ROBOPARA: Dual-Arm Robot Planning with Parallel Allocation and Recomposition Across Tasks
This paper introduces RoboPARA, an LLM-driven framework designed for dual-arm robot task planning that optimizes parallelism and efficiency. It leverages a two-stage process: Dependency Graph-based Planning Candidates Generation and Graph Re-Traversal-based Dual-Arm Parallel Planning. RoboPARA achieves significant reductions in execution time (30-50%) and higher success rates (34%) compared to existing methods, particularly in complex multitasking scenarios.
Executive Impact
RoboPARA's novel approach to dual-arm task planning drastically improves operational efficiency and reliability, setting a new standard for collaborative robotics in complex, real-world environments by maximizing parallel execution and intelligent task decomposition.

Dual-Arm Execution Schedule
RoboPARA employs a novel two-stage architecture to ensure both task correctness and optimal arm utilization. The first stage builds a directed acyclic graph (DAG) of task dependencies, refined iteratively through error correction. The second stage analyzes and optimizes DAG traversal for parallel execution, resolving deadlocks and maximizing collaboration between dual arms.
Efficiency Breakthrough
30-50% Execution Time ReductionRoboPARA significantly reduces task execution time by 30-50% compared to existing methods. This is achieved by fully optimizing task parallelism and intelligent recomposition across tasks, which was previously a critical bottleneck in dual-arm robot collaboration.

RoboPARA's unique two-stage approach and novel X-DAPT dataset enable it to outperform baselines in efficiency, reliability, and parallel execution, addressing the critical gap of under-optimized dual-arm collaboration.
Real-world Application: Robotic Kitchen
Challenge: Optimizing complex food preparation tasks in a robotic kitchen requires dynamic planning, parallel execution (e.g., cutting carrots while picking plates), and robust error handling.
Solution: RoboPARA processes user instructions to generate DAGs for tasks like 'make carrot slices' and 'cream bread'. Its graph re-traversal stage identifies parallelizable actions and assigns them to arms, ensuring synchronized and decoupled operations.
Outcome: Demonstrated a 30-50% reduction in execution time for kitchen tasks on a humanoid robot, with behaviors closely aligned with human activities, showcasing efficient parallel manipulation and collaborative dual-arm execution.
This case study highlights RoboPARA's practical effectiveness in a real-world setting, demonstrating its ability to handle complex, interleaved tasks with high efficiency and reliability, just like a human chef.
