🤖 Robotics Communications: The Digital Nervous System

Modern robotics requires a multi-layered communication strategy. This documentation covers the protocols used to bridge high-level N100 computer-vision logic with low-level ESP32 and Pico motor control.

The Mission: To create a robust, noise-resistant network that allows modular "nodes" like robot arms and eyes to function as a single unit.

Experimental Implementation

The Experimental Lab is where theory meets hardware. Each stage of the nervous system is validated through isolated test environments to ensure stability before full system integration.

Hardware & Software Strategy: All experiments utilize the ESP32-S3 (N16P8) and follow a modular validation process—starting with simple GPIO "heartbeats" and scaling to multi-node differential signaling.

Full System Diagrams: Detailed schematics showing the interplay between the N100 orchestration layer and MCU endpoints.
Stage-Based Validation: Step-by-step firmware deployments focusing on specific protocol reliability (UART, I2C, CAN).
Silicon Life Tests: Proving fundamental hardware execution before introducing bus noise or peripherals.

Hardware Ecosystem

N100 Desktop: Orchestrates high-level AI and sends hex-commands via UART.
ESP32-S3/C3: Handles Bluetooth commands and bridges Vision/BT data.
Arduino Nano/Pico: Specialized nodes for CAN Bus endpoints in limbs and sensors.
Signal Integrity: Utilization of level-shifting (3.3V to 5V) and differential signaling (CAN) for stability.
