We also have a few new journal publications:


MBZIRC robotic challenge victory

Our team (also Uni Lincoln and UPenn involved) led by Martin Saska won the Mohamed Bin Zayed International Robotic Challenge (MBZIRC) – Challenge 3 that required a team of UAVs to collaborate to search, locate, track, pick and place a set of static and moving objects. The team also took 2nd place in Challenge 1 – landing on a moving platform and 3rd in the Grand Challenge – after joining University of Padua.

Center successful in securing new funding

CRAS members were very successful in securing new funding from the Czech Science Foundation. The following three-years projects start 01/2017:

  • K. Zimmermann. Robust motion planning and control on rough unstructured terrain.
  • M. Hoffmann. Robot self-calibration and safe physical human-robot interaction inspired by body representations in primate brains
  • M. Saska. Stabilization and control of teams of relatively-localized micro aerial vehicles in high obstacle density areas
  • M. Saska. Methods of Identification and Visualization of Tunnels for Flexible Ligands in Dynamic Proteins
  • T. Krajník: Spatio-temporal representations for lifelong mobile robot navigation

Our robots helps with mapping of historical monuments


Scanning of historical buildings with inaccessible areas is difficult task for archaeologists and restorers. Members of CRAS from Multi-robot Systems group (MRS) help with scanning of such inaccessible areas using their own drones.
At February 26, MRS together with National Heritage Institute in Olomouc scanned the church in Sternberg. During the scanning of high placed areas such as copula and wall paintings, we used our methods for stabilization of autonomous helicopter formation.

Nowadays we negotiate with other heritage institutions to scan other historical buildings.

Participation in Mohamed Bin Zayed International Robotics Challenge

Team of Czech Technical University in Prague, University of Pennsylvania and University of Lincoln, where members of CRAS play key roles, has been selected for gaining sponsorship for participating in the Mohamed Bin Zayed International Robotics Challenge (MBZIRC) out of 143 applicants from the most prestigious universities in the world. The international team, which is led by Martin Saska,  will compete with the worldwide best universities in the field of Micro Aerial Vehicles (MAV) in two Challenges. The first is to autonomously localize a moving vehicle in the arena by a single MAV and then land on a landing platform carried by the vehicle. The second Challenge is to search the arena for various static and moving color objects, then pick them and move them to dedicated area. For more information about our participation in MBZIRC see sites of Multi-Robot Systems group.
