Mapbase

Revision as of 09:46, 5 September 2011

The mapbase plugin were created for the masters thesis Mission Management for Mobile Robots by Anders Beck. http://www.elektro.dtu.dk/English/research/publications_elektro.aspx?lg=showcommon&id=246287

Part of the thesis is reproduced here:

Mapbase on-line functions

The on-line commands for mapbase is (with some maps from the Tåstrup environemnt loaded):

>> mapbase help
>> <help subject="Mapbase">
--- available Mapbase options
help             This message
mapload=[file]   Loads data in file into database
graphload=[file] Loads graph data into database
export           Exports the entire map in XML format
mapLines         Export map lines
list          Display current contents of database
status:  has 77 nodes, 486 edges, 25 lines, 0 points
current node = 'taastrup' at (708000.00x, 6174000.00y, 0.0000h)
</help>

In addition some inter-plugin variables and function calls are available.

>> var mapbase
>> <help subject="var list" name="mapbase">
Description:                  Database for maprelated information.
  connMapPose=0 0 0          Return value of Connetor mappose

  edge(ss)                   Get feature value from [s] extracted from the edge name
                             [s]. Syntax: (edgename,featurename)
  node(ds)                   Get feature value from [s] extracted from the node id [d]
  node(ss)                   Get feature value from [s] extracted from the node name
                             [s]. Syntax: (nodename,featurename)
  connector(ds)              Get feature value from [s] extracted from the connector id

                             working properly, if unknown connectorname is entered)
  getConnMapPose(s)          Get the mappose of a connector (returns in var
                             connMapPose)
  addMapLine(sdddddd)        Add a mapline to current reference node. Parameters are
                             addMapLine("name", startX, startY, endX, endY, radius,
                             isObstacle). If isObstacle==0, then line is for localizer
                             only. Coordinates are in map coordinates (see graph for
                             position of node).
(H: has time series, L: is logged, R: replay)

Load a map

The mapbase was loaded and configured with this part of the aurobotserver .ini file:

...
module load="mapbase.so.0"
mapbase mapload="./apple_cherry_map.xml"
mapbase graphload="./apple_cherry_graph.xml"
...

Map definition

An example map is listed below (the cherry orchard in KU-Life Tåstrup):
