VLA Model-Expert Collaboration for Bi-directional Manipulation Learning

Understand

The emergence of vision-language-action (VLA) models has given rise to foundation models for robot manipulation.

• Although these models have achieved significant improvements, their generalization in multi-task manipulation remains limited.
• This study proposes a VLA model-expert collaboration framework that leverages a limited number of expert actions to enhance VLA model performance.
• This approach reduces expert workload relative to manual operation while simultaneously improving the reliability and generalization of VLA models.
