while minimizing system complexity through software-based solutions.
