A brain-inspired, tri-level hierarchical architecture, NeuroVLA addresses the sensorimotor paradox in embodied intelligence. Traditional Vision-Language-Action (VLA) models suffer from high latency and "temporal blindness," hindering fluid, fast robotic control. NeuroVLA decouples high-level cognition from low-level motor control, enabling rapid, precise, and safe robotic responses for researchers and engineers developing advanced embodied AI systems.

How It Works

NeuroVLA employs a bio-inspired, tri-level hierarchy: Cortical (semantic planning), Cerebellar (adaptive prediction/timing), and Spinal (Spiking Neural Network for asynchronous actuation). The SNN-based spinal module exploits temporal sparsity, minimizing end-to-end latency and enabling efficient, hardware-localized learning for real-time reflexive behaviors, mimicking biological motor systems.

Quick Start & Requirements

• Prerequisites: Linux (Ubuntu 20.04/22.04 recommended), Python 3.10+, NVIDIA GPU with CUDA.
• Installation: Conda environment setup, PyTorch (with CUDA), pip install -r requirements.txt, pip install flash-attn --no-build-isolation.
• Usage: Training (scripts/run_libero_train.sh), Evaluation (client/server: examples/LIBERO/run_server.sh, examples/LIBERO/eval_libero.sh).
• Resources: Docs and quick-start guides are within the AlphaBrain ecosystem (alphabraingroup.github.io/AlphaBrain, docs/quickstart/neurovla.md).

Highlighted Details

• Over 75% reduction in kinematic jerk for fluid motion.
• < 20 ms latency for collision-triggered survival reflexes.
• Emergent temporal and spatial sparsity in the neuromorphic spinal layer.
• LIBERO benchmark: PLIF SNN head achieved 95% success on long-horizon tasks.
• Biologically-plausible e-prop learning matches BPTT performance at matched budget.

Licensing & Compatibility

Licensed under GNU Affero General Public License v3.0 (AGPL-3.0). This strong copyleft license requires that any derivative works or services offered over a network using the software must also be made available under the AGPL-3.0. This poses significant restrictions for integration into proprietary, closed-source commercial products.

Limitations & Caveats

Currently "Under Review" for Nature, indicating a research artifact status. The AGPL-3.0 license is a major consideration for commercial adoption. Setup requires careful environment management and specific hardware (NVIDIA GPU with CUDA).
