This is a fork of the dbw_mkz_ros package that is used for connecting to and configuring the Dataspeed Drive-by-Wire Kit for Lincoln MKZ / Ford Fusion vehicles. It may also work for other vehicles compatible with the Dataspeed Drive-by-Wire Kit, though this is not guaranteed. This fork has been modified to allow for building a Docker image that can serve as a CAN driver for the CARMA Platform.
Assuming the CARMA Platform is installed at ~/carma_ws/src,
cd ~/carma_ws/src
git clone https://github.com/VT-ASIM-LAB/dataspeed_can_driver.git
cd dataspeed_can_driver/docker
sudo ./build-image.sh -d
After the Docker image is successfully built, connect the Drive-by-Wire Kit USB cable to your device and run lsusb in the terminal to determine which bus and device number it has been assigned to. Assuming here that it is Device 007 on Bus 001, add the following lines to the appropriate docker-compose.yml file in the carma-config directory, and make sure that the current user (and not root) is the owner of /dev/bus/usb/001/007.

Finally, add the following lines to the drivers.launch file in the same directory as docker-compose.yml.
