Solution Overview
Problem
Autonomous vehicles face impediments in warehouse aisles due to obstacles, which hinder efficient operation and productivity by causing slowed speeds, congestion, and deviations from paths, necessitating a method to effectively mitigate these obstacles.
Innovation Solution
A computing system that receives event signals from autonomous vehicles, determines the presence of obstacles using sensors, and transmits tasks to other vehicles to clear the obstacles, utilizing communication devices and processors to navigate and remove obstacles based on their characteristics.

Engineering Contradiction Analysis
1Productivity
If autonomous vehicles operate in warehouse aisles with fixed storage shelves and limited space, then the vehicles can efficiently traverse paths between rows, but obstacles in the aisles cause significant impediments to vehicle flow and productivity
Solution Approach 1:
The system performs preliminary detection of obstacles using sensors (cameras, LiDAR, depth sensors) before vehicles encounter them. The computing system receives event signals from multiple vehicles, identifies obstacle presence in advance, and proactively assigns clearance tasks to appropriate vehicles, preventing operational disruptions before they occur.
Solution Approach 2:
The computing system acts as an intermediary between obstacle detection and vehicle navigation. It receives sensor data from vehicles, processes obstacle information, determines appropriate clearance tasks, and transmits navigation instructions to vehicles. This intermediary coordination enables efficient obstacle mitigation while maintaining continuous vehicle flow in the constrained aisle environment.
2Productivity
If the computing system monitors multiple vehicles and coordinates obstacle clearance tasks, then overall system productivity improves, but the complexity of the communication and control system increases
Solution Approach 1:
The computing system performs multiple functions: receiving event signals from vehicles, detecting obstacles through sensor data, determining obstacle characteristics, assigning clearance tasks, and monitoring task completion. This multi-functional centralized controller consolidates what would otherwise require complex distributed intelligence across multiple vehicles, reducing overall system complexity while improving coordination efficiency.
3Reliability
If vehicles slow down or deviate from paths to avoid obstacles, then safety is maintained, but operational speed and productivity decrease
Solution Approach 1:
The system designates specific vehicles as obstacle clearance specialists based on their capabilities and current task status. When an obstacle is detected, the computing system assigns clearance tasks to the most suitable vehicle, which then autonomously navigates to the obstacle, clears it using onboard mechanisms, and reports completion. This self-service approach eliminates the need for all vehicles to slow down or deviate, maintaining overall fleet speed while ensuring safe obstacle handling.

AI summary
Disclosed herein are systems and methods for autonomous vehicle operation. A computing system can include a communication device configured to receive a plurality of event signals from at least a first autonomous vehicle that is traversing a path, and a processor in electrical communication with the communication device and configured to determine whether the event signals are indicative of an obstacle in a portion of the path. The communication device can be configured to receive, from at least a second autonomous vehicle, at least one characteristic of the obstacle captured by at least one sensor of the second autonomous vehicle, and transmit, to at least a third autonomous vehicle, at least one task to clear the obstacle from the portion of the path. The processor can be configured to determine, based on the characteristic of the obstacle, the at least one task to be transmitted by the communication device.
