nanobot + reComputer RK + Local LLM

A complete guide to installing and using the USB Relay Control and Light Sensor Reader skills with Nanobot on reComputer RK (featuring the RK1826 accelerator) alongside a local LLM.

Prerequisites

Hardware Requirements

DeviceRAM
reComputer RK8GB
RK1826\
DevicePortDescription
USB Relay/dev/ttyUSB11-channel or multi-channel relay module
USB Light Sensor/dev/ttyUSB0BH1750 or similar lux sensor

System Requirements

  • OS: Linux (Ubuntu, Debian, Fedora, etc.)
  • Python: 3.10 or higher
  • Permissions: User must be in dialout group for serial port access

Note:Before getting started, please make sure you can run the Qwen model on the RK1820. Please refer to the link

Install nanobot

Step 1: Install uv

bash
# Install uv
curl -LsSf https://astral.sh/uv/install.sh | sh

Step 2: Install nanobot

bash
# Install nanobot
    uv tool install nanobot-ai

Step 3: Configure nanobot

Use command below to open nanobot config.json

bash
nano ~/.nanobot/config.json

Then change the agents and vllm config like below:

json
    "defaults": {
      "workspace": "/home/~/.nanobot/workspace",
      "model": "rkllm/Qwen3",
      "provider": "vllm",
      "maxTokens": 8192,
      "temperature": 0.1,
      "maxToolIterations": 40,
      "memoryWindow": 100,
      "reasoningEffort": null
    }
    "vllm": {
        "apiKey": "nano",
        "apiBase": "http://127.0.0.1:8080/v1",
        "extraHeaders": null
    },

Note: You can add your channel refer this link.

Use nanobot

Start nanobot

Use command below to start nanobot:

bash
nanobot gateway
nanobot agent

Install clawhub

You can use the following content in the chat box to instal clawhub:

bash
Please install clawhub use command：npm install -g clawhub

Install skill with clawhub

You can use the following content in the chat box to install skills:

bash
Please install control-usb-relay use command: npx clawhub install Control-Usb-Relay
Please install usb-light-sensor-reader use command: npx clawhub install Usb-Light-Sensor-Reader

Use Skills

Prompting AI Agents

When working with AI agents, use clear prompts that reference the skills:

Example Prompts

For Relay Control:

bash
Use the control-usb-relay skill to turn on the connected device.

For Sensor Reading:

bash
Read the current light level using the usb-light-sensor-reader skill.

For Automation:

bash
Create an automation that turns on the relay when the light sensor detects 
darkness (below 100 lux) and turns it off when it's bright (above 500 lux).

Result

You can see the process of the Qwen model running locally and the results of nanobot's execution.
