Data driven modeling and optimal manipulator control

von: Adriano del Río Fernandez  (École Centrale de Nantes)
In the field of optimal control linear systems are generally desirable. In the case of model predictive control the benefit of a linear system representation is significant, as it implies convexity of the optimization problem and global optimality for every solution. In this context very interesting…

Enhancing Robustness and Adaptability in Robotic Systems: A Quality-Diversity Approach to Addressing Wrong Initial Simulation Parameters and Optimizing Model Parameters

von: Joaquin Arias  (Constructor University)
In a dynamic environment, the capacity of a robot to adapt is crucial. Quality-Diversity (QD) algorithms, which produce multiple effective solutions, are effective at increasing adaptability through a descriptor function. For example, if a robot loses an extremity, thanks to the repertoire of soluti…

Examining the Potential of VVAD-LRS3: A Comprehensive Cross-Comparison throughout State-of-the-Art VVAD Data Sets

von: Karim Zanaty  (Rushford Business School)
Reliable recognition of people's gestures and mimics is crucial to a natural and intuitive interaction between robots (machines) and humans. Voice Activity Detection (VAD) may play a major role in this context. VAD algorithms detect if the person of interest is currently speaking or not. This can be…

Visual Voice Activity Detection with state-of-the-art video classifiers

von: Cedric Kränzle  (Universität Bremen)
Voice Activity Detection (VAD) is a key component in Human Robot Interactions, as it can be used to initiate interactions.There are audio and video based VAD systems, however both have their shortcomings. A recently presented dataset named VVAD-LRS3 enables the training of larger Deep Neural Ne…

Exploration via Constructive Disagreement: Diversity in Ensemble-based Behavior Learning using Niching Migratory Multi-Swarm Optimization

von: Antonia Holsten  (Universität Bremen)
Guiding exploration of the environment via disagreement is a common approach in model-based ensemble learning methods. For the effectiveness of the approach, the ensemble diversity is a crucial property. In this work, we investigate the usage of a state-of-the-art multi-modal optimizer to generate a…

Prototyping, development, and analysis of different contact detection methods for bipeds and quadrupeds

von: Mani Krishna Tippireddy  (Hochschule Stralsund)
Bipedal and quadruped robots are advancing rapidly, showcasing remarkable abilities in traversing complex terrains and executing diverse tasks. Central to their performance is the accurate detection of foot-toground contact, crucial for maintaining stability and balance. Particularly in challenging …

Local Dynamics Adaption for Trajectory Optimization and Stabilization of underactuated AUV's

von: Lukas Rust  (Universität Bremen)
In the recent decades, many missions have been undertaken to investigate Europa, one of Jupiter’s moons. It’s surface consists of a thick ice crust which covers a deep ocean underneath it. To inspect the ocean a system was conceptualized at DFKI Bremen which would drill through the ice and then depl…

Episodic Lang-Term Memory for Planetary Robotics Autonomous Navigation

von: Andre Felmet  (Universität Bremen)
Long-term autonomous robotic missions, especially in isolated environments, have to cope with various challenges, e.g., limited possibilities for maintenance or recovery in case of failure. Better adaptation of the robot to its environment is therefore the first step towards a more robust behavioura…
