Dynamic Sensor Discovery for Autonomous Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autonomous vehicles are limited by the static definition of external sensors, which restricts their ability to take variable routes or navigate to unplanned destinations, as they can only utilize sensors that are predefined and known.
Innovation Solution
A system that enables dynamic sensor discovery, where autonomous devices can request and access sensor information from a data server, allowing them to use on-board and external sensors along planned routes, including those outside their detection range, by registering and selecting relevant sensors based on location and destination, enabling navigation without human input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external sensors are statically defined in conventional autonomous vehicles, then the system structure is simple and reliable, but the navigation flexibility and ability to take variable routes are reduced
Solution Approach 1:
The patent implements dynamic sensor discovery where the autonomous vehicle can identify and utilize sensors along its planned route in real-time, rather than relying on a static pre-defined sensor list. This allows the vehicle to adapt to variable routes and unplanned destinations by dynamically querying and accessing sensor data from the environment, thereby improving navigation flexibility without permanently increasing system complexity.
2Adaptability or versatility
If external sensors are statically defined, then the system is reliable and easy to operate, but the ability to navigate to unplanned destinations is limited
Solution Approach 1:
The patent introduces a sensor discovery system that acts as an intermediary between the autonomous vehicle and external sensors. This mediator enables the vehicle to dynamically discover and access sensors along its route without requiring complex manual configuration or programming, thereby maintaining ease of operation while significantly improving the ability to navigate to unplanned destinations.
3Productivity
If the autonomous vehicle uses only predefined sensors, then the device complexity is low, but the navigation capability to unplanned destinations is reduced
Solution Approach 1:
The patent implements preliminary sensor discovery where the autonomous vehicle queries for available sensors along its planned route before executing the navigation. This preliminary action allows the vehicle to identify and prepare to use relevant sensors in advance, improving navigation capability to unplanned destinations while managing device complexity by performing the discovery process automatically as part of the navigation planning workflow.

AI summary
Systems, apparatuses, and methods for enabling sensor discovery in autonomous devices herein. An example system for enabling dynamic sensor discovery including a client that includes an autonomous device. The autonomous device is capable of navigating from a current location to a destination location using sensor data. The client provides a request for sensor information for sensors along a planned route and receives respective sensor information for each of a set of selected sensors selected by a data server based on the request. The client subscribes to a data feed of a sensor of the set of selected sensors along the planned route based on sensor information corresponding to the sensor and client analyzes the data feed to determine whether to proceed with the planned route.
