"Mobile Manipulation, Tool Use, and Intuitive Interaction for Cognitive Service Robot Cosero"
appeard in Frontiers in Robotics and AI, vol. 3, 2016.
In the final, our robot Cosero demonstrated the use of tools. It grasped a dustpan and a swab in order to clean some dirt from the floor. Unfortunately, the dirt detection failed. The robot executed the cleaning motion and continued the demo by pouring out the contents of the dustpan into the dustbin. It placed the tools back on a table and continued the demo by starting to make caipirinha. For this, it used a muddler to muddle lime pieces. Our robot came in third in the overall ranking, behind Wright Eagle (China) and TU/e Eindhoven, Netherlands.
In the Coctail Party test and the Restaurant test, our robot had problems with object recognition and height estimation of the table, respectively. In the Demo Challenge, Cosero answered the door and received a package. He signed the delivery protocoll and carried the parcel with both arms to the user. We also demonstrated localization of objects tagged with Bluetooth low energy senders in the environment, which was instrumented with four receivers.
The Basic Functionality test went very well. Our robot Cosero demonstrated object recognition and grasping, navigation in the arena where an additional obstacle was placed and a door was closed, and question answering (speech recgnition and synthesis). In the Open Challenge, Cosero demonstrated the use of tools: It grasped a bottle opener and a bottle and opened the bottle. There was not enough time for picking a saussage from the BBQ, which we also had prepared. After Stage 1, our team NimbRo is leading the competition with 3756 points, followed by Wright Eagle (China, 3755 points) and TU/e (Eindhoven, Netherlands, 3401 points). In the Enduring General Purpose Service Robot test, our robot recognized two complex speech commands and carried out the requested actions.
On the first competition day, our robot Cosero handed out sweets to spectators in the Robot Zoo test. In the Follow Me test, Cosero learned the face of a human guide, followed it even though another person walked between the guide and the robot, went into an "elevator" with the guide and followed it out again, and relocated the guide successfully again after the guide went through a crowd of people.
Our team NimbRo@Home participates in the RoboCup 2014 @Home Leauge
competition in Joao Pessoa, Brasil.
Our team NimbRo won the @Home league of the service robots at RoboCup German Open 2014.
In the final, our robot Cosero demonstrated the use of tools. It opened a bottle and took a saussage from the grill. The robot also demonstrated bimanual grasping and transport of a tray. Our team reached a perfect normalized score of 100, followed byTech United Eindhoven (59 points) and ToBI (Bielefeld University, 50 points).
Our team NimbRo participates at the RoboCup German Open competition in Magdeburg in the @Home League. After Stages I and II, we are leading the competition with 7919 points, followed by Tech United Eindhoven (3611 points) and ToBI (Bielefeld University, 3069 points).
Our team NimbRo won the @Home League competition at RoboCup 2013!
In the final, our cognitive service robot Cosero demonstrated tool use. He used a pair of tongs to cook a sausage on the grill and a bottle opener to open a beer that he served to a person. This demonstration convinced the high-profile jury which awarded the highest number of points. Together with the results of Stage 1 and 2, the final normalized score was 99 points for NimbRo, followed by Wright Eagle (China, 86 points) and TU Eindhoven (Netherlands, 73 points).
Our robot Cosero performed two tests. In the Restaurant test, it followed a guide and learned a model of an unknown environment. It also used speech recognition to take orders. In the Demo Challenge the motto was health care. Our team demonstrated a handheld teleoperation interface. The robot also moved a chair to its location. Cosero also attempted to open a bottle with a tool.
Today, our robot Cosero scored in all three tests. In the Emergency Test, it guided a person who did not the way to the exit of the arena. In the Clean-up test, it found two objects and put one of them on its place. In the EGPSR test, it understood a complex speech command and fetched an object.
The highlight of today's Open Challenge was the demonstration of grasp transfer. Our robot Cosero registered a model of a known watering can with an unknown, different watering can. The non-rigid registration allowed to transfer grasp points and the tooltip position to the new watering can. Our robot grasped the can successfully with both hands, used it to water a plant, and placed the can back on a table.
Our team NimbRo@Home participates at the @Home League competition of
RoboCup 2013 in Eindhoven with the robots Dynamaid and Cosero.
On the first day, the robots went through inspection and registration.
Our team NimbRo@Home won RoboCup German Open 2013.
In the final, our robots Dynamaid and Cosero cooperated. Dynamaid
took an order, transmitted it over WiFi to Cosero who delivered a drink.
Cosero also pushed away a chair and Dynamaids delivered drinks and snacks to the jury.
Our performance received the highest score from bot the execs and the external experts. Together with our lead from Stages 1 and 2, we reached the maximal normalized score of 1, followed by SmartBots@Ulm (score .67) and team Homer (Univ. of Koblenz, score .61).
