Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional robotic systems lack the ability to implement feature-specific actions based on detected entities, objects, or structures in their environment, leading to inefficient navigation and potential safety issues due to a lack of customization in responding to different types of movers, such as humans or other robots.
Innovation Solution
A method that utilizes a combination of sensors, including image and lidar sensors, to detect and classify features, allowing the robot to fuse data and react appropriately based on classifications, such as communicating with or adjusting navigation behavior around movers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional robotic systems use generic navigation without feature-specific actions, then device complexity is reduced, but navigation safety and efficiency deteriorate
Solution Approach 1:
The system segments the environment into distinct feature types (e.g., humans, animals, obstacles, structures) and applies specific navigation actions to each segment. This allows the robot to handle different features with specialized routines, improving navigation safety while managing complexity through modular organization of detection and response mechanisms.
Solution Approach 2:
The system changes navigation parameters dynamically based on detected feature types. When different feature classifications are detected, the robot adjusts its navigation behavior parameters (speed, distance, avoidance maneuvers) accordingly. This enables adaptive navigation that responds to environmental context without requiring complete system redesign.
2Measurement precision
If the robot implements feature-specific actions with multiple sensor types, then navigation accuracy is improved, but computational load increases
Solution Approach 1:
The computational system segments feature detection into specialized modules, each handling specific feature types or sensor data types. This modular approach allows parallel processing of different sensor inputs and feature classifications, improving detection accuracy while optimizing computational resource utilization through dedicated processing pathways.
Solution Approach 2:
The system introduces an intermediary classification layer that processes raw sensor data from multiple sources before executing navigation actions. This intermediary step consolidates and interprets multi-sensor information, enabling accurate feature identification while reducing the computational burden on the navigation decision-making process by pre-processing and structuring sensor inputs.
3Reliability
If the robot uses multiple sensors to detect features and movers, then detection reliability is improved, but device complexity increases
Solution Approach 1:
The system merges data from multiple sensor types (image sensors, lidar, other sensors) into a unified feature detection framework. By combining sensor inputs and processing them through integrated algorithms, the system achieves reliable feature and mover detection while managing hardware complexity through coordinated sensor operation and data fusion rather than independent processing of each sensor.
Solution Approach 2:
The sensor system is designed with multi-functionality where sensors serve multiple purposes. For example, image sensors and lidar both contribute to detecting features, movers, and environmental structures. This universal approach allows the same hardware to perform multiple detection functions, improving detection reliability without proportionally increasing device complexity.

AI summary
Systems and methods are described for reacting to a feature in an environment of a robot based on a classification of the feature. A system can detect the feature in the environment using a first sensor on the robot. For example, the system can detect the feature using a feature detection system based on sensor data from a camera. The system can detect a mover in the environment using a second sensor on the robot. For example, the system can detect the mover using a mover detection system based on sensor data from a lidar sensor. The system can fuse the data from detecting the feature and detecting the mover to produce fused data. The system can classify the feature based on the fused data and react to the feature based on classifying the feature.
