How it works

Three steps from unbox to your first behavior.

1 step one

Assemble & connect

Simple assembly. Connect the battery and you're ready to go.

unbox · clip · power on
2 step two

Program with blocks

Use SentryNode Pilot to build movement, sensor logic, and autonomous behavior.

Go deeper with code

Switch to firmware and extend the platform for custom projects and research. 

void loop() {
  if (line) turn(40);
  else     fwd(70);
}

SentryNode AI Platform

Add AI to robots without
losing control.

SentryNode AI is a robotics integration workspace for teams that want to use large language models safely in robot systems. It connects to your existing ROS2 stack, keeps deterministic control where it belongs, and gives you a structured place to test, validate, and improve AI-assisted robot behavior.

LLM integration without a rewrite

Add an AI layer next to your existing stack. Your drivers, controllers, safety logic, and ROS2 nodes stay in charge of the robot.

Test AI behavior before hardware

Compare prompts, models, tool calls, and task logic in simulation or controlled test runs before they reach a real robot.

Validate every test run

Record what the AI saw, decided, and commanded. Review failures before they become field problems.

SentryNode AI does not replace your robot control stack. LLMs handle high-level reasoning and flexible task logic while deterministic software remains responsible for motion, safety, and low-level control.

Why SentryNode

Built on three principles.

Everything we make, from a beginner ESP32 kit to SentryNode AI, follows the same product logic: modular systems, fast iteration, and a clear path from learning to real robot deployment.

01

Modular

Hardware and software that compose cleanly. Sensors snap on. Libraries slot in. Your own code extends the platform without fighting it. We don't build walled gardens.

Extend it in any direction from day one.

02

Rapid prototyping

The gap between idea and moving robot should be minutes, not weeks. We obsess over setup time, documentation, and first-run experience so you can spend your time on the problem that actually interests you.

From unboxing to driving in minutes.

03

Embodied AI

AI that only chats is not enough. We build for robots that sense, move, and act. SentryNode AI is our next step toward making physical AI practical for small teams, educators, and robotics companies.

A clear path from your first robot to physical AI.

Get started

Pick your entry point.

Whether you want to build your first robot or explore safe AI workflows for ROS2-based systems, there's a starting point for you.
