A connected computer for rapid robot development

The next industrial revolution is happening right now. New connected devices and robotics are redefining the way work is done. Big business has already realized that the way of the automation and high-tech robot-based manufacturing is the way of the future. Now the same trend is transforming the consumer and services markets. There is no better time to be a robotics engineer and maker - the world needs your bold ideas. You only need tools to make them happen.

What is Husarion CORE2?

Husarion CORE2 is a computer designed for fast prototyping of robotic projects. It interfaces directly with motors, servos, encoders, sensors, so without additional shields you can easily build large variety of robotic of mechatronic projects.

It is available in two configurations:

CORE2 - a low-power, cloud connected real-time computer with Wi-Fi
CORE2-ROS - an ROS powered, cloud connected computer with Wi-Fi combining real-time capabilities and high computing power. Ideal for autonomous robots.

What is Husarion platform?

It’s not only about hardware. Wouldn’t it be great if robotics was as simple as coding a website? Web developers enjoy proven, ready-to-use tools, frameworks, hosting platforms, tutorials, and examples. If only you, the robotics developers, could enjoy the same advantages. It would remove unnecessary work from your shoulders and let you focus on what really matters - the idea, the problem your device will solve and how it will do it.

develop online or offline with Husarion CORE2
develop online or offline with Husarion CORE2

That’s the goal that we’ve set for ourselves creating the Husarion platform. We provide you with embedded hardware, preconfigured software, and easy online management. You can start building your first prototypes with LEGOs and iterate them with subsequent 3D-printed or laser-cut versions of mechanics without having to develop hardware and software from scratch. From the very beginning of your project up to mass manufacturing and deployment, you can use the same Husarion solutions every step of the way.

Building advanced robots should be as easy as creating websites. This is the challenge we took on.

Who is Husarion platform for?

Our tools are meant to accompany your robotics project throughout development - from humble beginnings in your garage to fully-fledged development facility and mass manufacturing. It doesn’t matter if you are:

…the Husarion platform will jump-start your robotic project.

Intrigued? Let’s take a look at hardware details that makes it all work.

Hardware Specifications

CORE2 contains popular interfaces for robotic projects, so you can build different robots easily without dozens of shields. Built-in DC motor ports allows you to directly connect up to four motors and process signals from their quadrature encoders in hardware - you don’t waste a CPU processing cycles, because a dedicated timer, one for each encoder, cares to not miss any single “tick”. Powerful libraries for CORE2 use all peripherals and CPU power in efficient way, thanks to a real-time operating system, DMA channels, interrupts - but everything is hidden behind an easy to use API. Interfaces for six servos and an on-board DC/DC converter allows you to select a voltage level for each servo. Lots of GPIOs, communication interfaces, ADC channels, and interrupt pins allow you to connect literally any sensor you can find, especially since CORE2 works with Arduino libraries, as you will see later.

What can I create with Husarion CORE2?

Whether your next robotic idea is a tiny rover that penetrates tunnels, a surveillance drone, or a room-sized 3D printer, the CORE2 can serve as the brains behind it.

CORE2 will accelerate building a large variety of robots in all sorts of appliances. Need further inspirations? How about:

And we’re sure that you’re already imagining even cooler use cases!

What software is used with CORE2?

Open source, real-time framework

A set of libraries for robots has been in development at Husarion for four years now. They are written to save computing power of CPU and perform low-level real-time functions of robot efficiently. These libraries, named “hFramework”, are based on a real time operating system (RTOS) and use DMA channels and interrupts internally to handle communication interfaces. Need a new PID regulator for your motor working on a separate task in real time? It’s only a few lines of code. We believe in the power of hFramework and we’ve made it open-source: hFramework on GitHub

Powered by ROS

ROS is a great set of tools for building autonomous robots. It’s becoming a standard for new robotic designs. CORE2-ROS controller integrates a dedicated Linux image with ready-to-use ROS packets and libraries that will help you to benefit from the synergy of low-level, real-time tasks realized by CORE2 and high-level tasks realized in a single board computer. Along with CORE-ROS, we’ve prepared a set of tutorials to help you get started with ROS and CORE2. Currently covered topics include:

  1. ROS introduction
  2. creating nodes
  3. simple kinematics for mobile robot
  4. visual object recognition
  5. running ROS on multiple machines
  6. SLAM navigation

All topics can be covered using ROSbot - autonomous robot mobile platform with CORE2-ROS.

There is no easier way to start building your own ROS powered robots!

Arduino compatible

CORE2 works with Arduino libraries! There are Arduino libs for literally any sensor available on the market. You can find them easily on the web and use them directly with CORE2 controller, without having to modify them to work. The Arduino compatibility layer uses the hFramework API, so CORE2 peripherals are used in a very efficient way.

What is the use of Husarion cloud?

