Our Vision

Simply. Robotics.

Open Source

All components of the Hedgehog Controller are available as open source and open hardware. Check out our GitHub Organization!


Simple for beginners, powerful for pros. The controller is designed to be suitable for K-12 students as well as advanced hobbyists and even in research and industry.


We want to make Robotics accessible for everyone to promote STEM fields and research projects.

    An Idea is Born

    The vision of a low-cost educational robotics controller was born. First, Android smartphones were used as processing unit. In July 2012 the first version of the controller was presented.

    The second revision of the controller was based on a box design, with a clear distinction between low-level and high-level control. The IDE was still app-based.

    New Concept, New Outfit!

    After some changes in the controller's architecture, the former AndriX controller was renamed to Hedgehog. Not only did we have a major name and concept change, but launched a Kickstarter that unfortunately was not backed.

    Web-based IDE

    From the lessons learned, we switched to a web-based IDE including visual programming. No app is required, the IDE runs directly on the controller. This also enables real-time collaboration and version control on PC, smartphone or tablet! And it is more powerful and even smaller than ever before.

It's probably not best practice to blow one's own horn, but this team is really the most amazing team I've ever worked with. We just finished a week of ECER conference, with everyone spending 18h+ per day, working passionate and committed for the cause of educational robotics. Since this is my last day of working for PRIA, I just wanted to say thank you! Team PRIA, you're awesome, it was a pleasure for me to have you in my life as working colleagues and friends. I wish you all the best for the future and I will always keep you in my mind in my mission of protecting the environment.
– For the oceans, Reinhard.

Hedgehog was initially developed within the project SCORE! in the frame of the COIN program, an initiative by the Austrian Federal Ministry of Science, Research and Economy as well as the Austrian Federal Ministry for Transport, Innovation and Technology.

Parts of the current Hedgehog development activities are funded by the EU Horizon 2020 programme within the project ER4STEM with the project reference no. 665972.

“I like Hedgehog: Hedgehog is like the Eagle made in Austria. It gives beginners a smooth introduction to software development without spending hours on electronics and mechanics beforehand. It’s powerful, sophisticated and even looks great.”

“For me an educational robotics controller like Hedgehog combines all elements to equip young people with not only digital competencies like graphical and textual programming, but also building their first robots - both in a versatile and simple way. Hedgehog as well as the Digital Literacy Initiative of DigitalCity.Wien make no difference between young children and youths, meeting all digital educational requirements of this target group.”

“I followed the evolution of the Hedgehog controller for years, and therefore knew the potential of it already. When PRIA came up with the current version of this little fellow, I was amazed: it is small, has all the capacities I want to see in a controller and most importantly is very simple to use and reliable.”
