AU Robot Servers

Versions

The released versions are here: http://server.elektro.dtu.dk/ftp/jca/mobotware/

and a few comments for the releases in Release notes

Latest version:

On Jensen: (in /usr/local/smr/bin) is 2.870 (from 20 April 2010).

The Jensen version is kept at this version until course 31388 finishes (until ~ 1 june 2010)

On SVN: is version 2.920.

NB! the svn version can not directly load plugins compiled against version 2.870 (or earlier).

In version 2.920 the server core is updated to make the minimum plug-in design (one cpp file) and still use all server resources (global variables, call to other plugins etc).

NEW! BUG reporting page here: Change requests (if you do not have write access, then send me a mail mailto:jca@elektro.dtu.dk)

Installation notes=

Installation without FIREWIRE

If you do hat have (and should not use) firewire, then the AURS can be compiled by changing two of the Makefiles:

library ucam4 (in subdirectory ucam4):

In the Makefile change the DEFINES line from

DEFINES = -D USE_IEEE1394

to

DEFINES = -D USE_NO_IEEE1394

And the cameraserver (in directory ucamserver)

In the Makefile change the DEFINE line from

DEFINES = -D USE_IEEE1394

to

DEFINES = -D USE_NO_IEEE1394

and the LDDFLAGS line from

LDFLAGS = -g0 -lcxcore -lcv \
        -L../lib -lurob4o -lugen4o -lumap4o -lucam4o \
        -lpng -ldl -rdynamic -lcurses -lreadline -lraw1394 -ldc1394_control

to

LDFLAGS = -g0 -lcxcore -lcv \
         -L../lib -lurob4o -lugen4o -lumap4o -lucam4o \
         -lpng -ldl -rdynamic -lcurses -lreadline

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
  • drivebase.rule - The basis for (HAKO) missions - Drivebase.rule
• 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.
• mapbase.so.0 - a base plugin for mapped lines and connected graph of routes
• aumapobst.so.0 - converts near map lines to obstacle polygons Mapped obstacles
