RoboCup Logistics Software Stack Release 2016

RCLL 2016 Simulator Screenshot The Carologistics RoboCup Team has released their software stack of 2016 based on Fawkes 1.0.0 for the RoboCup Logistics League. It is a continuation of the release last year. It includes, for example, direct communication with the Robotino for time-stamped and faster data access and many improvements to the basic skills of the robot, tooling, and simulation integration.

The following video shows the RoboCup 2016 finals between the Carologistics and Solidus. The released software stack is the one used by the Carologistics team, which won the competition.

Details about the release and a video of the simulation are available on the RCLL software stack 2016 release page.

Carologistics win third-in-a-row RCLL title

In a breath-taking final, the joint team Carologistics from RWTH and FH Aachen was able to defend their title against team Solidus from Switzerland with 94:26. This is the third championship in a row that the team won in the RoboCup Logistics League at the international RoboCup competitions . The team consists of researchers and students from the Cybernetic Cluster (RWTH Aachen, Mechanical Engineering, Prof. Sabina Jeschke), the Knowledge-Based Systems Group (RWTH Aachen, Computer Science, Prof. Gerhard Lakemeyer) and the MASCOR Institute (FH Aachen, Electrical Engineering and Information Technology, Prof. Alexander Ferrein).

In the RoboCup Logistics League two teams compete with three autonomous mobile robots each in an intra-logistics scenario. The scenario reflects the idea of an industry 4.0 setting, where intelligent machines take over building complex products in a dynamic production process. First, robots have to explore their environment to locate and identify the machines available. Then, an optimal flow of material using these machines is planned and realized.

This year again a technical challenge was held. It features taks alongside the main competition to test possible future developments of the league. One goal amongst others was to locate the modular production stations without the help of markers (e.g. QR or AR tags). The team Carologistics was able to reach first place in this challenge as well. Apart from this challenge, for the first time, a RoboCup Industrial Cross-Over-Challenge was arranged. In this challenge teams from the RoboCup Logistics League and from RoboCup@Work collaboratively work on a common task. The Carologistics team already published their software in 2014 and 2015 and they were awarded the third place of the 1st International Harting Open Source Award.

Besides their strong basic capabilities in environment perception and navigation the robots from the Aachen Carologistics team scored with their robust decentralized multi-agent strategy. This strategy is particularly fitted for highly complex, only partially known and dynamic environments. After a convincing preliminary round and playoff-phase the Carologistics had to face team Solidus from Switzerland in the grand final. With a strong performance the Aachen robots were able to clearly secure their victory. This also reinforces Aachen's current role as a leading place for science and research in mobile robotics and artificial intelligence.

Next year, after 21 years RoboCup will be held in its birth place Nagoya in Japan again, where was held for the first time in 1996.

Robocup 2016 in Leipzig - the story begins

We made it to Leipzig yesterday. After watching the germans reach the quarterfinals, we enjoyed the beatiful sunset at our lake. Today we did a sightseeing tour through Leipzig by Bus and visited the very impressive Monument to the Battle of the Nations called 'Völkerschlachtdenkmal'. Now we are back to hacking at the lake...

Successful Winter School

RoboCup Logistics League Winter School Group PhotoFrom December 7th to 11th, the Carologistics Team organized the first RoboCup Logistics League Winter School in Aachen, Germany. Participants of new and existing teams from Germany, Austria, and Japan attended the event. The winter school was held to help new teams to start into the league and existing teams to adapt to the invasive rule changes performed in the past few years.

The content was based on the (pending) full 2015 software stack release of the Carologistics team to better understand and tackle the problems of perception, navigation and self-localization, using and extending the RCLL simulation and the behavior sub-systems like the Lua-based Behavior Engine and the CLIPS agent.

The winter school was supported by Festo Didactic SE and the RoboCup Federation. The feedback of the participants was very positive and the team enjoyed sharing and discussing ideas with the RCLL community at large!

We are currently preparing the material and will release the videos of the talks in January. The slides and information material can be found on the winter school wiki page.

RoboCup Logistics League Winter School 2015

The RoboCup Logistics League (RCLL) is one of the youngest of the RoboCup leagues. It is an application-driven league inspired by the industrial scenario of a smart factory. In 2015, the introduction of MPS processing stations and increasing the number of possible products from 3 to nearly 240 has made the RCLL more complex and challenging.

The Carologistics RoboCup team, which won the competition in 2014 and 2015, intends to organize a RoboCup Logistics League Winter School in Aachen, Germany. The purpose is to disseminate the state of the art in the RCLL. This winter school targets new and existing teams for the RCLL. For new teams it will lower the barrier to enter the competition by learning from an existing open-source software stack and simulation. Theoretical sessions will detail the applied methods in fields like perception, navigation, simulation, or behavior. This will be be supplemented by practical hands-on sessions.

More information and a link for the registration is available on the RoboCup Logistics League Winter School 2015 page.

Bonding Hackathon 2015

Together with Bonding we hosted the Bonding Hackathon for the third time in a row. 47 students split up in small teams and hacked through the night.

