This study investigates the use of adapters in reinforcement learning for robotic skill generalization across multiple robots and tasks. We propose an alternative approach where a disembodied (virtual) hand manipulator learns a task (i.e., an abstract skill) and then transfers it to various robots with different kinematic constraints without retraining the entire model (i.e., the concrete, physical implementation of the skill). Example results in simulation & real (click).


Overview Video


Generalization Across Robots

We present generalizing a learned skill i.e., opening a drawer or a cupboard, to different robotic platforms, including HSR, AliengoZ1, and A2Single.

Generalization Across Tasks

We present generalizing a learned skill to different tasks, such as from drawer opening to door opening and chair pushing.

Real Experiments

In the real experiments, we perform the drawer opening task and chair pushing task with a real HSR robot.

The below video shows the chair pushing task.
