REINFORCEGEN: Hybrid Skill Policies with Automated Data Generation and Reinforcement Learning
Long-horizon manipulation has been a long-standing challenge in the robotics community. We propose ReinforceGen, a system that combines task decomposition, data generation, imitation learning, and motion planning to form an initial solution, and improves each component through reinforcement-learning-based fine-tuning. ReinforceGen first segments the task into multiple localized skills, which are connected through motion planning. The skills and motion planning targets are trained with imitation learning on a dataset generated from 10 human demonstrations, and then fine-tuned through online adaptation and reinforcement learning. When benchmarked on the Robosuite dataset, ReinforceGen reaches 80% success rate on all tasks with visuomotor controls in the highest reset range setting. Additional ablation studies show that our fine-tuning approaches contributes to an 89% average performance increase. More results and videos available in https://reinforcegen.github.io/.

Case Study: The Impact of Real-time Replanning
Real-time replanning based on updated observations significantly reduces pose target prediction error and improves subsequent skill success rates, especially in tasks like Nut Assembly. This mechanism contributes to a 50% relative improvement in overall success rate for HSP.
When comparing HSP and HSP-Replan from our quantitative results, replanning alone increases the overall success rate of HSP from 44.68% to 66.88%, demonstrating its critical role in robust long-horizon manipulation.

Your AI Implementation Roadmap
A typical phased approach to integrating advanced AI robotics into your operations, leveraging ReinforceGen's principles.
Phase: Discovery & Data Acquisition
Identify key long-horizon manipulation tasks within your operations. Collect a small set of human demonstrations (e.g., 10-20) for initial policy bootstrapping, defining task stages and reference objects.
Phase: Automated Data Generation & Initial Training
Leverage ReinforceGen's object-centric data generation to expand the initial human demonstrations into a large, diverse synthetic dataset (thousands of examples). Train initial hybrid imitation learning agents (pose predictors, motion planners, skill policies, termination predictors).
Phase: Online Adaptation & Reinforcement Learning Fine-tuning
Implement online fine-tuning for all policy components using reinforcement learning. This phase focuses on real-time replanning, residual RL for skill policies, and causal inference for termination conditions to improve robustness and success beyond initial demonstrations.
Phase: Deployment & Continuous Improvement
Deploy the fine-tuned hybrid skill policies in your target environment. Monitor performance, collect additional online interaction data, and continuously iterate on RL fine-tuning or consider end-to-end distillation for specialized applications.
