Role of Compliance on the Locomotion of a Reconfigurable Modular Snake Robot

Auke Ijspeert, Stéphane Bonardi, Massimo Vespignani, Kamilo Andres Melo Becerra

This paper presents the results of a study on the effect of in-series compliance on the locomotion of a simulated 8-DoF Lola-OP Modular Snake Robot with added compliant elements. We explore whether there is an optimal stiffness for gait, terrain type, or s ...

Challenges in the Locomotion of Self-Reconfigurable Modular Robots

Massimo Vespignani

Self-Reconfigurable Modular Robots (SRMRs) are assemblies of autonomous robotic units, referred to as modules, joined together using active connection mechanisms. By changing the connectivity of these modules, SRMRs are able to deliberately change their ow ...

Compliant snake robot locomotion on horizontal pipes

Auke Ijspeert, Massimo Vespignani, Kamilo Andres Melo Becerra, Mehmet Hasan Mutlu

In this paper we introduce a body-compliant Modular Snake Robot executing rolling gaits on different cylindrical geometries. In the state of the art it is considered that an active shape adaptation to the terrain while a gait is executed produces better pe ...

Rich periodic motor skills on humanoid robots: Riding the pedal racer

Auke Ijspeert, Jesse van den Kieboom, Massimo Vespignani, Luc Guyot

Just as their discrete counterparts, periodic or rhythmic dynamic motion primitives allow easily modulated and robust motion generation, but for periodic tasks. In this paper we present an approach for modulating periodic dynamic movement primitives based ...

Automatic Generation of Reduced CPG Control Networks for Locomotion of Arbitrary Modular Robot Structures

Auke Ijspeert, Rico Möckel, Alexander Spröwitz, Soha Pouya, Jesse van den Kieboom, Stéphane Bonardi, Massimo Vespignani

The design of efficient locomotion controllers for arbitrary structures of reconfigurable modular robots is challenging because the morphology of the structure can change dynamically during the completion of a task. In this paper, we propose a new method t ...

Horse-like walking, trotting, and galloping derived from kinematic Motion Primitives (kMPs) and their application to walk/trot transitions in a compliant quadruped robot

Auke Ijspeert, Alexander Spröwitz, Alexandre Tuleu, Massimo Vespignani

This manuscript proposes a method to directly transfer the features of horse walking, trotting, and galloping to a quadruped robot, with the aim of creating a much more natural (horse-like) locomotion profile. A principal component analysis on horse joint ...
