Welcome to Hedgehog!

Hedgehog is a robot controller: a device for controlling robotics components. Hedgehog is particularly suited for educational use, but great care was taken to make it flexible and usable in a wide range of use cases. Its most important features and properties are as follows:

• full control over your device

  • use all capabilities of the built-in Raspberry Pi 3
  • all open hardware and software
  • no limitations for advances users

• easy connectivity to programming devices

  • wired via Ethernet
  • wireless via WiFi
  • Web-based Hedgehog IDE or SSH

• unified command protocol

  • control your Hedgehog locally or over the network
  • protocol stack designed for reliability
  • easy to implement in many popular programming languages
  • few assumptions to allow for diverse programming interfaces

• versatile application programming interfaces (APIs)

  • visual programming via Blockly
  • textual programming mainly via Python, but node.js already supported as well
  • simple, yet not limiting

• made for tinkering and hacking

  • compatible with RC servos & DC motors, various analog and digital sensors
  • controller case can be mounted to Lego models
  • hardware blueprints (case & circuit boards) available for modification
  • microcontroller toolchain, git, … pre-installed on the controller

• classroom ready

  • One WiFi for all controllers avoids network congestion
  • many educational use cases, appropriate for various ages
  • visual & textual programming, closed-loop control, autonomous driving, microcontroller programming, distributed systems, swarm intelligence, …
