Round Robin/ Playoffs (Day 2)

Day 2 of the Festo Logistics League is finished. The round robin phase concluded after the first 2 games. We won the first game versus the Bavarian Bending Units from Germany with 90-65. The Second game versus the team RBQT from France we won 91-10. We still had to face problems regarding low level skills and some vision problems. Because of that we threw away some final products and stopped productions.

But apart from the lower level problems the top level agent behaviour always knew the right thing to do. Our system could handle the problems and detect possile solutions autonomous. Because of that we finished the group stage as group first!

In the afternoon the playoffs started. It is organized in a group - the first 2 teams will play the grand final, the 3rd and 4th will battle for 3rd place. In the first game of the playoffs we won 109-10 versus the local team All Sparks from Brazil. The next game versus team Solidus from Switzerland we won 120-13.

After the games we attented in the MPS challenge. With a dynamic approach to the problem we also won this technical challenge. Read and see more about it in the official blog post.

More and more little but very important failures are getting fixed and so we are going confident into the second day of the playoff.

Carologistics win the MPS Challenge

The task of the MPS (modular production system) technical challenge was to approach a shelf, pickup a container, take it to the machine which places a cap on top, pick it up on the other side and take it back to the shelf. Similar machines will be used next year for the RoboCup Logistics League.

The task was solved by a dynamic approach to detect the ARTags on the shelf and the machine for an exact alignment.

Round Robin (Day 1)

Day 1 of the round robin phase of the Festo Logistics League is finished. The first game versus Team Solidus from Switzerland we won 80-18. The second game versus Team Baby Tigers from Japan we won 101 to 10. But we have to say these results don't really show the big problems we had in the games. One reason was a really disrupted light detection because of the sun shining through the colored flags which are hanging in the venue. Also some low level skills had some minor erros which obviously have a big effect on the whole game. And because of that we couldn't perform as well as in the training games on the setup days.

After the games we attented in the navigation challenge. It was a happy end of the day, because we won the challenge! Read and see more about it in the official blog post.

After the challenge the field was free for all the teams to fix the problems and test them. The vision got tuned and we also found some bugs in the skills and agent. We only had a small time frame to test the whole system because the last busses are leaving the venue at 11pm. So we have to see in todays games if the whole system will perform better to qualify for the playoffs.

So keep the fingers crossed and stay tuned to the blog. You can follow our twitter hastag at #Carologistics. LIVE results of the games can be found here.

Carologistics win the Racing Challenge

The Carologistics won the racing challenge showing quick motions and capable collision avoidance. This is a new aspect introduced into the game this year by putting two teams on the field. This additional technical challenge then brings in a focus on speed while still avoiding collisions. Teams are increasingly implementing the necessary changes. The Carologistics had a head start being able to re-use existing code from the AllemaniACs RoboCup Team and extending it for holonomic drive and tuning it for quicker stops at higher speeds.

Below are videos of the challenges from the robot's and from the spectators perspectives.

RoboCup 2014 - Setup Phase

The first two days of the RoboCup are reserved as setup phase for all participating major teams. On arrival at the venue or robots were still sitting in their transportation boxes and had to be assembled. Luckily the hardware survived the the flight, shuttle transport and especially the customs without any damage. Additional spare bots and the batteries were shipped by FESTO via container. Out of ten batteries only two did not survive. Since we are playing with three robots plus one for one of the technical challenges, we had the two required batteries for each robot.

After using the first morning for robot assembly, first test drives were made during the afternoon. Although the first test game was promising, a lot of improvements still had to be implemented. Everytime the conditions in the venue are different. This time for example there are a lot of colored flags at the walls, which disrupt the light detection heavily.

But we are on it to fix all those problems for a succesful playoff phase.

RoboCup 2014 has begun

The RoboCup 2014 is taking place in Joao Pessia, Brasil. 10 teams are battling for the Cup in the Logisitics League sponsored by Festo. Two teams are from Germany - The Bavarian Bending Untis from Munich, and ourselves, Team Carologistics from Aachen. Besides that, 3 teams from Brazil, one from Japan, Egypt, Mexico, Switzerland and one from France. As strong changes have been made to the rulebook as well as the playground - the cards are re-shuffeled. (Please see the official league homepage for more details.) This year, the teams have to show that their robots are able to avoid collisions and track their own position on the large playground. As most teams have relied on odometry only to track their position and followed predefined paths without collision avoidance this means a large challange for them.

Stay tuned for more infos on this Blog.

Campus52 TV snippet about the Carologistics

The Campus52 campus TV has created a short documentary about our preparations for the RoboCup 2014 competitions in Brazil. We think it's great and thank them for their efforts!

We have now arrived and are preparing in the hotel in Joao Pessoa. You can find a flow of posts about our progress on Twitter with the #Carologistics hashtag.
