The Robotics for Development of Cognition Collegium (RobotDoC)
The RobotDoC Collegium is a multi-national doctoral training network for the interdisciplinary training on developmental cognitive robotics. The RobotDoC Fellows develop advanced expertise of domain-specific robotics research skills and of complementary transferrable skills for careers in academia and industry. They acquire hands-on experience through experiments with the open-source humanoid robot iCub, complemented by other existing robots available in the network's laboratories. The RobotDoC project is divided in seven nodes, Body, Brain, Feel and Want, See and Act, You and I, Think and Talk, Grow. The Knowledge Technology Group is in charge of the "BRAIN" node integrating new principles of brain-inspired learning in embodied cognitive robots. Two research lines are being address in this node, "Neural Emotion and Action Integration" and "Neural Cognitive Integration".
Neural Emotion and Action Integration - Nicolas Navarro-Guerrero
Innate defensive mechanisms belong to the most important and essential capabilities for any organism. Although many of those innate responses are hard-coded in the brain, they are not sufficient for organisms' survival. They have to adapt to new and unexpected situations within their lifetime and thereby be able to interact effectively with their environment. A deeper understanding of these innate and learned defensive mechanisms could also be helpful for the development of future robot generations, making them more adaptable and robust.
We suggest a computational architecture to study affective evaluation of stimuli as an artificial affective and self-protective system. In addition, we plan to implement and test the proposed architecture on a real humanoid robot in a home-like environment. We focus on learning capabilities applied to the detection of harmful situations to the robot and seek for energy when required. These kinds of basic abilities are a part of affective and self-protective mechanisms that support more complex behaviors in biological organisms. We aim to emulate some of these capabilities in a humanoid robot. Our computational model is be based on neuro-physiological findings.
Neural Cognitive Integration - Junpei Zhong
When social robots and persons are sharing the same domestic space, it is critical to make the robots act, think, and predict what other partners (humans or robots) do, which relates to building up an artificial system of social cognition with humanoid robots. The examination of the mirror neuron system model is one of the possible approaches to realize social interaction for social robotics. This system is considered to be one of the critical areas for social cognition.
The main objective of this project is to build up a computational functional model of the mirror neuron system, with emphasis on its role in action understanding with consideration of object affordance. To justify the correctness of our model, two NAO robots are applied to accomplish the experiment. Moreover, this research is also beneficial to the research of social robotics, in which it is crucial to make the robots act, think and predict what other partners (humans or robots) do when social robots and persons are sharing the same domestic space.
Impressions from the Lab
Towards the development of an artificial affective and self-protective system, we investigate and develop a real-world reinforcement learning approach to autonomously recharge a humanoid Nao robot. Using a supervised reinforcement learning approach, we are able to teach the robot to navigate towards a docking station, and thus extend the duration of autonomy of the Nao by recharging. The control concept is based on visual information provided by naomarks and six basic actions. It was developed and tested using a real Nao robot within a home environment scenario. No simulation was involved.
