DemoStart: Demonstration-led auto-curriculum applied to sim-to-real with multi-fingered robots
シミュレーションでの少数の実演と疎な報酬のみから、3本指ロボットハンドの複雑なマニピュレーション行動を自動カリキュラム強化学習で獲得し、ゼロショットで実機に転移させる手法を提案した。

We present DemoStart, a novel auto-curriculum reinforcement learning method capable of learning complex manipulation behaviors on an arm equipped with a three-fingered robotic hand, from only a sparse reward and a handful of demonstrations in simulation. Learning from simulation drastically reduces the development cycle of behavior generation, and domain randomization techniques are leveraged to achieve successful zero-shot sim-to-real transfer. Transferred policies are learned directly from raw pixels from multiple cameras and robot proprioception. Our approach outperforms policies learned from demonstrations on the real robot and requires 100 times fewer demonstrations, collected in simulation.
