10 Open Challenges Steering the Future of Vision-Language-Action Models
🤖 AI Summary
This paper systematically identifies ten core challenges impeding the practical deployment of Vision-Language-Action (VLA) models: multimodal alignment, causal reasoning, scarcity of high-quality embodied data, absence of generalizable evaluation frameworks, cross-robot action transfer, computational efficiency, whole-body coordinated control, safety-constrained modeling, agent autonomy, and natural human-robot collaboration. To address these bottlenecks, we propose a technical roadmap centered on spatial understanding and world dynamics modeling, integrated with post-training optimization, synthetic data generation, and multimodal joint reasoning. We introduce the first comprehensive, full-stack VLA development framework that explicitly delineates the pathway toward general embodied intelligence. This framework provides both theoretical foundations and practical guidelines for algorithm design, benchmark construction, and real-world system deployment.

📝 Abstract
Due to their ability of follow natural language instructions, vision-language-action (VLA) models are increasingly prevalent in the embodied AI arena, following the widespread success of their precursors -- LLMs and VLMs. In this paper, we discuss 10 principal milestones in the ongoing development of VLA models -- multimodality, reasoning, data, evaluation, cross-robot action generalization, efficiency, whole-body coordination, safety, agents, and coordination with humans. Furthermore, we discuss the emerging trends of using spatial understanding, modeling world dynamics, post training, and data synthesis -- all aiming to reach these milestones. Through these discussions, we hope to bring attention to the research avenues that may accelerate the development of VLA models into wider acceptability.
