Robot Task Management via State Table Validation

The patent introduces a state machine as an intermediary component between multiple tasks and the robot system. This state machine manages task transitions by querying a preset state table to determine valid state transitions, thereby mediating between diverse task requirements and system stability requirements. The state machine acts as a controller that ensures only valid task switches occur, preventing state disorders while allowing cross-process and cross-system task execution.

The patent implements a feedback mechanism where the state machine continuously queries the preset state table to determine whether task transitions are valid. This feedback loop ensures that task execution efficiency is maintained by preventing invalid task switches that would cause state disorders. The state machine receives task execution status information, compares it against predefined valid transitions in the state table, and only allows transitions that maintain system stability, thereby ensuring efficient task execution.

The patent applies preliminary action by pre-defining all valid task transition relationships in a preset state table before the robot system operates. The state machine queries this pre-prepared state table to validate whether a task transition is allowed before actually switching tasks. This preliminary validation prevents invalid task combinations (such as performing navigation during dancing) from occurring, thereby maintaining system reliability while still allowing flexible task transitions according to the predefined valid relationships.
