Closed Loop Interactive Embodied Reasoning for Robot Manipulation

no code implementations23 Apr 2024 Michal Nazarczuk, Jan Kristof Behrens, Karla Stepanova, Matej Hoffmann, Krystian Mikolajczyk

Embodied reasoning systems integrate robotic hardware and cognitive processes to perform complex tasks typically in response to a natural language query about a specific physical environment.

Learning body models: from humans to humanoids

no code implementations6 Nov 2022 Matej Hoffmann

These experiments inform our work in which we construct embodied computational models on humanoid robots that address the mechanisms behind learning, adaptation, and operation of multimodal body representations.

Human keypoint detection for close proximity human-robot interaction

no code implementations15 Jul 2022 Jan Docekal, Jakub Rozlivek, Jiri Matas, Matej Hoffmann

In particular, (i) we survey existing datasets with human pose annotation from the perspective of close proximity images and prepare and make publicly available a new Human in Close Proximity (HiCP) dataset; (ii) we quantitatively and qualitatively compare state-of-the-art human whole-body 2D keypoint detection methods (OpenPose, MMPose, AlphaPose, Detectron2) on this dataset; (iii) since accurate detection of hands and fingers is critical in applications with handovers, we evaluate the performance of the MediaPipe hand detector; (iv) we deploy the algorithms on a humanoid robot with an RGB-D camera on its head and evaluate the performance in 3D human keypoint detection.

Keypoint Detection

Body schema or the body as its own best model

no code implementations6 Jun 2022 Matej Hoffmann

No central representations or maps of its body were found in its central nervous system.

Body models in humans, animals, and robots: mechanisms and plasticity

no code implementations19 Oct 2020 Matej Hoffmann

The key foundation is an internal representation of the body that the agent - human, animal, or robot - has developed.

PreCNet: Next-Frame Video Prediction Based on Predictive Coding

1 code implementation30 Apr 2020 Zdenek Straka, Tomas Svoboda, Matej Hoffmann

Predictive coding, currently a highly influential theory in neuroscience, has not been widely adopted in machine learning yet.

Symbol Emergence in Cognitive Developmental Systems: a Survey

no code implementations26 Jan 2018 Tadahiro Taniguchi, Emre Ugur, Matej Hoffmann, Lorenzo Jamone, Takayuki Nagai, Benjamin Rosman, Toshihiko Matsuka, Naoto Iwahashi, Erhan Oztop, Justus Piater, Florentin Wörgötter

However, the symbol grounding problem was originally posed to connect symbolic AI and sensorimotor information and did not consider many interdisciplinary phenomena in human communication and dynamic symbol systems in our society, which semiotics considered.

Robots as Powerful Allies for the Study of Embodied Cognition from the Bottom Up

no code implementations15 Jan 2018 Matej Hoffmann, Rolf Pfeifer

A large body of compelling evidence has been accumulated demonstrating that embodiment - the agent's physical setup, including its shape, materials, sensors and actuators - is constitutive for any form of cognition and as a consequence, models of cognition need to be embodied.

Where is my forearm? Clustering of body parts from simultaneous tactile and linguistic input using sequential mapping

1 code implementation8 Jun 2017 Karla Stepanova, Matej Hoffmann, Zdenek Straka, Frederico B. Klein, Angelo Cangelosi, Michal Vavrecka

In species that use language, this process is further structured by this interaction, where a mapping between the sensorimotor concepts and linguistic elements needs to be established.

The encoding of proprioceptive inputs in the brain: knowns and unknowns from a robotic perspective

no code implementations20 Jul 2016 Matej Hoffmann, Nada Bednarova

However, coming from robotics and seeking a biologically motivated model that could be used in a humanoid robot, we faced a number of difficulties.

Trade-Offs in Exploiting Body Morphology for Control: from Simple Bodies and Model-Based Control to Complex Bodies with Model-Free Distributed Control Schemes

no code implementations9 Nov 2014 Matej Hoffmann, Vincent C. Müller

Tailoring the design of robot bodies for control purposes is implicitly performed by engineers, however, a methodology or set of tools is largely absent and optimization of morphology (shape, material properties of robot bodies, etc.)
