ADEPT: Accelerating Dexterity via Pre-Training and Post-Training using Reinforcement Learning
Researchers introduce ADEPT, a reinforcement learning framework that enables robots to learn complex, long-horizon tasks using visuo-tactile perception.
- Uses a pre-training and post-training RL pipeline to accelerate skill acquisition.
- Improves sim-to-real transfer for robots with high degrees of freedom.
- Utilizes raw visuo-tactile perception for long-horizon task execution.
- Reduces the computational cost of learning new behaviors from scratch.
The ADEPT framework addresses a major bottleneck in robotics: the difficulty of training high-degree-of-freedom (DoF) robots to perform complex tasks. By utilizing a large-scale reinforcement learning approach, the system can transfer skills from simulation to the real world more effectively.
The methodology involves a two-step process. First, the model undergoes pre-training on a generic object reposing task. This creates a foundational behavior prior that can then be used during post-training for specific downstream tasks.
This approach allows multi-fingered robots to master intricate movements that would be computationally expensive or impossible to learn from scratch. By leveraging raw visuo-tactile perception, the system bridges the gap between digital training environments and physical execution.
