Solution Overview
Problem
Existing robotic systems powered by batteries require users to manually calculate and store power consumption data for each operation, which is time-consuming and effort-intensive, and may lead to battery depletion during operation.
Innovation Solution
A control device that automatically determines the upper-limit number of times a robot can execute operations before recharging by repeatedly testing the battery's output voltage and storing this information, allowing the robot to execute operations within a predetermined threshold, thereby managing battery charge without user effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot stores power consumption information for each operation to manage battery charge, then battery management capability is improved, but user time and effort for calculating and storing data increases
Solution Approach 1:
The control device automatically acquires power consumption information from the database and calculates the upper-limit number of times without requiring user intervention. The system serves itself by autonomously managing battery charge assessment, eliminating the need for users to manually calculate and store power consumption data.
Solution Approach 2:
The patent replaces manual calculation and data storage operations with an automated control device that queries the database and performs calculations electronically. This substitution of manual mechanical operations with automated electronic processing resolves the contradiction between improved battery management and reduced user time investment.
2Device complexity
If the robot operates without automatic battery management, then device complexity is reduced, but the robot may stop due to battery depletion
Solution Approach 1:
The control device continuously monitors battery charge levels and compares them against the threshold value. When the battery charge falls below the threshold, the system provides feedback by notifying the user to recharge, enabling the robot to operate reliably without complex manual intervention while preventing battery depletion.
Solution Approach 2:
The system performs preliminary assessment of battery charge levels before operation begins and continuously during operation. By proactively monitoring and comparing battery charge against the threshold, the system prevents battery depletion before it occurs, ensuring continuous operation without requiring complex emergency management systems.
3Speed
If the robot uses fixed power consumption data, then calculation speed is improved, but adaptability to changing operation content deteriorates
Solution Approach 1:
The upper-limit number of times is not fixed but dynamically determined based on the specific operation content and corresponding power consumption data from the database. When operation content changes, the control device recalculates the upper-limit number of times using updated power consumption information, maintaining both calculation efficiency and adaptability to changing conditions.
Solution Approach 2:
The system changes the parameter of power consumption data based on the specific operation being performed. By querying the database for operation-specific power consumption values and using these to calculate the upper-limit number of times, the system adapts to different operation contents while maintaining fast calculation through automated parameter retrieval and computation.

AI summary
A robotic system includes a robot driven using a battery as a power supply source, and a control device configured to control the robot. The control device executes a setting process of making the robot repeatedly execute a first operation from when the battery is fully charged to when an output voltage of the battery becomes not higher than a predetermined threshold value, and setting a number of times the robot executes the first operation in a range in which the output voltage of the battery is higher than the threshold value as a first upper-limit number of times which is an upper limit of a number of times the robot can be made to execute the first operation in a period from when the battery is fully charged to when the battery is recharged.
