Solution Overview

Problem

Current methods for multiple target interception by autonomous agents face challenges in maximizing the number of targets intercepted while avoiding collisions, especially in dynamic and uncertain environments, where traditional solutions require complex decomposition and are not scalable or efficient.

Innovation Solution

A method and system for operating a swarm of autonomous vehicles that identify targets and obstacles, calculate trajectories to maximize the probability of interception and collision avoidance, using deterministic and stochastic schemes to ensure efficient target acquisition and motion planning without separate task allocation or trajectory planning, allowing for linear computational complexity and robustness to uncertainties.

1Productivity

If traditional decomposition methods are used for multiple target interception, then task allocation can be performed, but computational complexity increases and scalability decreases

Engineering Contradiction:
Improvetarget interception efficiencyVSAvoidcomputational complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines task allocation and trajectory planning into a single unified optimization problem. Instead of decomposing the interception task into separate allocation and execution phases, the method formulates a joint optimization that simultaneously determines which agent intercepts which target and what trajectory each agent should follow, thereby reducing computational complexity while maintaining interception effectiveness.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the operational area into Voronoi regions based on agent positions, allowing each agent to independently optimize its trajectory within its region. This spatial segmentation enables parallel computation and reduces the overall computational burden while ensuring comprehensive coverage of all targets.

Inventive Principle:
Principle #1Segmentation

2Reliability

If complex trajectory planning is implemented to maximize interception probability, then target acquisition improves, but computational time increases

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent performs preliminary computation of Voronoi regions and initial trajectory directions before the actual interception process. By pre-establishing the spatial partitioning and initial guidance vectors, the system reduces real-time computational requirements while maintaining high interception probability through optimized trajectory generation within the pre-defined framework.

Inventive Principle:

3Reliability

If deterministic schemes are used for known scenarios, then interception is guaranteed, but adaptability to uncertain environments decreases

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic scheme that adapts to environmental uncertainty by continuously updating Voronoi regions and re-optimizing trajectories as agent positions and target locations change. This dynamic recalibration allows the system to maintain deterministic guarantees in known scenarios while adapting to new information and uncertainties in dynamic environments, achieving both reliability and versatility.

Inventive Principle:
