AU Robot Servers

Documentation of AU robot servers

AU Robot Servers is a software infrastructure that can combine a number of functional modules to a robot with functionality at higher abstraction levels.

Static Plug-ins

Static plug-ins is part of the server code, and can be loaded without any additional files, see:

>> module help

To get the available list of static plug-ins (and a short description)

The three Coordinate systems are available as static: odometry (odoPose), UTM (utmPose) and Map (mapPose)

File plug-ins

This is a list of the current available plug-ins in release 2.176:

The intension is that there should be a wiki page for each with further description.

• auavoid.so.0 - visual graph obstacle avoidance (not stable)
• auballfinder.so.0 - sample blob finder in a camera image
• aucamcog.so.0 - a sample center of gravity plug-in for part of a camera image
• aucamfocus.so.0 - a focus (contrast) calculation on a camera image.
• aucron.so.0 - a module to execute bash commands at regular intervals - e.g. to move logged images at low priority
• audrivepos.so.0 - drive control to a specific pose (uses auavoid)
• auefline.so.0 - sample line finder plugin extended to find and maintain wall lines. Is based on the libauextractfeatures library.
• augps.so.0 - a gps plugin, that maintains an UTM pose from a serial/USB GPS connection
• aulmsnear.so.0 - a small function to return the closest point in a laserscan as a <laser l0=0.0 .../> type message
• (aumission.so.0 - is now renamed to aurule Mission monitor sequencer)
• aurule.so.0 - A rule based mission sequencer - Rule based mission sequencer
• auroaddrive.so.0 - a drive controller thet follows a road edge (uses auavoid, ausmr and ulmspassable)
• auseq.so.0 - deprecated mission sequencer - use aurule.so.0.
• ausmr.so.0 - smr interface
• ausvs.so.0 - a not quite finished Videre Design stereo camera plug-in
• uexres.so.0 - sample resource share plug-in - works with uexuse
• uexuse.so.0 - sample resource share plug-in - works with uexres
• ulmspassable.so.0 - extracts road lines from a laserscan (tilted laser)
• ulmsv360.so.0 - virtual 360 deg laser scanner device. This is also available as static plug-in for the ulmsserver.
