Optimizing Material Cart Path Planning with Enhanced RRT
In intelligent manufacturing and automated warehousing systems, efficient path planning for material carts is crucial. This study addresses the limitations of the original Rapidly-exploring Random Tree (RRT) algorithm, such as strong path randomness, low search efficiency, and poor path smoothness. We propose an enhanced RRT algorithm incorporating target-biased sampling, heuristic node selection, and cubic B-spline smoothing techniques, demonstrating significant improvements in performance across diverse complex environments.
Quantifiable Impact for Your Operations

The Challenge: RRT Limitations in Logistics
Traditional material cart path planning struggles with dynamic environments and complex operational needs. While the Rapidly-exploring Random Tree (RRT) algorithm offers excellent spatial search capabilities for robotics, its inherent limitations hinder its effectiveness for high-precision, high-efficiency material handling:
- Strong Path Randomness: Uniform random sampling leads to many invalid points and low search efficiency, especially far from the target.
- Low Search Efficiency & Slow Convergence: The algorithm's broad, undirected exploration results in substantial computational overhead.
- Poor Path Smoothness: Without considering kinematic constraints, generated paths are often tortuous and difficult for actual vehicles to execute directly.

Improved RRT Algorithm: Step-by-Step Process
To overcome the limitations of the original RRT, our enhanced algorithm integrates three core improvements: target-biased sampling, heuristic node selection, and cubic B-spline smoothing. This systematic approach ensures practicality and efficiency for material cart operations.
