rack5:xDR Challenge in Industrial Scenarios 2019


xDR Challenge in Industrial Scenarios 2019 (hereinafter referred to as xDR Challenge 2019) will be held as a sequel competition to "PDR Challenge in Warehouse Picking" at IPIN2017 and “xDR Challenge for Warehouse Operations 2018” at IPIN2018. This year’s competition will be held as IPIN2019’s official competition track (track5). The competition is an off-site tracking competition by sharing sensor data measured in actual industrial fields. The aim of the competition is to encourage the researchers to develop the xDR algorithms which can be utilized for realistic industrial scenarios. The xDR Challenge 2019 will be hosted by PDR benchmarking standardization committee.

This year, we will change the target fields of the competition from warehouse to other fields. First, we selected a Japanese restaurant as a target. The restaurant is very unique because employees and dish delivering robots are collaboratively working together in the restaurant. Additionally, we also selected a factory in manufacturing industry as another typical types of industry. The operations of employees can be objectively analyzed for improving the operations by data-driven service engineering. The results of estimation by Indoor localization and action recognition are the most important inputs for the objective analysis.

In those scenarios, we will prepare two categories of the competition in the xDR Challenge 2019.

  • PDR based indoor localization track with a waist-mounted sensor
  • Action recognition track with body-mounted sensors

If you tell us an intention to join the competition, we can provide you previous competition’s dataset as sample data.

We look forward to your participation!

Call for Participation

Currently, we are accepting pre-admission.
We will provide sample data for those who completed pre-admission.
For pre-admission, please send following information to xDR-Challenge2019@aist.go.jp.

Pre-admission is a preliminary registration just for providing sample dataset and information.
We will open the real registration for the actual entry of the competition, when the actual datasets are ready for delivery.

Sample data and evaluation script

As described in the call for participation, we are providing sample dataset those who completed pre-admission.
As the sample data, we will provide you previous competition datasets with ground truth for now.
You can objectively evaluate your algorithm with the dataset for xDR Challenge 2018 and evaluation script uploaded on Github

Categories of the competition

This year, we will hold two-separated-sub-tracks in our competition

- Manufacturing track: Estimating trajectories of employees who work in a factory in manufacturing industries.  
In the manufacturing track, we utilized PulsarGum as BLE beacons. The PulsarGum is battery-free beacon. BLE signals are emitted disproportionally, and dependent of the condition of photovoltaics.
The shortest interval of the BLE signal emission is 1.26 sec. The sensor data used for the competition is measured by BL-02.
A typical image of the target factory is shown in Fig. A.
How to carry the device is shown in Fig. B. Floor plan of the manufacturing track is shown in Fig. C.

- Restaurant track: Estimating trajectories of employees who work in a Japanese restaurant together with food delivering robots. Action recognition is also planned to be included.
In the restaurant track, we utilized BLE beacons by Aplix and Nexus 5 for sensor logging.
They are same as used in the xDR challenge 2018.

Useful Reference

If you want to learn about basic of PDR,
We suggest you to learn from very valuable PDR tutorial by Antonio R. Jiménez at IPIN 2017.
You can download tutorial slides and sample PDR code and sensor logger from

PDR code authored by LOPSI group at Centre for Automation and Robotics (CAR), CSIC-UPM, Spain.

Sensor data contained in competition dataset are measured with similar sensor logger introduced in the tutorial.

Note that the way to carry sensor devices will be different with the tutorial. The sensor devices used for this competition are mounted on waist or stored in chest pocket.
