Contents
This package can also be used as an (advanced) example for using the C++ sql database interface. A simpler example is provided in the database interface tutorials.
This database is mainly used by our manipulation pipeline, which is described in detail on the object_manipulator package page.
Overview
The household_objects_database is a thin C++ and ROS wrapper for an SQL database used for recognition and manipulation. Its main role is to
- provide C++ data types for the data contained in the database;
- provide easy to use C++ functions for the the most commonly used queries;
- provide a ROS node wrapper for the most commonly used data queries so that they are accessible over ROS topics or services.
The Database
For a detailed description of the database itself as a SQL entity, its schema, the data that is contains and the design decisions behind it, see the household objects page.
ROS Node Wrapper and ROS API
The ROS node wrapper provides some of the most common database queries as ROS services. It requires the following node parameters on startup to establish a connection with the database server:
/household_objects_database/database_host: the address of the database server
/household_objects_database/database_port: the port to establish the connection on
/household_objects_database/database_user: the database username
/household_objects_database/database_password: the password for the database username
/household_objects_database/database_name: the name of the database to connect to
Once started, the wrapper node provides the following ROS services:
GetModelList: retrieves a list of models available in the database
GetModelMesh: gets the 3D mesh for a given model
GetModelDescription: gets a set of descriptive meta-data for a given model
GraspPlanning: retrieves a list of database grasps for the given model. In order to provide this service, the node will also look on the parameter server for a description of the arm being used. See the pr2_object_manipulation_launch package for an example of this description.
In general, information about database objects recognized in the robot's environment are passed around the system in the form of DatabaseModelPose messages.
Using the Database
Install the database on your local machine
You can download a database backup file and install it on a local database server. Has the advantage that the database is local and can be modified. Here is how you can do it:
install a PostgreSQL server on one of your machines
install the household_objects database on your server.
Remote ROS access to database hosted at Willow Garage
Note that remote read-only access to a server hosted at Willow Garage is no longer officially supported. The infrastructure is still available, but the overhead of keeping the ROS wrapper always up at Willow ended up being too high.
If you'd like to set up that service for yourself, the documentation for the client side is still at tutorial for remote use of the database.
