Workshop on Shared Autonomy at IROS

We held a successful workshop at IROS on the topic of Shared Autonomy. It brought together different perspectives and approaches on how to deal with (multiple) autonomous agents and how to organize their behavior.

reaCog 2 — Action Selection

As a further step, details and simulation about the action selection network have been presented at AISB 2017:

reaCog – a minimal cognitive system

Finally, the paper on our minimal cognitive system appeared: it describes the underlying embodied and biologically inspired system for a walking robot. And it introduces the cognitive expansion part: at first, how the internal model can be recruited for internal simulation. And second, how the overall processing structure is organized.

Shared Autonomy

Recently, my focus turned more and more towards interaction. This leads to the question how different autonomous systems can, first of all, coexist in a shared space and deal with shared resources. In the long run, the goal is of course to extend this towards joint and collaborative behavior. But while this requires implicit and explicit coordination, it also requires that agents align their autonomous behavior and respect constraints given through other agents.

How children interact with Nao

We presented our work on a framework for the humanoid robot Nao at ICDL Epirob 2016 in Paris. The framework allows to setup game like interactions with the robot and was used for a small series of experiments. During these experiments, pre-schoolers interacted with Nao in a learning task that was designed as a small game.

Mental Simulation in Insects and Systems

A perspective on the importance of mental simulation for minimal system approaches has appeared in PNAS:

Perspective on Representations

We published a joint article on how representations are enriched during development. The article offers a detailed review on developmental work with children and how their representations develop, especially before language.

Mental States as Emergent Properties

Together with our chapter on cognitive properties of the minimal cognitive system, a commentary appeared on the emergent properties of such systems. It is part of the Open Mind (online) publication series:

A Population-Code based Body Model

We applied the MMC approach to a population-code based representation – this allows to decompose complex robotic structures into simple, local geometric relations that can be easily solved in parallel. The population-code representation shall be utilized in the future to allow for integration of additional sensory signals. The paper has been presented at the IJCNN in Ireland, 2015:

Population based encodings allow to represent probabilistic and fuzzy state estimates. Such a representation will be introduced and applied for the case of a redundant manipulator. Following the Mean of Multiple Computations principle, a neural network model (PbMMC) is presented in which the overall complexity is divided into multiple local relationships. This allows to solve inverse, forward and mixed kinematic problems. The local transformations in between the kinematic variables can be sufficiently well learned by small single MLP layers. … the model as such is quite flexible as it can keep track of multiple possible solutions at the same time.
