Robot Sensor Control After Motion to Prevent False Stimuli
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robots covered with exteriors that mimic fur or other materials often falsely detect external stimuli due to displacement or rubbing, leading to unnatural actions.
Innovation Solution
A robot control device that suppresses the detection operations or reduces the detection sensitivity of sensors like touch and microphone sensors for a predetermined time after an action ends to prevent false detections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the robot is covered with an exterior that resembles fur to make it look more like a living being, then the robot's appearance is improved, but false detections of external stimuli occur due to displacement or rubbing of the exterior
Solution Approach 1:
The control device stops the sensor detection operation or reduces detection sensitivity in advance before the exterior displacement or rubbing occurs (i.e., before the action ends), preventing false detections from happening in the first place
Solution Approach 2:
The control device applies a counter-action by stopping or reducing sensor detection sensitivity during the period when false detections are likely to occur, counteracting the harmful effect of exterior displacement or rubbing
2Speed
If the sensor continuously detects external stimuli to ensure responsive behavior, then the robot's responsiveness is improved, but false detections occur during and after actions due to exterior displacement
Solution Approach 1:
The sensor detection operation is performed periodically with intervals: active during actions when real stimuli need to be detected, and stopped or reduced during periods when false detections are likely (after actions end), creating a rhythmic on-off pattern that balances responsiveness and accuracy

AI summary
Disclosed is a robot control device including one or more processors configured to: determine whether an action performed by a robot including a sensor that detects an external stimulus has ended; and, in response to an end of the action, cause the sensor to stop a detection operation or cause the sensor to reduce a detection sensitivity for a predetermined time from the end of the action.
