In this paper we present the approaches that we used for this year's RoboCup@Home participation in the Open Platform League. A special focus was put on team collaboration by handing over objects between two robots of different teams that were not connected by network. The robots communicated using natural language (speech synthesis, speech recognition), a typical human-robot “interface” that was adapted to robot-robot interaction. Furthermore, we integrated new approaches for online tracking and learning of an operator, have shown a novel approach for teaching a robot new commands by describing them using natural language and a set of previously known commands. Parameters of these commands are still interchangeable. Finally, we integrated deep neural networks for person detection and recognition, human pose estimation, gender classification and object recognition.

This paper describes the robot Lisa used by team homer- @UniKoblenz of the University of Koblenz-Landau, Germany, for the participation at the RoboCup@Home 2017 in Nagoya, Japan. A spe- cial focus is put on novel system components and the open source con- tributions of our team. We have released packages for object recogni- tion, a robot face including speech synthesis, mapping and navigation, speech recognition interface via android and a GUI. The packages are available (and new packages will be released) on agas-ros-pkg.

RoboCup@Home: Summarizing achievements in over eleven years of competition. Mauricio Matamoros, Viktor Seib, Raphael Memmesheimer, and Dietrich Paulus. In 2018 IEEE International Conference on Autonomous Robot Systems and Competitions (ICARSC), pages 186--191, New York, 2018. IEEE. [ bib | DOI ]

Scientific competitions are important in robotics because they foster knowledge exchange and allow teams to test their research in unstandardized scenarios and compare result. In the field of service robotics its role becomes crucial. Competitions like RoboCup@Home bring robots to people, a fundamental step to integrate them into society. In this paper we summarize and discuss the differences between the achievements claimed by teams in their team description papers, and the results observed during the competition1 from a qualitative perspective. We conclude with a set of important challenges to be conquered first in order to take robots to people's homes. We believe that competitions are also an excellent opportunity to collect data of direct and unbiased interactions for further research.

This paper describes the robot hardware and soft- ware used by team homer@UniKoblenz of the University of Koblenz and Landau, Germany, for the participation in the European Robotics League 2017 for Service Robots in Lisbon. A special focus is put on detailed hardware and software description and novel scientific achievements. For navigation and mapping we use well-established SLAM techniques based on particle filter and grid maps. Object recognition is achieved by clustering of local invariant features. Three-dimensional scans of the environment are acquired using a RGB-D sensor mounted on a pan-tilt unit. In order to manipulate objects a 6 DOF industrial-grade robotic arm is employed. An abstraction layer in our software architec- ture allows for task planning and general purpose task execution. For the improvement of human-robot interaction we developed a generic face model that is synchronized to speech and can show seven different face expressions. This robot face is available as a ROS-node for other teams. Some of the novelties of this year is a new robotic platform and a complete change to ROS that now replaces our previously used software architecture. Further, our object recognition, mapping and navigation algorithms were published as ROS package. Furthermore, improvements were made in speech recognition, object recognition, manipulation as well as 3D mapping.
