Core Viewpoint - The article discusses the post-training strategies of Vision-Language-Action (VLA) models from the perspective of human motor skill learning, emphasizing the need for robots to undergo a post-training phase to adapt to specific tasks and environments, similar to how humans learn skills through practice and experience [4][5][9]. Summary by Sections 1. Introduction to VLA Models - VLA models integrate visual perception, language understanding, and action generation, enabling robots to interact with their environment effectively. However, their out-of-the-box performance is often insufficient for complex real-world applications, necessitating a post-training phase to refine their capabilities [8][9]. 2. Post-Training Strategies - The article categorizes VLA model post-training strategies into three dimensions: environment perception, embodiment (body awareness), and task understanding. This classification mirrors the key components of human motor learning, facilitating targeted improvements in specific model capabilities [10][12]. 3. Environmental Perception Enhancement - Strategies include enhancing the model's ability to perceive and adapt to various operational environments, utilizing cues from the surroundings to inform actions, and optimizing visual encoding for task-specific scenarios [12][13]. 4. Body Awareness and Control - The post-training strategies focus on developing internal models that predict body state changes, improving the model's ability to control robotic movements through feedback mechanisms inspired by human motor control [14]. 5. Task Understanding and Planning - The article highlights the importance of breaking down complex tasks into manageable steps, akin to human learning processes, to enhance the model's understanding of task objectives and improve operational planning [14]. 6. Multi-Component Integration - Effective skill acquisition in humans involves synchronizing multiple learning components. Similarly, VLA models benefit from integrating various strategies to optimize performance across different dimensions [14]. 7. Challenges and Future Trends - Despite advancements, challenges remain in enabling robots to learn and adapt like humans. Key areas for future research include improving kinematic models, optimizing action output structures, and enhancing human-robot interaction through expert knowledge integration [16][17][18]. 8. Continuous Learning and Generalization - The need for continuous learning capabilities is emphasized, as current VLA models often struggle with retaining previously learned skills.
