Robot Task Completion Determination Using State Propositions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining task completion by robots are complex and require individual schemes for each task, relying on sensor outputs, which complicates the process of accurately assessing whether a robot has completed a task.
Innovation Solution
A determination device and method that use propositions representing the current and completion states of a task, detected by sensors, to determine task completion based on the completion of an operation sequence or a predetermined time elapsed since the task's start, allowing for standardized completion assessment across various tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a complicated process based on sensor output is used for task completion determination, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the task completion determination process into distinct phases: operation sequence completion detection and time-based determination. By dividing the determination logic into separate pathways (sequence-based vs. time-based), the system achieves accurate completion detection without requiring a single complex determination process for all tasks.
Solution Approach 2:
The patent performs preliminary actions by detecting operation sequence completion and time elapse before final task completion determination. The system monitors intermediate states (operation sequence progress and elapsed time) in advance, allowing it to determine task completion based on pre-established criteria without requiring complex real-time analysis.
2Measurement precision
If individual completion determination schemes are prepared for each task, then measurement precision is improved, but adaptability decreases
Solution Approach 1:
The patent creates a universal task completion determination system that can handle multiple different tasks through a single standardized framework. By using general concepts (operation sequences, time measurement, proposition comparison) that apply across various task types, the system achieves both accurate completion determination and broad adaptability without requiring task-specific schemes.
Solution Approach 2:
The patent introduces intermediary elements (standardized propositions representing task states, operation sequence models, and time measurement mechanisms) that mediate between different task types and the completion determination logic. These intermediaries allow the system to translate diverse task requirements into a common determination framework, enabling both precision and versatility.

AI summary
A determination device 1X mainly includes a proposition determination means 18X. The proposition determination means 18X performs a completion determination of a task based on a first proposition representing a current state of the task and a second proposition representing a completion state of the task, in which the first proposition and the second proposition are detected by a sensor, when an operation sequence concerning the task has completed or when a predetermined time length has lapsed from a start of the task.
