Kovan is another offering from Sutajio Ko-Usagi, the Open Source hardware company led by Andrew 'bunnie' Huang. Kovan is a smart robotics controller targeted at applications that require fully autonomous operation and high levels of integration. Kovan integrates onto a single PCB all the features you need to build a self-guided robot:
The native development environment for Kovan is based upon OpenEmbedded, the same system used by the Beaglebone. Sutajio Ko-Usagi's PCBA-only version of Kovan comes with C and Python support out of the box, so you can get started right away with development -- no need to set up cross-compilers. For more information on the software environment, please visit Kosagi's site.
The package offered in limited quantities at Adafruit for $249 is the Kovan main board and power supply for development use, configured as a battery emulator, intended for intermediate and advanced developers who can roll their own battery and casing solution.
This board is the heart of the 501©(3) non-profit KISS Institute for Practical Robotics' next-generation controller, valued at $400. KIPR's solution will come with a case, integrated battery, LCD, speaker, and an enhanced development environment suitable for entry level hobbyists and students; it will be available for purchase in January at the Botball store.
