Locomotion studies and modeling of the long-tailed lizard Takydromus sexlineatus
Auke Ijspeert, Konstantinos Karakasiliotis
Morphology is an important factor in locomotion. It may guide the control strategies that an animal or a robot uses for efficient locomotion. In this paper we try to understand the locomotion strategies of a lizard with a distinctive feature, the long-tail ...
Ieee2012Concept of Modular Kinematics to Design Ultra-high Precision Parallel Robots
Miniaturisation will be the key challenge for the next decade in numerous industrial fields, such as microelectronics, optics and biomedical engineering. Although most of their products already achieve footprints of some square millimeters, the trend towar ...
EPFL2012Competition between kinematic and dynamic waves in floods on steep slopes
We present a theoretical stability analysis of the flow after the sudden release of a fixed mass of fluid on an inclined plane formally restricted to relatively long time scales, for which the kinematic regime is valid. Shallow-water equations for steep sl ...
Cambridge University Press2010Design of hybrid-kinematic mechanisms for machine tools
The machine tool industry is a well established, old and extremely important branch of today's manufacturing industry. With the ongoing globalization and the resulting increase of competition in this industry, the manufacturers have to push their technolog ...
EPFL2009Real-Time Joint Coupling of the Spine for Inverse Kinematics
Ronan Boulic, Daniel Raunhardt
In this paper we propose a simple model for the coupling behavior of the human spine for an inverse kinematics framework. Our spine model exhibits anatomically correct motions of the vertebrae of virtual mannequins by coupling standard swing and revolute j ...
University of Applied Sciences Dusseldorf2008Optimisation de la conception du robot parallèle Delta cube de très haute précision
In the high-precision industry, most operations require the use of robots able to accomplish highly accurate and repeatable motions. In order to meet the desired level of absolute accuracy, one has to limit or even suppress the effects of different sources ...
EPFL2006Orion MinAngle: A flexure-based, double-tilting parallel kinematics for ultra-high precision applications requiring high angles of rotation
If you need to design ultra-high precision devices for mechanisms with multiple axes there are not a lot of ways leading around flexure-based joints. Using this type of articulations totally eliminates backlash and friction and is, by this, providing an ac ...
2005Calibration of the 5-dof parallel kinematics HITA-STT
The parallel kinematics machine tool HITA-STT (Stiffness Tracking Technology) developed by Willemin–Machines S.A. and EPFL is now able to machine. This machine can reach accelerations of 5g. It is characterized by a tilt of ± 60° around the B-axis. This ch ...
2004Méthode systématique de conception de cinématiques parallèles
Parallel kinematics structures currently find increasing industrial applications, particularly in packaging and assembly. With very few exceptions, machine-tools with parallel kinematics are limited to mechanisms with three or six degrees of freedom. Moreo ...
EPFL2004Ambulatory system for human motion analysis using a kinematic sensor: Monitoring of daily physical activity in the elderly
Kamiar Aminian, Philippe Robert, Anisoara Ionescu, Bijan Najafi
A new method of physical activity monitoring is presented, which is able to detect body postures (sitting, standing, and lying) and periods of walking in elderly persons using only one kinematic sensor attached to the chest. The wavelet transform, in conju ...
