Introduction

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:

Actuator capability

Sensing capability

Connectivity

UI

Processing

Battery

The native development environment for Kovan is based upon OpenEmbedded, the same system used by the Beaglebone. 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.

A package consisting of the Kovan main board and battery emulator power supply, intended for intermediate and advanced developers who can roll their own battery and casing solution, is offered at Adafruit for $249.

This board is the heart of the 501(c)(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.

Tips & Tricks

The battery plug on kovan requires a Molex housing 0039013022 (Digikey WM1021-ND) with crimp terminals 0039000207 (Digikey WM3116CT-ND)

To use Kovan without a battery, plug a 7.5V power supply (such as Digikey 62-1169-ND) into the battery plug. Do not simultaneously plug power into the main power input, as this will cause the board to attempt to "charge" the emulating power supply.

FPGA

To reset and reprogram the fpga, do:

fpga-reset.py
cat <yourbitfile.bit> > /dev/fpga

To replace the default FPGA configuration, replace the file

/lib/firmware/kovan-lx9.bit

with your bitfile. Note that this only replaces the post-boot configuration; there is also another copy in u-boot that should also be replaced using the command

config_util --cmd=putblock --block=LX9 < <yourbitfile.bit>

Setting up wifi

Setting up wifi on a kosagi-build requires configuring network manager. Please see networkmanager kovan wifi.
