Robot Pseudo-Growth Control Across Power-Off and Reboot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robots that continue to count time during power-off periods result in unnatural pseudo-growth upon restart, causing user discomfort.
Innovation Solution
A control device that updates pseudo-days elapsed after device activation under certain conditions, stores this data at power-off, and restarts the update from the stored value upon reboot, ensuring a natural pseudo-growth progression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the built-in clock continues counting during power-off periods, then the robot maintains continuous growth tracking, but the robot displays unnatural pseudo-growth after restart causing user discomfort
Solution Approach 1:
The system performs preliminary action by storing the pseudo-day count value before power-off occurs. This allows the growth tracking data to be preserved and restored after restart, preventing the unnatural jump in growth that would otherwise occur when the clock continues counting during power-off periods.
2Loss of energy
If the main power supply is turned off for long periods, then energy consumption is reduced, but the robot's growth parameter becomes disconnected from actual operational time
Solution Approach 1:
The system uses itself to solve the problem by utilizing its own stored pseudo-day count value to reset and continue the growth tracking after restart. This self-service mechanism ensures that the growth parameter remains accurate relative to actual operational time without requiring external intervention or continuous power supply.
3Measurement precision
If the clock stops counting during power-off, then growth tracking becomes inaccurate, but continuous counting creates unnatural growth display after restart
Solution Approach 1:
The system implements feedback by using the stored pseudo-day count value to adjust and reset the growth tracking after restart. This feedback mechanism ensures that the growth display remains natural and consistent with user expectations, while maintaining accurate tracking during operational periods.

AI summary
An object is to express a more natural pseudo-growth of a robot even after a power-off period. A control device (100) includes a control section (110) which updates number of pseudo-days elapsed after birth of a device (200), on condition that time elapsed from activation of the device (200) has satisfied a predetermined condition, stores the number of pseudo-days elapsed after the birth and acquired at power off timing of the device (200), in response to power-off of the device (200), and restarts update of the number of pseudo-days elapsed after the birth with the stored number of pseudo-days elapsed after the birth as a starting point, in response to reboot of the device (200).
