🚀 Advanced Double Q-Learning for Smarter Autonomous Ground Robots 🤖 

🌍 Autonomous navigation is rapidly transforming industries, from logistics to defense. But when it comes to complex and asymmetrically distributed terrains, traditional path planning and obstacle avoidance technologies fall short. So, how do we make ground robots more intelligent and adaptive in such unpredictable environments?

The answer lies in an advanced double Q-learning algorithm enhanced with self-supervised prediction and curiosity-driven exploration 🚀.

🔑 Why Path Planning Matters

Efficient path planning is the backbone of safe and autonomous navigation. A ground robot must not only find the shortest route but also adapt to obstacles in real-time. In challenging landscapes, existing optimization techniques often struggle with slow convergence and limited adaptability.

💡 The Proposed Solution: Advanced Double Q-Learning

This algorithm brings several innovative improvements to overcome the shortcomings of traditional methods:

1. ⚖️ Reduced Overestimation & Bootstrapping

   • By modifying the target Q-value calculation and optimizing network structures, the algorithm achieves greater accuracy and stability.

2. 📊 Priority Experience Replay

   • Not all experiences are equal. Data in the experience pool is prioritized, meaning more valuable samples are revisited more often.

   • Even under-trained experiences can be effectively reused, boosting learning efficiency.

3. 🤯 Curiosity-Driven Exploration

   • A curiosity network is added to encourage robots to explore.

   • Each state receives an intrinsic reward, motivating the robot to try diverse actions instead of repeating the same paths.

   • This enhances the robot’s ability to independently select optimal routes.

📈 Performance Results

In tests against leading optimization algorithms, the proposed double Q-learning method delivered remarkable improvements in complex environments:

• 🐦 Sparrow Search Algorithm (SSA) → 18.07% improvement

• 🪲 Dung Beetle Optimization Algorithm (DBOA) → 7.91% improvement

• 🐝 Particle Swarm Optimization (PSO) → 5.56% improvement

These results demonstrate superior convergence speed, stronger adaptability, and robust performance in environments where traditional algorithms often fail.

🚀 Future of Autonomous Ground Robots

With this approach, unmanned ground robots can:
✅ Explore unknown terrains with greater confidence
✅ Choose the shortest and safest path autonomously
✅ Adapt to highly dynamic, real-world environments

This advancement bridges the gap between robotic intelligence and real-world deployment, making next-generation robots smarter, safer, and more reliable than ever before.
