Multisensory feedback makes swimming circuits robust against spinal transection and enables terrestrial crawling in elongate fish

Vertebrate locomotion is due to the interplay of neural oscillators and sensory feedback loops in the spinal cord that interact with the body and the environment. Here, we study these circuits with a focus on undulatory locomotion as produced by elongated ...

Investigating the effect of morphology on the terrestrial gaits of amphibious fish using a reconfigurable robot

Auke Ijspeert, Laura Isabel Paez Coy

The relationship between morphology and locomotion performance in amphibious fish remains poorly understood, particularly in axial-appendage-based and appendage-based movements. To address this, we introduce Polymander, a reconfigurable robot capable of mi ...

Symmetry breaking and gait transition induced by hydrodynamic sensory feedback in an anguilliform swimming robot

Auke Ijspeert, Laura Isabel Paez Coy

The goal of this article is to identify and understand the fundamental role of spatial symmetries in the emergence of undulatory swimming using an anguilliform robot. Here, the local torque at the joints of the robot is controlled by a chain of oscillators ...

Identification of the trade-off between speed and efficiency in undulatory swimming using a bio-inspired robot

Auke Ijspeert, Karen Ann J Mulleners, Laura Isabel Paez Coy, Kamilo Andres Melo Becerra, Alexandros Anastasiadis, Eric Daniel Tytell

Anguilliform swimmers, like eels or lampreys, are highly efficient swimmers. Key to understanding their performances is the relationship between the body’s kinematics and resulting swimming speed and efficiency. But, we cannot prescribe kinematics to livin ...

Beyond undulation! Body morphology and sensing components of elongated animals and robots reveal skills to maintain competent locomotion

Laura Isabel Paez Coy

Locomotion is an essential evolutive innovation of living beings that allows them to colonize and dominate the planet. As diverse as animal morphologies are (living) and were (extinct), their locomotion modalities are also diverse. In particular, animal mo ...

Emergence of robust self-organized undulatory swimming based on local hydrodynamic force sensing

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

Undulatory swimming represents an ideal behavior to investigate locomotion control and the role of the underlying central and peripheral components in the spinal cord. Many vertebrate swimmers have central pattern generators and local pressure-sensitive re ...