In the Demo Challenge, Cosero was teleoperated by an immobile
user who could command the robot navigation and manipulation on three
levels of autonomy using a tablet. Cosero fetched items and handed them
over to the user.
In the Extended General Purpose Service Robot test, Cosero had to understand several complex speech commands and to solve the requested tasks.
In the Restaurant test, Cosero followed a human guide and build a map of an unknown environment with marked object positions to which it navigated on spoken request.
After Stage 2, our team NimbRo is leading with 6297 points, followed by SmartBots@Ulm (3242 points) and ToBi (3198 points).
In the Clean-up test, our robot Cosero showed that it can recognize
object which were distributed in the arena. It grasped a drink and
medicine from the fridge and delivered it to their respective
locations. While placing the beer on the couch table, it spilled it,
however. Afterwards, it found two more drinkson the dinner table and
attempted to store them when the test timed out.
In the Emergency Situation test, Cosero guided a person to the exit. Our robot served as a butler in the Open Challenge, delivering drinks to waving persons. After Stage 1, NimbRo is leading with 4247 points, followed by SmartBots@Ulm (2792 points) and TOBI (2748 points).
Our team NimbRo participates at the @Home League competiton of RoboCup German Open 2013 in
On the first competition day, our robots Dynamaid and Cosero registered for the competiton by handing over the registration form.This RIPS test was evaluated by the team leaders and the Technical Commitee. Our robotsreceived the top score of 925 points.
A mechanical problem in Cosero's torso prevented to participate in the Follow Me test.
The Cocktail Party test went very well. Cosero took orders, fetched and delivered drinks.
After the three tests, our team is leading (1775 points) followed by SmartBots@Ulm (1561 points) and TOBI (Univ. of Bielefeld, 1471 points).
Our team won the @Home League competition.
In the final, our robot Cosero demonstrated the approaching, bi-manual grasping and moving of a chair to a target pose. It also approached and grasped a watering can with both hands and watered a plant. After this demonstration, our robot Dynamaid fetched a drink and delivered it to the jury. In the meanwhile, Cosero approached a transport box, from which it grasped an object using grasp planning. This demonstration convinced the high-profile jury, which awarded the highest number of points in both categories (league-internal jury: scientific contribution, relevance, presentation and performance; external jury: originality, usability, difficulty and success). Together with the lead after Stage 2, our team received 100 normalized points, followed by eR@sers (Japan, 74 points) and ToBi (Univ. of Bielefeld, 64 points).
In the General Purpose Service Robot test, our robot Cosero had to
recognize complex speech commands. It correctly recognized two
commands, which gave the most points in this test.
In the Demo Challenge, an immobile person used a handheld PC to teleoperate the robot. The person sent the robot to fetch a drink. The robot recognized that the requested drink was not available and the user could select another drink in the transmitted camera image. After the robot delivered the drink, it recognized a pointing gesture and navigated to the referenced object in order to pick it up from the ground.
In the Restaurant test, our robot Cosero way guided through a previously unknown bar. The guide showed the robots where the shelves with drinks and the individual tables where. Our robot built a map of this environment and took an order. Afterwards, it navigated to the food shelf to search for requested snacks.
After Stage 2, NimbRo is leading with 6938 points, followed by WrightEagle (4677 points) and eR@sers (Japan, 3547 points).
In the Clean Up test, our robot Cosero had to find objects that
were distributed in the apartment, recognize them, and bring them to
their place. Our robot detected three objects, from which two were
correctly recognized as unknown objects. It grasped all three objects
and deposited them in the trash bin.
In the Open Challenge, Cosero demonstrated that it could recognize a waving person. It took over an empty cup from this person and threw it into the trash bin. Afterwards, it approached a watering can and watered a plant. After finishing all test of Stage 1, NimbRo is leading (5071 points), followed by WrightEagle (3398 points) and ToBi (2627 points).
Our robot Cosero performed the new Follow-Me test. It learned the
face of a previously unknown person, followed it although its
line-of-sight to the person was blocked temporarily, and went with the
person into a small elevator. At another floor, the robot went out of
the elevator again.
In the Who is Who test, Cosero performed very well. He learned the faces of three persons, took an order, fetched three drinks, and delivered two of them, before the time run out. After the third test, NimbRo is leading with 2399 points, followed by WrightEagle (China, 2098 points) and ToBi (Bielefeld, 1283 points).
Our team participates at RoboCup 2012 in Mexico City. On the second setup-day, the robots had to register for the competition while Jörg presented our team poster to the other team leaders.
Our team won the RoboCup German Open @Home competition.
In the final, our robot Cosero showed the pushing of a chair and the
watering of a plant. For both tasks, it used real-time registration of
3D models with the current RGB-D camera images. Our robot Dynamaid
delivered some snacks to the jury. Jury members could raise their hands
to get a snack. This performance was awarded the highest number of
points by both parts (exec and external) of the jury.
