Neural Network-based Robotic Grasping via Curiosity-driven Reinforcement Learning (NeuralGrasp)

Reinforcement Learning (RL) helps robots learn behaviors including complex manipulation and navigation tasks autonomously, purely from trial-and-error interactions with the environment and resulting in an optimal policy, which represents the desired behavior of the robot. However, exploring the environment to collect useful experience data is often difficult, especially for grasping tasks where high-dimensional visual data and multiple degrees of freedom are involved. The project proposes to address this problem in RL by looking into exploration strategies inspired by infant cognition and sensorimotor development, particularly the use of curiosity as an intrinsic motivation.

Bio-inspired Indoor Robot Navigation (BIONAV)

Bio-inspired robot navigation is inspired by neuroscience and navigation behaviors in animals and makes hypotheses about how navigation skills are acquired and implemented in an animal's brain and body. This project aims at testing some of these hypotheses, and to develop the underlying mechanisms towards a biologically plausible navigation system for a real robot platform, including spatial representation, path planning and collision avoidance.

Project A5 - Crossmodal learning in a neurobotic cortical and midbrain model

The goals of project A5 are (1) to develop novel neurocomputational techniques to improve our understanding of the superior colliculus (SC) and linked cortical areas; (2) to design and implement a self-organizing audiovisual model of these cortico-collicular networks in a physical robot; and (3) to compare both the model’s neural activity and the robot’s physical behaviour to the neural activity and physical behaviour of humans. The project will produce a novel computational architecture that can direct a robot’s gaze in a natural way to relevant stimuli.

Project C4 - Vision- and action-embodied language learning

Project C4 focuses on language learning by an embodied agent—one that experiences its world through action and multisensory perception—to understand how spatio-temporal information is processed for language. The goal is to build an embodied neural- and knowledge-based model that processes audio, visual, and proprioceptive information and learns language grounded in these crossmodal perceptions. As a learning architecture, an MTRNN will be used, which is a deep recurrent neural network designed both to model temporal dependencies at multiple timescales and to reflect the recurrent connectivity of the cortex in a conceptually less complex structure.

SOCRATES - Social Cognitive Robotics in The European Society

To address the aim of successful multidisciplinary and intersectoral training, SOCRATES training is structured along two dimensions: thematic areas and disciplinary areas. The thematic perspective encapsulates functional challenges that apply to R&D. The following five thematic areas are identified as particularly important, and hence are given special attention in the project: Emotion, Intention, Adaptivity, Design, and Acceptance. The disciplinary perspective encapsulates the necessity of inter/multi- disciplinary and intersectoral solutions. Figure 1 illustrates how the six disciplinary areas are required to address research tasks in the five thematic areas. For instance, to successfully address an interface design task in WP5, theory and practice from all disciplinary areas typically must be utilised and combined. SOCRATES organises research in five work packages WP2-6, corresponding to the thematic areas Emotion, Intention, Adaptivity, Design, and Acceptance.

Project Managers: Dr. Sven Magg, Dr. Cornelius Weber
Associates: To be recruited.

European Training Network: Safety Enables Cooperation in Uncertain Robotic Environments (SECURE)

The majority of existing robots in industry are pre-programmed robots working in safety zones, with visual or auditory warning signals and little concept of intelligent safety awareness necessary for dynamic and unpredictable human or domestic environments. In the future, novel cognitive robotic companions will be developed, ranging from service robots to humanoid robots, which should be able to learn from users and adapt to open dynamic contexts. The development of such robot companions will lead to new challenges for human-robot cooperation and safety, going well beyond the current state of the art. Therefore, the SECURE project aims to train a new generation of researchers on safe cognitive robot concepts for human work and living spaces on the most advanced humanoid robot platforms available in Europe. The fellows will be trained through an innovative concept of project- based learning and constructivist learning in supervised peer networks where they will gain experience from an intersectoral programme involving universities, research institutes, large and SME companies from public and private sectors. The training domain will integrate multidisciplinary concepts from the fields of cognitive human-robot interaction, computer science and intelligent robotics where a new approach of integrating principles of embodiment, situation and interaction will be pursued to address future challenges for safe human-robot environments.
This project is funded by the European Union’s Horizon 2020 research and innovation programme

Cooperating Robots (CoRob)

Object detection an labeling help robots understand the environment in which they will perform exploration and navigation tasks. The success of tasks such as cleaning an environment depends on the correct recognition of objects or places that should be cleaned. The use of depth sensors can help robots to create representations of these objects. The challenging aspect is to make a robot understand that the same object will look different each time, with different perceived sizes, shapes, colours, etc. The objective of the CoRob Project is to develop approaches that allow a team of robots to learn and generalize the knowledge about the objects acquired from its sensors. As the knowledge will be distributed in the team efficient ways to transfer this knowledge between robots should also be implemented.

Gestures and Reference Instructions for Deep robot learning (GRID)

The communication task is one of the most important tasks within the area of Human-Robot Interaction (HRI). Spoken language alone sometimes can lead to misunderstanding information or is not enough to express reference instructions, for example. This project proposes to solve this problem using deep neural architectures, simulating multi-modal processing in the human brain.

What it Means to Communicate (NESTCOM)

What does it mean to communicate? Many projects have explored verbal and visual communication in humans as well as motor actions. They have explored a wide range of topics, including learning by imitation, the neural origins of languages, and the connections between verbal and non-verbal communication. The EU project NESTCOM is setting out to analyse these results to contribute to the understanding of the characteristics of human communication, focusing specifically on their relationship to computational neural networks and the role of mirror neurons in multimodal communications.

Midbrain Computational and Robotic Auditory Model for focused hearing (MiCRAM)

This research is a collaborative interdisciplinary EPSRC project to be performed between the University of Newcastle, the University of Hamburg and the University of Sunderland. The overall aim is to study sound processing in the mammalian brain and to build a biomimetic robot to validate and test the neuroscience models for focused hearing.

We collaboratively develop a biologically plausible computational model of auditory processing at the level of the inferior colliculus (IC). This approach will potentially clarify the roles of the multiple spectral and temporal representations that are present at the level of the IC and investigate how representations of sounds interact withauditory processing at that level to focus attention and select sound sources for robot models of focused hearing.
