KTH Scitos G5 robot - Rosie

2D Map with waypoints

The data was collected autonomously by a Scitos G5 robot with an RGB-D camera on a pan-tilt, navigating through the KTH office environment over a period of 7 days. Three waypoints have been defined on the 2D map, and each one is visited once per day. Each observation consists of a set of 28 RGB-D images obtained by moving the pan-tilt in a pattern, in increments of 60 degrees horizontally and 30 degrees vertically. The data is a part of the Strands EU FP7 project.

Observations acquired by the robot

Dataset structure

The data is structured in folders as follows: YYYYMMDD/patrol_run_YYY/room_ZZZ, where:

  • YYYYMMDD represents the year, month & day when those particular observations were acquired. Each such folder contains the patrol runs the robot collected on that specific date.
  • patrol_run_YYY represents one of the patrol runs collected by the robot.
  • room_ZZZ represents a particular observation collected during a patrol run.

Each folder of the type YYYMMDD/patrol_run_YYY/room_ZZZ contains the following files:

  • room.xml - contains information relevant for the observation (described in the next section)
  • complete_cloud.pcd - the point cloud of the observation (obtained by merging the individual point clouds together)
  • intermediate_cloud*.pcd - ordered point clouds, each corresponding to an RGB and depth image acquired by the camera while conducting the sweep (28 such point clouds for each observation)

The room.xml file accompanying an observation contains the following (relevant) fields:

RoomLogName - identifier which associates the observation with the folder structure

RoomRunNumber - identifier which denotes when the observation was acquired during the patrol run (i.e. 0 - first, 1 - second, etc.)

RoomStringId - identifier which corresponds to the waypoint at which the observation was acquired.

RoomLogStartTime / RoomLogEndTime - acquisition time

Centroid - observation centroid in the map frame

RoomCompleteCloud - complete cloud filename

RoomIntermediateClouds

RoomIntermediateCloud - intermediate cloud filename

  • RoomIntermediateCloudTransform - transform from the RGB-D sensor frame to the map frame, as given by the robot odometry

Parsing

A parser is provided here (can be installed with `` sudo apt-get install ros-indigo-metaroom-xml-parser``) which reads in the data and returns C++ data structures encapsulating the low-level data from the disk. Form more information please refer to the parser README ( or here for a list of supported methods). Information about how to use the Strands package repository can be found here.

Download

This dataset is available for download in a single archive file (~ 12 GB). As an alternative, the individual folders and files can be obtained from here, and would have to be downloaded manually.
