Civil Aircraft development and production are facing significant challenges in future. On the one hand, the flight-path to carbon neutral aviation, like using liquid hydrogen, will require game changing technologies. Simultaneously, competition, especially on the single aisle market, is evolving fast and puts pressure on market shares and margins. The necessity of an adaptable and highly efficient production becomes more evident than ever. One contribution to achieve this goal is the research project “Intelligent modular robotics and Integrated Production System Design for Aircraft Manufacturing” (iMOD). Namely, it will analyze challenges regarding (1) an integrated and Digital Twin-based system design approach, (2) flexible and modular robotics to support workers with unergonomic tasks and (3) a flexible intralogistics based on Automated Guided Vehicles (AGVs). Those three aspects will be integrated into an approach that uses semantic technologies to connect the different components across different levels of functionality and different life cycle phases.

Peristaltic conveyance can be used for the sorting and transport of delicate and nonrigid objects such as meat or soft fruit. The non-linearity and stochastic behavior of peristaltic systems make them difficult to control. Optimizing controllers using machine learning represents a promising path to effective peristaltic control but currently, there is no suitable simulated model of a peristaltic table in which to run these optimizations. A simple, simulated model of a peristaltic conveyor that can be used for optimizing peristaltic control on a variety of peristaltic tables is presented. This simulator is demonstrated through a limited control problem evaluated on our real-world system that is built for peristaltic conveyance. This simulator is available as the python package PeriSim so that it can be used by the robotics community for peristaltic control development.

The world is becoming more digitised with the rise of modular robotic systems. Therefore, with the increasing demands and needs for robotics, the modular robotic domain was introduced as an essential key part of Internet-of-Things (IoT). modular self-configurable robotic systems (E.g. swarms) are classed as "smart"autonomous machines with kinematic properties, defined by a set of interconnected links, modules and algorithms to achieve the required three-dimensional (3D) or two-dimensional (2D) complex shape or hierarchical structure. Due to its "intelligent'' concept, it beame suitable for its deployment in the Internet of Robotic Things (IoRT) domain. Thus, becoming a key part of it and establishing itself as the newly revolutionised Internet of modular Robotic Things (IoMRT). This paper presents a survey that highlights and discusses this novel IoMRT concept that focuses on self-reconfigurable modular robots and robotic systems by discussing their criteria, characteristics, architecture, and design. The security, safety, and privacy aspects are also presented and discussed, making it among the first papers to focus on this topic and its future. Moreover, the main drawbacks and challenges are also highlighted, while the already available solutions are also presented and analysed. A brief analysis regarding each solution is also presented with an insight into their future work. Additionally, more work was presented regarding the security aspect(s) of modular robotic systems to protect them from possible cyber or/and physical attacks. Thus, covering all possible aspects of the IoMRT.

This study aims at providing a control-learning framework capable of generating optimal locomotion patterns for the modular robots. The key ideas are firstly to provide a generic control structure that can be well-adapted for the different morphologies and secondly to exploit and coevolve both morphology and control aspects. A generic framework combining robot morphology, control and environment and on the top of them optimization and evolutionary algorithms are presented. The details of the components and some of the preliminary results are discussed.

Digital Manipulatives embed computation in familiar children's toys and provide means for children to design behavior. Some systems use "record and play" as a form of programming by demonstration that is intuitive and easy to learn. With others, children write symbolic programs with a GUI and download them into a toy, an approach that is conceptually extensible, but is inconsistent with the physicality of educational manipulatives. The challenge we address is to create a tangible interface that can retain the immediacy and emotional engagement of "record and play" and incorporate a mechanism for real time and direct modulation of behavior during program *** introduce the Backpacks, modular physical components that children can incorporate into robotic creations to modulate frequency, amplitude, phase and orientation of motion recordings. Using Backpacks, children can investigate basic kinematic principles that underly why their specific creations exhibit the specific behaviors they observe. We demonstrate that Backpacks make tangible some of the benefits of symbolic abstraction, and introduce sensors, feedback and behavior modulation to the record and play paradigm. Through our review of user studies with children ages 6-15, we argue that Backpacks extend the conceptual limits of record and play with an interface that is consistent with both the physicality of educational manipulatives and the local-global systems dynamics that are characteristic of complex robots.
