Robot Task Switching Control Using End-Condition Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial robots are limited in their ability to adapt and switch tasks based on situational changes, as they primarily perform preset operations at predetermined positions without the capability to alter their tasks or switch depending on the situation.
Innovation Solution
A robot control apparatus and method that includes a determination unit to assess end conditions of tasks and a switching unit to transition to the next task when the end conditions are met, allowing for dynamic task switching based on success or failure criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If robots perform preset operations based on predetermined programs, then operational reliability is improved, but task adaptability deteriorates
Solution Approach 1:
The patent implements dynamic task switching by enabling robots to transition from static preset operations to adaptive task execution based on real-time situation assessment. The determination unit continuously evaluates whether task end conditions are met, and the switching unit dynamically transitions to alternative tasks when needed, making the robot's operational mode flexible rather than fixed.
Solution Approach 2:
The patent employs feedback mechanisms where the determination unit monitors task execution status and provides information to the switching unit. This closed-loop feedback enables the robot to assess whether preset operations have achieved their objectives and to switch tasks accordingly, bridging the gap between reliable preset execution and adaptive task switching.
2Stability of the object's composition
If robots execute predetermined work at preset positions, then operational stability is improved, but task switching capability deteriorates
Solution Approach 1:
The patent segments the robot's control system into distinct functional units: a determination unit for assessing task completion, a switching unit for task transitions, and execution units for specific operations. This segmentation allows each component to specialize in its function while working together, maintaining operational stability through structured organization while enabling task switching through the dedicated switching unit.
Solution Approach 2:
The switching unit acts as an intermediary between the stable preset operation system and the adaptive task selection system. It receives assessment information from the determination unit and translates it into appropriate task transitions, mediating between the need for stable execution and the need for flexible task switching.
3Ease of operation
If robots perform preset operations without determination, then operational simplicity is improved, but task optimization deteriorates
Solution Approach 1:
The patent implements self-service functionality where the robot autonomously determines whether task end conditions are met and automatically switches tasks without human intervention. The determination unit and switching unit work together to enable the robot to self-assess and self-adjust its task execution, maintaining operational simplicity from the user's perspective while achieving task optimization internally.

AI summary
There is provided a robot control apparatus including a determination unit configured to determine whether or not an end condition of a task is satisfied when a robot performs the task, and a switching unit configured to perform switching to a next task corresponding to the end condition in a case where the end condition is satisfied. With this configuration, it is possible to optimally switch tasks of the robot depending on the situation.
