## Abstract
Vision-Language-Action (VLA) models have become a dominant paradigm for embodied intelligence. However, most existing approaches are built on large-scale transformers, resulting in substantial inference latency and energy consumption that limit their practical deployment in low-power, real-time scenarios. SpikeVLA is proposed as a spiking VLA architecture for embodied navigation with energy-efficient inference, consisting of three key components: (i) A spiking vision encoder, Spike-V, that replaces dense continuous layers with event-driven spiking layers to reduce the energy consumption of visual representation learning. (ii) A multi-modal spiking large language model, Spike-L, that reformulates cross-modal reasoning with spiking dynamics and token-level event-driven sparsity to further lower computational cost. (iii) A spiking action policy network, Spike-A that employs Laplacian-kernel population coding with a multi-layer fully connected SNN, and decodes spiking activities into stable and robust continuous control with energy-efficient inference under low-power constraints. Experiments on navigation and robotic control tasks show that SpikeVLA significantly reduces energy consumption and computational cost while maintaining competitive performance, highlighting its potential for low-power, real-time embodied intelligence.

## Methodology

### Three-Component Architecture

#### 1. Spike-V: Spiking Vision Encoder
- Replaces dense continuous layers with event-driven spiking layers
- Reduces energy consumption of visual representation learning
- Processes visual input through spiking neural network layers

#### 2. Spike-L: Multi-Modal Spiking LLM
- Reformulates cross-modal reasoning with spiking dynamics
- Uses token-level event-driven sparsity
- Lower computational cost through sparse activation

#### 3. Spike-A: Spiking Action Policy Network
- Employs Laplacian-kernel population coding
- Multi-layer fully connected SNN
- Decodes spiking activities into continuous control signals
- Energy-efficient inference under low-power constraints

### Key Technical Innovations
- **Event-driven sparsity**: Only active neurons consume energy
- **Laplacian population coding**: Efficient encoding of continuous action spaces
- **Full SNN pipeline**: End-to-end spiking architecture from perception to action
- **Token-level sparsity in LLM**: Dramatically reduces computation in language component

### Experimental Setup
- Navigation tasks and robotic control benchmarks
- Comparison with dense transformer-based VLA baselines
- Energy consumption measurement
- Performance-accuracy trade-off analysis

## Key Findings

1. **Significant energy reduction**: SpikeVLA substantially reduces energy consumption compared to dense transformer VLAs
2. **Competitive performance**: Maintains comparable task performance despite energy efficiency
3. **End-to-end spiking**: Demonstrates feasibility of full SNN pipeline for complex embodied AI
4. **Population coding for actions**: Laplacian-kernel approach effectively bridges spiking representations and continuous control
5. **Scalability**: Architecture scales to real-world navigation and robotic control tasks

## Implications

### For Embodied AI
- Opens path to deployment on edge devices with power constraints
- Demonstrates VLA paradigm can be implemented with spiking computation
- Enables real-time robotic control with energy-limited hardware

### For Spiking Neural Networks
- First full VLA implementation using SNNs across all components
- Validates spiking LLM concept for multimodal reasoning
- Shows population coding as viable action decoding mechanism

### For Neuromorphic Hardware
- Direct mapping to neuromorphic chips (Loihi, TrueNorth, etc.)
- Event-driven computation aligns with hardware design principles
- Enables deployment of sophisticated AI on brain-inspired hardware

## Critical Analysis

### Strengths
- ICML 2026 acceptance indicates strong peer review
- Full end-to-end spiking pipeline (not hybrid)
- Practical application domain (embodied navigation/robotics)
- Clear energy-performance trade-off analysis

### Limitations
- May lag behind largest dense VLA models in absolute performance
- Training SNNs still challenging (surrogate gradients etc.)
- Limited to navigation/control domains tested
- Latency characteristics of spiking inference not fully characterized
