Introduction
|
Robotino can now comprehend basic human speech commands. This feature is integrated in the v2.4 OS for both 1GB and 4GB CF cards. The setup is preconfigured for a Logitech ClearChat PC Wireless Stereo Headset. Read below how to modify the setup to fit your audio device. |

When the Logitech ClearChat headset is plugged into Robotino's USB port, the udev rule "/etc/udev/rules.d/99-robotinosr.rules" matches
SUBSYSTEMS=="usb", KERNEL=="hiddev[0-9]*", SYSFS{idVendor}=="046d", SYSFS{idProduct}=="0a12", RUN+="/usr/local/OpenRobotinoAPI/1/daemons/srd.sh start", SYMLINK+="headset"
udev runs "/usr/local/OpenRobotinoAPI/1/daemons/srd.sh start"
Copy "/etc/udev/rules.d/99-robotinosr.rules" to "/etc/udev/rules.d/99-myheadset.rules" and modify the new rule to fit your hardware. How to do this can be read here.
"/usr/local/OpenRobotinoAPI/1/daemons/srd.sh" uses the "/usr/local/OpenRobotinoAPI/1/daemons/configure_alsa.sh" to write a valid alsa configuration to "/root/.asoundrc". The audo interface from which card and device number are taken is given in "/etc/robotino/sr/devicename". Modify this file to match the output from "aplay -l".
Test the setup by running "/usr/local/OpenRobotinoAPI/1/daemons/configure_alsa.sh" and see if "/root/.asoundrc" is reasonable. Then run "/usr/local/OpenRobotinoAPI/1/daemons/srd.sh start". If this works test your udev rule by detaching and reattaching your USB audio device and see if srd comes up.
