Nursing-Care Robot Control for Adaptive Elimination Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elimination treatments, such as changing diapers, are difficult and delicate nursing care tasks that burden caregivers and can cause discomfort for care receivers.
Innovation Solution
A nursing-care robot system equipped with a control device that includes a storage part, state variable acquisition part, and instruction generation part to execute elimination treatments based on acquired state variables, such as positional data, body type, and posture of the care receiver, allowing the robot to perform these tasks autonomously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If elimination treatment is performed manually by caregivers, then the treatment can be adjusted to individual needs, but caregiver burden increases and treatment consistency deteriorates
Solution Approach 1:
The nursing-care robot performs elimination treatment autonomously by acquiring state variables (positional data, body type, posture) and automatically generating behavior instructions based on stored behavior programs, enabling the system to serve itself without continuous human intervention while maintaining consistent treatment quality
Solution Approach 2:
The robot acquires real-time state variables regarding the care receiver's position, body type, and posture, then uses this feedback to adjust elimination treatment instructions dynamically, ensuring consistent and appropriate treatment while reducing caregiver burden
2Productivity
If elimination treatment is automated with fixed programs, then productivity increases, but adaptability to individual care receivers deteriorates
Solution Approach 1:
The elimination treatment program transitions from static to dynamic by incorporating real-time state variables (positional data, body type, posture) that allow the robot to adapt behavior instructions to each care receiver's individual characteristics while maintaining automated efficiency
Solution Approach 2:
The system changes operational parameters based on acquired state variables, adjusting elimination treatment instructions according to individual care receiver attributes such as body type and posture, thereby achieving both productivity and adaptability
3Measurement precision
If state variables are acquired and processed, then treatment accuracy improves, but device complexity increases
Solution Approach 1:
The control device integrates multiple functions into a unified system: acquiring state variables, storing behavior programs, processing data, and generating behavior instructions, thereby managing complexity through functional integration while maintaining high measurement precision

AI summary
A nursing-care robot control device is a nursing-care robot control device controlling a nursing-care robot performing a nursing-care behavior, including: a storage part storing a behavior program; a state variable acquisition part acquiring a state variable corresponding to a state of a care receiver; and an instruction generation part generating a behavior instruction to the nursing-care robot from the behavior program and the state variable, wherein the behavior program includes an elimination treatment program for the nursing-care robot to perform an elimination treatment on the care receiver, the instruction generation part generates an elimination treatment instruction corresponding to the care receiver from the elimination treatment program as the behavior instruction, and the state variable includes a first state variable, which is a state variable used for adjusting the elimination treatment instruction, corresponding to positional data, a body type, and a posture of the care receiver.
