Exoskeletons as Mechatronic Design Example

Hannes Bleuler, Mohamed Bouri, Solaiman Shokur, Jeremy Olivier, Jemina Fasola, Romain Pierre François Baud, Tristan Hubert Vouga, Amalric Louis Ortlieb

Exoskeletons are a perfect example of a mechatronics product. They illustrate the close integration and interdependence of mechanical design, drive train, sensors, control strategy and user interface. Recent developments of our lab will be discussed in det ...

Needle for invasive medical use and needle assembly

Simon Nessim Henein, Charles Baur

A needle for invasive medical use includes a long extended cylindrical needle shaft having an axis and an outer surface area, with a short shaft end at a first end of the shaft with a beveled tip with a pointed end, and a needle hub attached to a second en ...

A Miniature Multimodal Actuator for Effective Tactile Feedback: Design and Characterization

Huaiqi Huang

We designed a miniature multimodal actuator by combining servomotors and vibrators. The actuator is mainly designed to non-invasively deliver tactile information to human skin by high-frequency vibration and low-frequency pressures simultaneously. By utili ...

Fluid Flow Analysis of a New Finned Piston Reciprocating Compressor Using Pneumatic Analogy

Alfred Rufer, Mahbod Heidari

The goal of this paper is to investigate the fluid flow analysis in a novel multilayered finned reciprocating compressor, adopting a so-called “pneumatic-Electric” analogy using a lumped methodology. This machine includes two sets of concentric annular fin ...

Phase-Shift Master-Slave Mechanisms for High Angular-Speed Wedge-Prism Systems

Reymond Clavel, Olivier Chappuis

Laser micro-machining requires high dynamic laser spot trajectory and accuracy to control the laser beam scanning. A well-known technique to scan a laser beam over a specimen is to use a pair of wedge-prisms. However, it is difficult to master-slave the ph ...

A dual-axis pointing mirror with moving-magnet actuation

Nico de Rooij, Wilfried Noell, Caglar Ataman, Sébastien Lani

A large-aperture and large-angle MEMS-based 2D pointing mirror is presented. The device is electromagnetically actuated by a moving-magnet/stationary-coil pair and potentially suited for high power laser beam shaping and beam pointing applications, such as ...

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 ...

Exploiting passive dynamics for robot throwing task

Robin Thandiackal

Throwing is a complex and highly dynamic task. Humans usually exploit passive dynamics of their limbs to optimize their movement and muscle activation. In order to approach human throwing, we developed a double pendulum robotic platform. To introduce passi ...

Electromechanically induced absorption in a circuit nano-electromechanical system

Tobias Kippenberg, Albert Schliesser, Xiaoqing Zhou

A detailed analysis of electromechanically induced absorption (EMIA) in a circuit nano-electromechanical hybrid system consisting of a superconducting microwave resonator coupled to a nanomechanical beam is presented. By performing two-tone spectroscopy ex ...

LTCC integrated miniature Rb discharge lamp module for stable optical pumping in miniature atomic clocks and magnetometers

Herbert Shea, Thomas Maeder, Peter Ryser, Vinu Lalgudi Venkatraman, Fabrizio Vecchio

We report here on an integrated mini-lamp module (15x26x4 mm3) with a microfabricated rf-powered Rb dielectric barrier discharge (DBD) lamp (10x10x3 mm3) positioned on top of a 0.6 mm thick (thickness adjustable) 4-layer LTCC (Low Temperature Co-fired Cera ...

Constrained spectrum control using MPC

Colin Neil Jones, Jean-Hubert Hours

Well-known model predictive control (MPC) theory for constrained linear time-invariant (LTI) systems is extended to accommodate hard constraints and cost penalizations on the spectra of the system’s output trajectories. Thus the proposed method facilitates ...

Hydrodynamics of High Specific Power Pumps for Off-Design Operating Conditions

Part load operation of high energy centrifugal pumps is associated with increased vibration levels which may adversely affect the machines operational safety. The main sources of vibrations in centrifugal pumps are of hydrodynamic nature. The interaction b ...
