Efficient robotic planning achieved through smaller AI models and real-time adaptation.
DaDu-E introduces a robust closed-loop planning framework that enables robots to perform complex tasks using smaller LLMs. It achieves this by combining encapsulated skill instructions, visual feedback, and memory augmentation, reducing computational costs while maintaining high performance.

🤖 Original Problem:
Existing robotic systems using LLMs as planners are computationally expensive and prone to errors due to open-loop systems. They rely on large models deployed on cloud servers, making real-time operation challenging.
-----
🔧 Solution in this Paper:
→ DaDu-E implements a lightweight LLM with three key components: encapsulated robot skill instructions, robust feedback system, and memory augmentation.
→ The system restricts operational scope and uses a lean instruction set with just three core skills: navigate, grasp, and place.
→ A dual-memory system combines short-term object tracking with long-term semantic mapping.
→ Visual feedback enables dynamic replanning, allowing the robot to adapt to environmental changes in real-time.
-----
💡 Key Insights:
→ Limiting robot scope and instruction sets can significantly reduce computational complexity
→ Closed-loop control with visual feedback improves task success rates
→ Memory augmentation reduces latency in repetitive tasks
→ Local server deployment is possible with optimized architecture
-----
📊 Results:
→ Achieves comparable success rates to larger models while reducing computational requirements by 6.6x
→ Operates effectively on local servers instead of cloud infrastructure
→ Average prompt length reduced to 543 tokens
