All data are in universally usable formats, such as plain text files or .png images.

We know that especially rosbags are valuable to the community. We already uploaded specific rosbags to our sever. However, to preserve space, we will upload additional rosbags only on request.

If desired, we can provide the original rosbag files. Please contact us separately regarding this request.


The callibration was done with:
DLR CalDe and DLR CalLab – The open-source DLR Camera Calibration Toolbox

The calibration files contain images of the DLR calibration pattern seen by all cameras. The calibration images are found on the download page, together with the calibration results.

Provided files:

  • raw images of the calibration pattern
  • calibration results
  • calibration information on the rectified images

Go to the download page to access the calibration data:


We use the SLAM navigation algorithms VINS-Mono and ORB-SLAM2 for navigation with MADMAX. You are invited to compare your navigation solution against these two algorithms.

The code: VINS-Mono on
The paper: VINS-Mono: A Robust and Versatile MonocularVisual-Inertial State Estimator

The code: ORB-SLAM2 on
The paper: ORB-SLAM2: an Open-Source SLAM System forMonocular, Stereo and RGB-D Cameras

The resulting navigation Data can be downloaded in the download section. The trajectories of VINS/ORBSLAM are shown for each individual experiment under „Location Details“.

The performance of the algorithms is shown here:

GNSS Ground Truth:

We computed the ground truth using our own algorithms. However, you can use the provided data of the left, right, and base antenna to compute your own ground truth. The provided raw data can be processed using RTKLIB:
RTKLIB: An Open Source Program Package for GNSS Positioning

Our GNSS setup is shown in the figure below (left). We use two antennas with a baseline of 1.285m to calculate the combined ground truth position and orientation of the Body frame B of SUPER, relative to the Topocentric frame T.

Our algorithmic approach to obtain the ground truth is shown below (right). Everything is described in detail in our paper.

Known Issues

Frame Drops

As discussed in the publication, errors with the Ethernet connection of the cameras caused drops of frames.
How much each experiment was affected is shown below.
Interestingly, our evaluation with ORBSLAM2 and VINS-mono did not establish any correlation between frame-drops and navigation accuracy / robustness.

Percentage of frame drops compared to overal number of frames.

Percentage of frame drops compared to overall number of frames.

Camera decalibration with the G-runs

During the G runs, the stereo camera intrinsics got decalibrated due to an mechanical impact. This results in slightly inaccurate depth images. SLAM based algorithms can usually handle this and provide correct navigation results.

Handheld field testing is representative for Rover navigation

As described in our paper (section 6.3), we conclude representativeness of our data set for planetary rover navigation, as the navigation algorithms have the same accuracy compared to similar Rover-based navigation data sets.


This work was funded by the DLR project MOdulares Robotisches EXplorationssystem (MOREX).

This activity has been conducted jointly with the two European Commission Horizon 2020 Projects InFuse and Facilitators. They received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No 730068 and 730014.
