Robot Object Transport Using Height-Limited Paths to Reduce Fall Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot systems face challenges in preventing damage to target objects during movement due to potential falls.
Innovation Solution
A robot system that sets a height restriction using a reference plane and calculates a path for object movement based on this restriction to minimize the risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the robot lifts the target object to a higher position during movement, then the movement path becomes more flexible and obstacles can be avoided, but the risk of damage increases if the object falls
Solution Approach 1:
The system performs preliminary analysis of the movement environment to identify obstacles and predetermined safe zones before generating the movement path. By pre-planning the path to avoid obstacles and select safe zones for potential placement, the system enables flexible movement while pre-establishing safety measures to prevent or mitigate falling damage.
2Productivity
If the robot moves the target object quickly to the destination, then productivity increases, but the stability of the object during movement decreases
Solution Approach 1:
The movement path is dynamically adjusted based on real-time conditions and object characteristics. The system generates paths that adapt to the specific task requirements, balancing speed and stability by selecting appropriate path characteristics for different movement phases and object types.
3Loss of time
If the robot follows a direct path to the movement destination, then the movement time is reduced, but the object may pass through unstable or harmful areas
Solution Approach 1:
The system performs preliminary environmental analysis to identify obstacles, unstable areas, and safe zones before path generation. This pre-planning enables the robot to select optimal paths that avoid harmful areas while maintaining efficient movement time.

AI summary
A robot system is configured to set a restriction on a range of a height to which a target object is lifted using a reference plane as a reference and configured to calculate a path along which the target object is moved to a movement destination based on the set restriction.
