RoboCup Germany 2016

Posted Posted in News-en

This year, too, the WF Wolves RoboCup team from Ostfalia will compete at the World Championship for Robotics. This year the World Cup in Leipzig takes place from the 30.06. To 03.07.2016 instead. The team of the Ostfalia is in the categories RoboCup @ Work and Humanoid League (TeenSize). As in the past year, the students are working with their Brazilian colleagues at the Universidade Federal de Santa Maria (UFSM).

The current Leipzig team consists of 14 members. Five team members come from the Brazilian university. The WF Wolves are supported by professors Reinhard Gerndt (Ostfalia) and Rodrigo Guerra (UFSM) as a student project group.

Already since Monday, the students work to find the optimal setting of the robots for the conditions.

The RoboCup @ Work League:

The @work league is an industrial league. On the other hand, autonomous platforms, on which a robot arm is located, must successfully meet certain challenges. These challenges consist essentially of mastering a pre-defined course. As a particular challenge, its details can be varied in the course of the process. In addition, various, different objects have to be picked up by means of the robot arm and transported to a different location.

 

The Humanoid League (TeenSize):

In the Humanoid League, on the other hand, it is about football. At the same time, robots that are built similar to humans are played together according to the rules of FIFA. The aim of the Humanoid League is to compete against the then reigning FIFA world champion of the people in a regular football match in 2050.
In the Humanoid League, three sizes of robots are distinguished: KidSize, TeenSize and AdultSize. The sizes range from very small to almost man-sized. The team of the Ostfalia has medium-sized robots and plays in the TeenSize.

 Humanoid League

Everything started with our luggage hanging in Guangzhou. So we did not just lack robots and equipment, but above all clothes for changing after the long journey. What remained to us was the hand luggage, with which we had at least one or the other, if of course no tool. In the hotel we met our partners from Brazil, who had arrived with two robots. On the first day of preparation we still missed two of the big robots, which we could not prepare. The first one, which had arrived, we did not get through the robot check until the head was too big. It was measured differently than in the previous year, which caused problems not only with us. So we had to cut our head, which looked ugly and also led to more instability. Even the Brazilian comrade had to take off his helmet and was not allowed to play with it. While the Brazilians were working on the new running algorithm, our people were in the process of calibrating the recognition of objects. But the time that remained was short and was not enough. While the recognition of the playing field and the goal post worked well, especially the search for the ball of the Teen Size brought unimagined problems. This involved neglecting running and shooting, which led to frequent falls in the games.

 

In the Kid Size, we were in group B with ZJUDancer and FUmanoids, which did not allow us an easy start. The final result of the group phase was then no surprise. In the intermediate round we had once again the chance against RoboErectus, where our robots unfortunately could not get through. In Teen Size, we had similar difficulties and could not score goals. Overall the competition was stressful for us because we had one game after another by participating in both leagues. It was noticeable that we were short of specialists and robots. In the Technical Challenges, however, we were once again able to prove what our robots are capable of doing. They could not only jump surprisingly high, but also balance large shocks of the push recovery. We were able to secure second place in both leagues.

German Open 2015

Humanoid League

This year’s German Open was a little spectacular, but with many challenges on the ground. By the new rules – artificial grass, a new white-colored ball and white gates – the robots demanded everything. We were with two small and two large robots at the start, could because of unexpected problems with the hardware but unfortunately only partially one or two at the same time. The initial round robin phase went all dead, finding the ball and then moving to the ball was difficult not only for us at first. Then we came to the Penalty Shootout, where we secured fourth place. It was followed by the semi-final against the Fumanoids, which went 1: 0 for them, so we came into the game for the third place. In this game, we were able to show that we can not only run stably, but are even capable of shooting shots without adding. Nevertheless, all the arts were not enough for a goal during the game, it went 0-0. In the following Penalty Shootout our robots had the problem of recognizing the ball and running past the ball again and again. In the last attempt, our opponents, Bold Hearts, were able to move the ball a little way forward while we have not reached the ball. This was ultimately the decision and the fourth place for us. The German Open has revealed some weaknesses and allows us to prepare ourselves for the World Cup in China.

RoboCup Brasili 2014

Posted Posted in News-en

(By Prof. R. Gerndt)

The Eastfalia was represented by a team of 10 students who were reinforced by 4 students from our partner school in Santa Maria, Brazil, the Universidade Federal Santa Maria (UFSM).

