(By Prof. R. Gerndt)
The Ostfalia 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’.
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.
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!
