Looking foward to ROSCon 2018 we're highlighting presentations from last year.

Michael presents on how to bring ROS into safety critical systems.

Video

Abstract

This presentation gives an overview about our "Kontrol" development environment for safety critical controllers using ROS and Gazebo. We first analyze existing standards for safety critical controllers for different applications and present the results of an extensive industry survey which concludes that 70-80% of the development costs are spent during the serial development phase. To overcome this burden, we present our approach of a model-based development environment which significantly reduces this cost. We show how ROS and Gazebo can be integrated into one development tool. Finally, we demonstrate the automatic code generation for ROS and ROS2 nodes using Scilab.

Ingo presented how determinism can effect a robotic system. The talk provides an overview of causes of non-determinism. Followed by specific examples of diagnosing determinism in a robotic system and the benefits of eliminating the sources of non-determinism.

Abstract

ROS's foundational style, the asynchronous, loosely coupled compute graph, is great for re-use and distribution, but there's a catch: Nothing guarantees execution ordering. This means, the order in which callbacks and timers are executed can change even when inputs are the same. In many important cases, this leads to different results, and - subtly or not so subtly - changes the robot's behavior. As an example, in the common movebase node, we found reaction times changing between 50 and 200ms, while pure computation time was only 20ms. I will show why this happens, and how to address it, both in the movebase and in general.

Martin and Sergio present an overview of TRADR as well as ROS packages and tools they've developed in the course of the project. Most of the tools have been released as open source packages. And at the end they present some real world use cases where their robots were helpful.

Abstract

Search and Rescue Robotics is an extremely challenging and broad area of robotics that has recently been experiencing enormous progress. In the last 3 years, the EU project TRADR investigated many aspects of the aforementioned field. With this talk, we would like to share with the ROS community the experience acquired in the development of our system based on advanced use of ROS, in testing and using various hardware, and in dealing with end-users that compose the human-robot teams during search and rescue missions.

Darby presents the OpenManipulator and easy way to get into manipulation.

Video

Abstract

This announcement will talk about an OpenManipulator, one of TurtleBot3 Friends. The previous TurtleBot series was able to perform the manipulation function through 'TurtleBot Arm'. In TurtleBot3, the function will be 'OpenManipulator'. ROS-enabled OpenManipulator is a full open robot platform consisting of OpenSoftware, OpenHardware and OpenCR(Embedded board). It is expected that ROS users will be able to upgrade TurtleBot3 with ease. Our goal is to support most of the functionality we need as a service, academic, research and educational robot platform through TurtleBot 3 and OpenManipulator.

Marco introduces the easy_hadeye package using motivation from his groups research using multiple systems.

Video

Abstract

Hand-Eye calibration is a "necessary evil" for enabling the interaction between a robot and its environment, including humans. Determining the precise geometric transformation between the coordinate systems of the robot and the utilized camera(s) is as annoying as it is important in order to avoid errors of multiple centimeters already at a meter distance. easy handeye is a new ROS package that aims at facilitating the computation and management of Hand-Eye calibration, while keeping the library completely generic with respect to hardware and encouraging the user to employ best practices known to date.
