Multi-species atlas resolves an axolotl limb development and regeneration paradox

Can Aztekin, Jixing Zhong, Georgios Tsissios, Evangelia Skoufa

Humans and other tetrapods are considered to require apical-ectodermal-ridge (AER) cells for limb development, and AER-like cells are suggested to be re-formed to initiate limb regeneration. Paradoxically, the presence of AER in the axolotl, a primary mode ...

To regenerate or not to regenerate: Vertebrate model organisms of regeneration-competency and -incompetency

Can Aztekin

Why only certain species can regenerate their appendages (e.g. tails and limbs) remains one of the biggest mysteries of nature. Unlike anuran tadpoles and salamanders, humans and other mammals cannot regenerate their limbs, but can only regrow lost digit t ...

In vivo and ex vivo range of motion in the fire salamander Salamandra salamandra

Enrico Alexander Eberhard

Joint range of motion (RoM) analyses are fundamental to our understanding of how an animal moves throughout its ecosystem. Recent technological advances allow for more detailed quantification of this RoM (e.g. including interaction of degrees of freedom) b ...

Adaptive Compliant Foot Design for Salamander Robots

Auke Ijspeert, Kamilo Andres Melo Becerra, Laura Isabel Paez Coy, Robin Thandiackal

Aquatic stepping gaits in animals arguably display higher speed performance as well as energetic efficiency compared to other gaits using the limbs (i.e walking). This suggest that the foot structure and function contributes at a great extent on the propul ...

Inverse kinematics and reflex based controller for body-limb coordination of a salamander-like robot walking on uneven terrain

Auke Ijspeert, Kamilo Andres Melo Becerra, Konstantinos Karakasiliotis, Robin Thandiackal, Tomislav Horvat

Search and rescue (SAR) missions are being carried out by several types of robots. They include ground, marine and air vehicles depending on the terrain and mission to be tackled. A particular niche for SAR activities are shallow waters. They present high ...

Metapopulation persistence and species spread in river networks

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari

River networks define ecological corridors characterised by unidirectional streamflow, which may impose downstream drift to aquatic organisms or affect their movement. Animals and plants manage to persist in riverine ecosystems, though, which in fact harbo ...

Decoding the mechanisms of gait generation in salamanders by combining neurobiology, modeling and robotics

Auke Ijspeert, Andrej Bicanski, Jérémie Knüsel

Vertebrate animals exhibit impressive locomotor skills. These locomotor skills are due to the complex interactions between the environment, the musculo-skeletal system and the central nervous system, in particular the spinal locomotor circuits. We are inte ...

From lamprey to salamander: an exploratory modeling study on the architecture of the spinal locomotor networks in the salamander

Auke Ijspeert, Andrej Bicanski

The evolutionary transition from water to land required new locomotor modes and corresponding adjustments of the spinal "central pattern generators" for locomotion. Salamanders resemble the first terrestrial tetrapods and represent a key animal for the stu ...

Legged locomotion with spinal undulations

Konstantinos Karakasiliotis

Legged locomotion with spinal undulations is a topic that has not received much attention yet in robotics, though, vertebrates depend on both their limbs and spine to move efficiently in their environments. In this thesis, my aim is to get more insights in ...

Salamandra Robotica II: An Amphibious Robot to Study Salamander-Like Swimming and Walking Gaits

Auke Ijspeert, Alessandro Crespi, André Guignard, Konstantinos Karakasiliotis

In this paper, we present Salamandra robotica II: an amphibious salamander robot that is able to walk and swim. The robot has four legs and an actuated spine that allow it to perform anguilliform swimming in water and walking on the ground. The paper first ...

A Salamander’s Flexible Spinal Network for Locomotion, Modeled at Two Levels of Abstraction

Auke Ijspeert, Andrej Bicanski, Jérémie Knüsel

Animals have to coordinate a large number of muscles in different ways to efficiently move at various speeds and in different and complex environments. This coordination is in large part based on central pattern generators (CPGs). These neural networks are ...

Where are we in understanding salamander locomotion: biological and robotic perspectives on kinematics

Auke Ijspeert, Konstantinos Karakasiliotis

Salamanders have captured the interest of biologists and roboticists for decades because of their ability to locomote in different environments and their resemblance to early representatives of tetrapods. In this article, we review biological and robotic s ...

Organisation of the spinal central pattern generators for locomotion in the salamander: biology and modelling

Auke Ijspeert

Among living tetrapods, salamanders are regarded as most closely resembling the first terrestrial vertebrates, and are therefore an interesting group in which the evolutionary changes in the locomotor behaviour from aquatic to terrestrial habitats can be i ...