The scenario was a nuclear catastrophe and the teams had to bring nuclear fuel rods from the reactor to some decay tanks. They got points by successfully delivering a fuel rod to a decay tank. The decay tanks were hidden and randomly placed on the field. We also placed random obstacles on the field. The better the tanks were hidden the more points you got, from 1 to 3 points. The tanks and the reactor were identified by AR-tags. The teams had to rescue 3 fuel rods, so there were different strategies. Either to find the 3 point decay tank, which is hard to find, or just use the 1 point decay tank. The scenario was represented in our simulation based on gazebo, so the teams could run through a lot of testing cycles, before testing on the real hardware.

We offered the students first-hand knowledge and experience in robotics, whilst Bonding took care of them with free food and soft drinks during the whole night.

The sponsors (Bosch, Continental and IVU Traffic Technologies) provided some exiting prices for the top 3 teams. The first place won a trip to the Bosch ConnectedWorld Conference in Berlin. Alltogether it was a great event and we look forward to next years Bonding Hackathon.

Here are videos of the final and the winning teams skill in the simulation:

We won Robocup 2015 in the Logistics League!

We won Robocup 2015 in the Logistics League! Although having some problems during the first games of the competition we were able to stabilize our exploration for the final and even managed to deliver products correctly. Team Solidus proved to be a worthy opponent and achieved only 8 points less in the exploration phase (you get 8 points for one explored machine). The end result was 46:16 for Carologistics.

The new setup with new machines turned out to be a big challenge and we hope to speed up our production for the next year. But for now we will celebrate the first place before returning to Germany on Friday.

Winner German Open 2015

The Carologistics RoboCup team was successful again this year at the RoboCup German Open 2015.

This year, the league used actual processing stations based on the Festo Modular Production System (MPS) for the first time. Additionally, the machines were placed freely within certain zones on the field (therefore neither the exact position nore orientation was known before the game) and the number of product variants increased from 3 to almost 300. This made several adjustments necessary to the robot teams as well as to the referee box, the program controlling the environment and machines during the game.

By the end of the tournament we were able to almost complete the exploration phase with only a single machine missing. The robots then executed the first steps for the production phase, but eventually failed as the handling of the machines was not yet precise enough. The robots coordinated to use the stations in the proper order, but the products were not placed properly on the conveyor belt. This is a challenge we will work on on the way towards RoboCup 2015 in Heifei.

Let me introduce the Carologistics Robotino GO2015

In 2015, the robots have to handle pucks at working height of humans. Therefore, we switched to the new Robotino Version 3. Robotino 3 can handle higher payloads and has better hardware-interfaces for mounting components.
The following image shows our Robotinos including some modifications:
Carologistics Bot GO2015 For further computation power we added a Lenovo Thinkpad X230. The dualcore on the robotino platform is running an Ubuntu Linux and is responsible for hardware interaction (actuators, sensors). On the lenovo, the high-level components such as the behavior engine and our task-level reasoning agent as well as the computer vision components are running on fedora F20. As a middleware, the robot framework Fawkes is used on both robotino platform and lenovo notebook.
For collision avoidance, localization and wall alignment we use Sick Tim5xx LaserScanners. The LaserScanner were a donation from the Sick Sensor Solutions (thank you so much -again). The detection os AR-tags is done with simple Logitech Webcams mounted to the beam of the robotino. A second logitech mounted on top is used for detection of signal lights. To guarantee fixed angles we use serrated locking plates from Ganter Griff.
For grasping cylinders, we developed a gripper, following the example of our fellow RoboCupers from Liverpool. The gripper uses Dynamixel AX12+ motors and Fin Gripper Finger from Festo. The grippers enable us to cope with lateral offsets of the cylinders due to inexact positioning.

First days @ GermanOpen 2015

Its Thursday evening - the second day of the German Open 2015. The last two days were intense. The integration of the software components took a lot of time - as always. And there is still way to go.
We are currently focusing on the exploration phase of the Logistics League Competition. In the exploration phase, the robots have to explore the factory area, detect machines and perceive the type of the machines by reading AR-tags. Our current progress can be seen in the following video.

The video shows two robots exploring the machines on the right side of the competition area. The two bots are exploring, far slower than we expect them to do. But a lot of tuning and skill optimization will help.
One robot crashes after a while. The other one shows a good behavior in passing a narrow passage to read the AR-tag on a machine. This takes a lot of time but its a safe drive. All in all, it seems that we are on the right track. The next days will show ;-)
Our first test-match will be tomorrow at 12:00 o'clock against the colleagues from france. We hope to score some good points.

Day before GO2015

After weeks of preperation, Team Carologistics is now in the final test phase for GermanOpens in Magdeburg.
The last weeks have been intense. As we - again - started late with preperation, we now have all componets together for integration - at least most of the components. The rules of Logistics League have changed massively since last year. Thus, our system needed to be restructured and extended.

The major difference between 2014 and 2015 is that we now have to grasp objects and have to deal with a changing settings of the playground. The small pucks which were used as products in 2014 changed to be small cylinders in 2015. The teams have to grasp the cylinders from shelves and transport them among small production machines (that are called MPS - Mobile Production Station). The MPSes are randomly placed in the production area. Therefore, we developed a gripper and a lot of software for interfacing the gripper, recognition of cylinders, signal lights, ar-tags and a generator of a dynamic topological graph. Now, final test are running. We'll see if the components fit together in Magdeburg.

Right now, the tools and other stuff is packed and the busses are booked. Our Accommodation will be Ferienpark Plötzky - again. We are looking forward to a great event in Magdeburg....
