Bronze for Aachen’s Carologistics at the RoboCup Logistics League World Championship in Montreal

The team Carologistics, consisting of scientific staff and students of the Cybernetics Lab IMA & IfU, the Knowledge-Based Systems Group (both RWTH Aachen University) and the MASCOR Institute (FH Aachen University of Applied Sciences), came in 3rd place in the RoboCup Logistics League in Montreal on 21.06.2018.

Throughout the tournament, the Carologistics repeatedly struggled with Wi-Fi problems. After the robots did not move, because no communication was possible, all WLAN components were exchanged. The new hardware led to a strong delay and the robots were only minutes later that the game had already started.

Despite the adversities, the team gave everything and was able to work its way forward in the tournament until they were stopped by the new world champion from Graz, who they had defeated in the finals of 2017. The small finals were won by Carologistics, achieving third place in a league that makes major technological leaps every year and shows more and more of what will be possible in the so-called "Smart Factories" of the future.

The RoboCup Logistics League is characterized in particular by the fact that here on a 14 x 8 meter large playing field is shown on a small scale, which in the next few years in so-called "Smart Factories" in Industrie 4.0 context from an intralogistic point of view is possible. So the robots of each team have to explore the playing field and report back which position is which machine. Thus, the robots themselves find the best connections between individual machines. When this first phase (exploration) is completed, in the subsequent production phase it is a question of manufacturing individual products of lot size 1, ie the robots are informed of time slots for orders for products, from which the collective of robots decides when and how Order produced. At the same time, the production process must be broken down into its individual components and interdependencies. This results in tasks with temporal dependencies, which the robots must divide among themselves.

Carologistics defend the championship title at the RoboCup German Open Logistics League

The Team Carologistics, which is composed of researchers and students of the Cybernetics Lab IMA & IfU, the Knowledge-Based Systems Group (both RWTH Aachen University), and the MASCOR Institute (FH Aachen University of Applied Sciences) successfully defended the German championship title in the RoboCup Logistics League for the fourth time in a row. The RoboCup German Open took place from 25 to 29 April at the Magdeburg exhibition halls.

After an exciting group phase, the Carologistics started into the playoffs leading with 106 points, one point ahead of the runner-up GRIPS from Graz University of Technology. After the playoffs, both teams faced each other again in the final.

In the final against GRIPS, also the runner-up of last year's international RoboCup, the game was extended by an overtime of 5 minutes for the first time in the history of RoboCup Logistics League because both teams were tied at the end of the regular game. The Carologistics then took the lead by two points and kept it until the end of the game. At the end of the game, they could almost score another two points, but - as in the World Cup in Japan - the final action was finished one second after the end of the game and so the game ended with a narrow lead of Carologistics.

In the RoboCup Logistics League, two teams compete with up to three autonomous mobile robots in an intralogistics scenario against each other. The playing field is a smart factory from the context of the Industry 4.0, where intelligent machines manufacture complex products in varying production environments.The scenario is particularly characterized by the comprehensive communication and cooperation of the mobile robot. In the first phase of the game, each robot team explores the previously unknown playing field, creating a common "world view". In the second phase, the electronic referee (RefBox) announces complex products that must be produced cooperatively within certain time-windows. In this phase, the robots have to re-plan frequently, as the opponent plays on the same field and therefore the accessibility of paths or machines is always subject to variations. Machines spontaneously switch to a maintenance condition and can not be used at this time, and because individual steps such as grasping a product may fail occasionally.

In preparation for the RoboCup World Championships in Montreal, Canada in June, the team will focus on improving the gripper system to allow more robust autonomous grasping of work pieces in order to make full use of the newly developed agent system.
