Robot Object Posture Correction for Accessible Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot devices struggle to autonomously arrange objects in optimal positions and postures for users, particularly those with disabilities, as they do not consider the surrounding environment or the user's ease of use when placing or handing over objects.
Innovation Solution
A robot device equipped with an environment map, image input unit, target object detection, object position and posture detection, and an object posture correction unit, which learns and retains optimal postures for each environment, allowing for autonomous arrangement and correction of object positions and postures to facilitate user accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If robot devices place objects in empty spaces without considering optimal position or posture, then the robot can complete the task of storing objects, but the objects are not arranged in a comfortable or accessible manner for users
Solution Approach 1:
The robot performs preliminary analysis of the empty space characteristics (size, shape, location) before placing objects. The control unit pre-determines the optimal position and posture within the empty space based on object characteristics and user accessibility requirements, rather than simply placing objects anywhere available.
Solution Approach 2:
The system uses image recognition to detect object positions and postures, then compares them against optimal configurations. The control unit adjusts object placement based on this feedback loop, continuously improving placement quality by considering both space constraints and user accessibility needs.
2Ease of operation
If robot devices hand over objects without considering optimal posture, then the handover task is completed, but the user cannot easily hold or use the object
Solution Approach 1:
The robot determines the optimal handover posture in advance based on object characteristics and user needs. The control unit prepares the object in the correct orientation before the handover action, eliminating the need for post-handover adjustment and saving time.
Solution Approach 2:
The system autonomously determines and executes optimal handover postures without requiring user guidance or correction. The control unit independently analyzes object properties and selects the most suitable handover configuration, making the robot self-sufficient in providing useful handovers.
3Adaptability or versatility
If robot devices use simple object placement without environmental consideration, then the placement process is quick, but the arrangement does not create a comfortable environment for users
Solution Approach 1:
The robot analyzes the specific characteristics of each empty space location (size, shape, proximity to user, surrounding objects) and determines placement strategies tailored to each location's unique properties. Different regions of the environment receive different placement treatments based on their local characteristics.
Solution Approach 2:
The control unit varies placement parameters (position coordinates, object orientation angles, depth within space) based on environmental analysis. The system dynamically adjusts these parameters to optimize both the comfort of the arranged environment and the efficiency of the placement process.
