Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robotic systems lack the ability to plan actions based on the varying values of peripheral objects, leading to potential damage or improper handling of valuable items.
Innovation Solution
A control device equipped with a value estimation unit to assess the value of objects using sensor data and an action planning unit to plan movements, routes, postures, and handling methods accordingly, ensuring careful handling of valuable objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot plans actions without considering object values, then the control system is simple and fast, but valuable objects may be damaged or improperly handled
Solution Approach 1:
The value estimation unit performs preliminary assessment of object values before the action planning unit generates movement routes or handling actions. This preliminary valuation enables the control system to prioritize safety measures for high-value objects, resolving the contradiction by preparing safety information in advance rather than adding complex real-time decision-making structures
Solution Approach 2:
The value estimation unit acts as an intermediary component between sensor data and action planning. It transforms raw sensor data into meaningful object value assessments that guide the action planning unit, enabling reliable object protection without requiring the entire control system to become fundamentally more complex
2Reliability
If the robot maintains distance from all objects, then object damage risk is reduced, but the robot's mobility and task completion efficiency decrease
Solution Approach 1:
The action planning unit applies different safety margins and protection levels to different objects based on their estimated values. High-value objects receive larger safety buffers and more cautious handling, while low-value objects allow closer approach and more aggressive manipulation. This local differentiation resolves the contradiction by providing object-specific protection rather than uniform distance maintenance
Solution Approach 2:
The control system dynamically adjusts movement parameters such as speed, acceleration, and positioning precision based on the value of nearby objects. When approaching high-value objects, the system reduces speed and increases positioning accuracy; for low-value objects, normal operating parameters are maintained. This parameter adaptation enables both protection and productivity
3Measurement precision
If the robot uses complex sensor data processing to accurately estimate object values, then handling accuracy improves, but computation time and energy consumption increase
Solution Approach 1:
The value estimation unit employs a hierarchical processing approach where basic object detection and coarse valuation occur quickly using simplified sensor data, while more precise valuation is performed only when needed for high-value objects or critical decisions. This partial application of complex processing resolves the contradiction by avoiding full computation in all scenarios
Solution Approach 2:
The system uses the robot's own sensor data and pre-stored object information to autonomously estimate values without requiring external verification or complex multi-source data fusion in real-time. This self-service approach enables accurate enough valuation for practical purposes while minimizing computation time and energy consumption
