Build on a common core.
SLEIPNIR is a family of stackable modules for vehicle control, onboard computing and power. Start with the flight controller; the wider library is in development.
MODULAR ELECTRONICS FOR ROBOTICS
Build the mission. We’ll help with the electronics.
Stackable hardware for autonomous vehicles. Board-specific AI assistance to help your team connect, configure and debug it.

HERMOD Coming soon
Meet Hermod.
Your AI’s hardware guide.
Connect your AI assistant to Aesir’s board knowledge, so it can help your team wire, debug and write firmware. Aesir doesn’t see your code or prompts. Your AI sends separate board-documentation requests.
Wire it. Measure it. Code it.
01 / THE PLATFORM
Your next vehicle shouldn’t
start from zero.
Robotics teams spend too much time connecting the basics. Aesir brings the electronics and the knowledge to use them into one platform.
Get the board context.
Hermod gives your AI assistant Aesir’s board documentation, pinouts and firmware context, matched to your hardware revision. Aesir doesn’t see your code or AI prompts.
Focus on your application.
Use a reusable electronics foundation while your team develops the vehicle, sensors, software and mission-specific behaviour around it.
ONE MODULAR APPROACH
Aerial/Surface/Subsea
Developed through subsea robotics.
Designed for reuse across vehicle types.
02 / START WITH THE HARDWARE

An optional add-on for additional onboard inference capacity.
03 / MEET HERMOD Coming soon
Your AI.
Our board knowledge.
Get help with the work between writing code and getting hardware to respond.
Hermod connects your existing AI assistant to Aesir’s board documentation. It helps your team wire, measure and write firmware against the right hardware context.
Your code and prompts stay with you and your AI.“Where do my thrusters connect?”
Identify the connector and signal pins, check the grounding, and see the power constraints before you wire.
Simulated session. Board answers shown are real output from Hermod.
Read the example
An engineer asks how to connect eight thruster speed controllers. Hermod supplies connector J2’s pinout, flags that it provides signals rather than motor power, and gives the agent relevant firmware settings.
HERMOD / PRIVACY
Aesir doesn’t see
your code or prompts.
Your AI asks Hermod for board knowledge. Your source code and AI conversations stay with you and your chosen AI provider.

Illustrative flow. Blurred content represents your private session; the request and answer are separate documentation exchanges.
Your chosen AI provider’s data policies still apply.
How does it connect to my AI assistant?
Hermod connects through MCP, a protocol that lets compatible AI assistants use external tools and information. Pilot access is coming soon. Register your interest; setup instructions and compatibility guidance will be shared when pilots open.
Your assistant can then ask Hermod for Aesir board information while you work in your existing conversation.
Can Aesir see my code or prompts?
No. Aesir does not see your source code, AI prompts or conversation history. Those stay with you and your chosen AI provider.
Your assistant sends Hermod separate board-documentation requests, such as “Which pins are on J4?” Hermod returns the relevant pinouts, specifications and firmware guidance.
Your AI provider’s own data handling settings and policies still apply.
What does “bring-up” mean?
Getting a board connected, configured and working for the first time: checking wiring and power, confirming that peripherals respond, and preparing the firmware. Your engineers carry out and validate the physical work.
04 / WHY AESIR
Built by people who build
autonomous systems.
Our work spans board design, vehicle integration, and guidance, navigation and control. The SLEIPNIR architecture has already been tested on a subsea robotic vehicle.
FROM VEHICLE DEVELOPMENT
TO A REUSABLE PLATFORM
TO A REUSABLE PLATFORM
We started with the electronics work that robotics teams repeat. Our first commercial product is the SLEIPNIR Flight Controller. The next step is a wider module library, supported by tools that make its integration easier.