In the ‘Humanoid League’, the Ostfalia after the preliminary round (1. ‘Round Robin’) by a single own goal in the first knockout round. Apart from general problems in the preparation, the delayed delivery of a suitcase with numerous tools also caused problems. The goal to get into the second round (2nd ‘Round Robin’) was missed. The team has, however, for the first time participated in some ‘Technical Challenges’ and was able to score points. On the RoboCup2014, a new, larger robot and a robot equipped with elastic knee drives (Series Elastic Actuator – SEA) were also used for the first time.

The RoboCup @ work team had to deal with hardware and software problems. Already at the beginning of the competitions, for example, the gripper had failed and had to be replaced by a loan from another team. In addition, the “Conveyor belt challenge” had to be omitted for technical reasons, which brought additional disadvantages to the team, who could last this test as the only team. The goal of 1000 points in the competitions (approx. Third place) was not reached with about 680 points.

At the RoboCup Symposium (http://www.robocup2014.org/?page_id=27) Ostfalia was represented with a research project on “Series Elastic Actuator”, which was jointly funded by the UFSM. The importance of the topic was underlined by the two invited lectures by Prof. Brooks (MIT) and Prof. Haddadin (Leibniz University). The response to the Ostfalia contribution was correspondingly large. The topic is to be pursued intensively.

In the run-up to the RoboCup is a contribution for the NDR television (http://www.ndr.de/fernsehen/sendungen/hallo_niedersachsen/Fussball-Roboter-wollen-Weltmeistertitel-holen,hallonds22546.html). The SEA robot was mentioned in the heise-newsticker (http://www.heise.de/newsticker/meldung/RoboCup-WM-2016-kicken-die-Roboter-in-Leipzig-2264401.html?hg=1&hgi=4&hgf = False).

The contribution of the Ostfalia to the further development of the RoboCup was recognized. Mr. Hitzmann was confirmed as a member of the Organizing Committee (OC) for RoboCup2015. Prof. Gerndt has been appointed to the executive committee (‘Exec’) for the ‘Humanoid League’ (for the structure see http://www.robocup.org/organization-of-robocup/).

In all, a number of contacts were made. The team has received invitations to study stays and cooperation with other universities. The SEA research project is to be expanded further in a close cooperation between Ostfalia and UFSM.

Unfortunately, our humanoid robots were eliminated yesterday by an own goal from Arctos with 0: 1.

After the last game, Lupo’s leg had to be repaired. Unfortunately, due to other problems we had too little time to test, where he could still run and shoot. Unfortunately, his shot from the left flank was a bit of a pain, but he stayed up unsuccessfully without a problem.

After the game, the team needed some encouragement before it started the preparations for the Technical Challenges. This is why we have created the emergence of our large humanoid robot. After he got up like our little humanoids, we went on with the walk (Oliver had already programmed it). In the test on the normal playing field the walk was already very good, so we went directly to the field with artificial grass. There, too, the robot could run to our delight.

20.07.2014

On Friday, we arrived at João Pessoa after three flights and welcomed the Brazilian students Leandro, Milton and Fernando into our group.

Unfortunately, one of our suitcases has been missing since the last flight. Since it is the humanoid toolkit (including cold sprays, multiple sockets and keyboards), Benny and Milton had to try to buy some work tools, and the teams were able to use the existing tools. This worked well, so that the loss of the cold spray is the biggest loss since we can not buy this on the spot.

Despite these slight difficulties, the humanoids were able to successfully use the first setup day and the four small humanoid robots were almost finished in the evening. In our apartment were still a few popped errors of the software, which was played this morning on the robots.

 

As can be seen in the picture above, the humanoids have been able to continue working on their large robot. This morning he was allowed to play for the first time in Brazil on one of the football fields.

With our @ WORK team ran yesterday the arm not, but after a day of hard work and with the help of an older version, we have not only fixed this, but started to optimize a lot. This includes, for example, an acceleration of the arm’s alignment with objects. Our goal is to arm the YouBots arm more than twice as fast!

In the sense, the team says thank you!

New Humanoid Robots from Eckensberger Foundation

Posted Posted in News-en

Today we have received information from the Eckensberger Foundation: They sponsor us in the creation of two new humanoid robots. We are very pleased with this support and have immediately ordered the components. The new humanoid robots will be bigger than our current ones and we hope that we can take one of the two new robots to the World Cup to Brazil.