The team b-it-bots (Hochschule Rhein-Sieg,Sankt Augustin) reached the second place in the @Home competition. Team Golem from Mexico came in third.
In the Demo Challenge, our robot Cosero recognized colored and white
laundry shown to it, recognized pointing gestures, and picked up
laundry from the floor. It also put away two kitchen items into
Cosero performed the Enhanced Who Is Who test almost perfectly. It learned names and faces of three persons, understood a drink order, fetched three drinks and delivered two of them to the correct person.
The Shopping Mall test also went very well. Here, Cosero learned the map of an unknown environment by following a guide, took a shopping order and collected two of the three requested objects.
Consequently, after Stages 1 and 2, our team is leading with 8550 points, followed by b-it-bots (4781 points) and SmartBots (4291 points).
In the Who Is Who test, our root Cosero found four persons and
recognized three of them.
In the General Purpose Service Robot test, Cosero understood three complex speech commands and found the requested objects.
The last test today was the Open Challenge. Here, Cosero was guided by a human by taking its hand, carried a table together with the guide, and pushed a chair to the table. After the second day, we were leading the competition with 5300 points, followed by SmartBots (Ulm, 3491 points) and b-it-bots (Sankt Augustin, 3431 points).
Our team participates at the RoboCup German Open 2012 competition in Magdeburg.
On the first day, our robots had to register themselves and to perform the Follow Me and Go Get It tests.
In Follow Me, our robot Cosero learned the face of a previously unknown person and followed him trough a parcour. The robot was not disturbed by another person walking in between the two, recognized its leader again after he disappeared, and recognized a stopping gesture.
In Go Get It, Cosero found the requested object in the kitchen, but could not reach it, because it was outside the workspace of its arms.
After the first day, our team is leading with 2340 points, followed by SmartBots (Ulm, 2004 points) and Golem (Mexico, 1604 points).
At the 15th RoboCup International Symposium, the paper Jörg Stückler and Sven Behnke: "Compliant Task-Space Control with Back-Drivable Servo Actuators" received the Best Paper Award.
We won the @Home competition.
In the final, we used both robots. Cosero carried a table, together with a person who guided the robot by pulling and pushing the table. Cosero also turned on the cooking plate, fetched some egg dough and poured it into a pan to make an omelet. In the meanwhile, Dynamaid got a bottle of orange juice from the fridge. This performance was awarded the highest score from all three parts of the jury. Together with the top score from Stage II, this resulted in an optimal 300 points.
The General Purpose Service Robot test went very well. Our robot Cosero understood complex speech commands, fetched the requested object, and was not confused by a command to fetch an object that was not at the specified location. In the Demo Challenge, Cosero cleaned the apartment. A human could show the robot where white and colored loundry was to be put and the robot collected some clothes. It also cleaned up other objects and put them at their place. This was awarded with the highest number of points of all remaining 12 teams. After Stage II, our team is leading with some distance, followed by WrightEagle from China.
In the General Purpose Service Robot test, Cosero partially understood a complex command and went to the correct place. The Go-Get-It test went well. Cosero found a known object and delivered it. In the Shopping Mall test, Cosero had severe difficulties with speech recognition. Hence, it could not take the order which items should be shopped and received only partial points.
Cosero demonstrated in the Follow-Me test that he can follow a previously unknown person, recognize gestures and distinguish this person from another person. Due to the noisy environment, Cosero had some difficulties to understand names in the Who-is-Who test. Nevertheless, our robot detected and recognized four persons correctly. In the Open Challenge, Cosero prepared a breakfast. It opened a bottle, poured milk in a bowl and fetched a spoon. This performance was rewarded with the highes number of points of all teams.
Our team NimbRo participates at RoboCup 2011, which takes place at the Expo Center in Istanbul.
In the evening, our @Home robots Dynamaid and Cosero registered themselves for the competition in the Robot Inspection and Poster Session test. They reached the highest number of points of all 19 teams in this test.

NimbRo participated for the first time in the @Home league at RoboCup German Open 2009 during Hannover Fair.
In Stage I, we used Robotinho for the introduce task. It explained
itself and Dynamaid and interacted with a human in a natural way. For
the follow me task, we used Dynamaid. She was able to quickly follow an
unknown human though the arena, outside, and back into the arena. She
also could be controlled by voice commands. Dynamaid also did the fetch
and carry task very well. She took spoken orders from the human
user and delivered reliably the requested object.
In Stage II, Dynamaid did the walk and talk task perfectly. A human
showed her places in the apartment that she could visit afterwards as
requested by spoken commands. In the demo challenge, the users could
order different drinks that she fetched quickly and reliably from
different places in the apartment.
In the final, Robotinho gave a tour though the apartment while
Dynamaid fetched a drink for a guest [video].
