Bringing Robotics AI to Embedded Platforms: Dataset Recording, VLA Fine‑Tuning, and On‑Device Optimizations

Recent advancements in Large Language Models have facilitated the evolution from text-only reasoning to multimodal systems, integrating visual perception and, more recently, generating robotic actions in Vision–Language–Action (VLA) models. Deploying these models on embedded robotic platforms presents challenges due to constraints in compute power, memory, and real-time control requirements. Asynchronous inference is proposed as a solution, allowing for smoother and continuous motion by separating generation from execution, provided that inference latency remains shorter than action execution duration. This transition from model compression to a systems engineering problem requires architectural decomposition, latency-aware scheduling, and hardware-aligned execution to effectively translate multimodal foundation models into practical systems. NXP's guide offers hands-on practices for recording reliable robotic datasets, fine-tuning VLA policies, and optimizing real-time performance on platforms like the NXP i.MX95, which integrates multiple CPUs, a GPU, and an NPU to support efficient edge inference with multi-camera capabilities. The guide emphasizes the importance of high-quality data, diverse datasets, and the use of a gripper-mounted camera to improve task success rates. It also outlines the decomposition of VLA models into logical stages for optimized deployment and highlights the role of asynchronous inference in enhancing control frequency and recovery behavior.
