husarion-astra

husarion-astra is a Linux snap that contains the software needed to bring Astra cameras up. It is intended for Linux users working with Astra camera hardware and a ROS-based setup. In the MirrorNest catalog, it belongs to the System Tools category because it provides camera driver and runtime configuration software rather than a general-purpose application.

The snap exposes two configurable parameter groups named driver and ros. The driver group uses astra1 as its camera name by default. Its camera-params setting uses camera parameter files from /var/snap/husarion-astra/common/camera-params-.yaml, while ffmpeg-params uses files from /var/snap/husarion-astra/common/ffmpeg-params-.yaml. Both settings default to default and can be changed to identify other parameter configurations.

The ros group controls values used by the ROS driver. ros.domain-id defaults to 0 and sets ROS_DOMAIN_ID, while ros.localhost-only defaults to 0 and sets ROS_LOCALHOST_ONLY. ros.transport defaults to udp and supports udp, shm, builtin, rmw_fastrtps_cpp, and rmw_cyclonedds_cpp, with corresponding DDS XML files available in /var/snap/husarion-depthai/common and custom FastDDS setups supported there. ros.namespace is unset by default and provides a namespace for all topics and transforms.

Parameters are changed with the snap set command, including driver.name, driver.camera-params, and driver.ffmpeg-params settings. MirrorNest links directly to the official release instead of hosting a mirrored copy. The listed license is unknown, so license information is not established by the catalog entry.
