Autonomous Robot Behavior Control Based on Battery Charge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robot technologies have not advanced to the point where they can autonomously select human-like or animal-like actions based on their internal state and external environment, limiting their ability to provide empathy and interaction with humans.
Innovation Solution
An autonomously acting robot equipped with an operation control unit, a drive mechanism, and a remaining battery charge monitoring unit that selects motions and adjusts behavioral characteristics based on battery charge levels, allowing it to respond to events and change modes between normal and power-saving operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the robot operates with high activity amount, then it can provide better interaction and empathy, but the battery charge depletes faster
Solution Approach 1:
The robot dynamically adjusts its behavioral characteristics and activity level based on real-time battery charge status. When charge is sufficient, the robot exhibits more active, empathetic behaviors. When charge is low, it automatically reduces activity to conserve energy, creating a living-creature-like response to energy states.
Solution Approach 2:
The robot continuously monitors its battery charge level and uses this feedback to modulate its behavior. This closed-loop control allows the robot to adapt its interaction style, movement, and responsiveness based on available energy, ensuring sustained operation while maintaining meaningful interaction.
2Adaptability or versatility
If the robot autonomously selects actions based on internal state, then empathy and companionship increase, but device complexity increases
Solution Approach 1:
The robot changes its operational parameters (activity level, interaction intensity, movement frequency) based on internal state parameters (battery charge). This parameter-based control enables autonomous adaptation without requiring complex decision-making architectures, achieving lifelike behavior through parameter modulation rather than complex reasoning.
3Duration of action of moving object
If the robot restricts power supply to save energy, then battery life extends, but operational capability decreases
Solution Approach 1:
The robot applies partial power restriction by selectively reducing non-essential functions while maintaining core operational capabilities. Instead of uniformly limiting all operations, it preserves critical interaction and safety functions while reducing auxiliary activities, thereby extending battery life without completely sacrificing operational usefulness.

AI summary
A robot includes an operation control unit that selects a motion of the robot, a drive mechanism that executes a motion selected by the operation control unit, and a remaining battery charge monitoring unit that monitors a remaining charge of a rechargeable battery. Behavioral characteristics of the robot change in accordance with the remaining battery charge. For example, a motion with a small processing load is selected at a probability that is higher the smaller the remaining battery charge. Referring to consumption plan data that define a power consumption pace of the rechargeable battery, the behavioral characteristics of the robot may be caused to change in accordance with a difference between the remaining battery charge scheduled in the consumption plan data and the actual remaining battery charge.