It’s a command center for all your Husarion powered robots. With our Cloud you can:

Create the WebUI - a dedicated user interface to allow controlling your robot in real time and streaming the video - thanks to HTML5, CSS and built-in WebRTC support.

Share your robot with different access rights and generate a link to your robot anybody can open.

Develop robot firmware and program robots through a web interface.

Feel safe thanks to a full SSL connection between CORE2 and cloud. Access your robots from a 3rd party apps with a cloud API.

What does the software development process for my robots looks like?

Husarion provides both a cloud-based WebIDE and an offline SDK.

  6. 2x left & 2x right DC motors with quadrature encoder
  7. CORE2-ROS (with ASUS Tinker Board inside)

Our ROS tutorial is based on this platform. This is the easiest way to start building your own autonomous mobile robots. Mechanics are assembled and ready to use.

Do you have any external modules for CORE2?

We have prepared some add-ons for CORE2/CORE2-ROS:

CORE2brick - connects CORE2 or CORE2-ROS with LEGO® Mindstorms.

CORE2 + CORE2brick is a perfect match for all robotics beginners starting with Mindstorms as well as academics, to a provide closer-to-business platform for educating students. The central component is the shield that provides full compatibility with LEGO® Mindstorms sensors and motors, including current sources and UART or I2C interfaces. The kit also contains cables, battery pack and all mechanical elements needed to connect CORE2 with bricks. CORE2-ROS shown under CORE2brick shield is not included in this add-on.

  1. a battery pack for 3x 18650 Li-Ion
  2. 4x LEGO® motor
  3. 6x LEGO® sensor
  4. acrylic adapters
  5. cables to connect LEGO® motors and sensors with LEGO® Connector

CORE2block - connects CORE2 or CORE2-ROS with Makeblock system. The metal, screwed mechanicals of Makeblock gives you more robust mechanics than LEGO® bricks.

The main components are adapters for sensors and motors. The electrical interface of Makeblock sensors is similar to CORE2 hSensor, but some pin-swapping is needed, so these adapters do that job.

  1. to CORE2 sensor ports
  2. to Makeblock motors
  3. to CORE2 motor outputs
  4. to Makeblock sensors

Servo controller - allows to connect 12 additional servos to CORE2.

Communicates with CORE2 via hSensor interface. Up to four servo controllers can work on one hSensor port thanks to 2-bit addressing. The step down DC/DC converter with software-controlled output voltage is available on board to simplify power connections - you can supply the servo controller and CORE2 from the same power source.

Servo controller for CORE2
  1. outputs for 12 servos, with selectable output voltage (5V/6 V/7.4 V/8.6 V), 4 A max. output current and with OC and UV protection
  2. status LEDs
  3. jumper for address selection
  4. UART interface
  5. power supply input

Manufacturing Plan

The CORE2 is not our first robotic controller. We’ve been making them for over four years now, and we shipped the crowdfunded RoboCORE as our first product. The CORE2 is a result of our continued iteration and experience, and incorporates a lot of know-how we’ve acquired throughout our journey.

Now we have a final design ready, with complete BOMs fully specified. We’ve negotiated with vendors and distributors and currently all parts are available with a maximum one month lead time. Depending on pre-ordered volumes during the Crowd Supply campaign, we will choose a right contract manufacturer. They can organize all production and start immediately after the supply chain process finishes.

Our priority will be to minimize the time to ship orders to you. We set the shipping dates with safe margins. Having worked with multiple fulfillment centers in the past, we will pick the best, proven ones that will ensure a smooth ordering experience for you.

Risks & Challenges

There is always some risk related to producing hardware in volume, like natural disasters, supply chains problems, and quality assurance. But we’ve done everything possible to reduce risk to a minimum before launching our Crowd Supply campaign. CORE2 is the second generation of our computer for robots that we will send to clients, so we have a lot of experience that helps us to avoid potential problems. CORE2 hardware is tested by our team and beta-testers, and is ready for a mass production. We prepared the Automatic Test Equipment (ATE), that allows us to test and program initial firmware for CORE2 and CORE2-ROS in a short time without a risk of human error.

A development of stable software also takes a lot of time, but everything that we have prepared for CORE2 — libraries, packets, extensions, mobile apps, and cloud platform — has been tested and works stably.The software has already been used by clients around the world.

We also have experience in working with fulfillment companies that helped us before in shipping our products worldwide. Supply chains issues, quality assurance and other potential problems shouldn’t cause a major delay. Nevertheless, we will inform you about any issues, will keep you updated on the campaign, and and will be responsive to your questions. We will challenge every potential issue to bring you quality product within short time.


Q: Will it be possible to buy the additional modules after the end of the campaign?

A: Yes, all rewards prepared for this campaign will be available to buy - sooner or later after the campaign. If you need something particular or ASAP - please contact us.
