EMG-Based Analysis of the Upper Limb Motion

Aude Billard, Silvestro Micera, Sahar El Khoury, Iason Batzianoulis

In a human robot interaction scenario, predicting the human motion intention is essential for avoiding inconvenient delays and for a smooth reactivity of the robotic system. In particular, when dealing with hand prosthetic devices, an early estimation of t ...

Collision avoidance in next-generation fiber positioner robotic systems for large survey spectrographs

Denis Gillet, Hannes Bleuler, Jean-Paul Richard Kneib, Mohamed Bouri, Laleh Makarem, Laurent Frédéric Jenni

Some of the next generation massive spectroscopic survey projects, plan to use thousands of fiber positioner robots packed at a focal plane to quickly move in parallel the fiber-ends from the previous to the next target points. The most direct trajectories ...

Learning of Closed-Loop Motion Control

Jonas Buchli, Farbod Farshidian

Learning motion control as a unified process of designing the reference trajectory and the controller is one of the most challenging problems in robotics. The complexity of the problem prevents most of the existing optimization algorithms from giving satis ...

Catching Objects in Flight

Aude Billard, Ashwini Shukla, Seungsu Kim

We address the difficult problem of catching in-flight objects with uneven shapes. This requires the solution of three complex problems: accurate prediction of the trajectory of fastmoving objects, predicting the feasible catching configuration, and planni ...

Learning Cost Function and Trajectory for Robotic Writing Motion

Aude Billard, Hang Yin, Ana Paiva

We present algorithms for inferring the cost function and reference trajectory from human demonstrations of hand-writing tasks. These two key elements are then used, through optimal control, to generate an impedance-based controller for a robotic hand . Th ...

Electron Spin Resonance of Nitrogen-Vacancy Defects Embedded in Single Nanodiamonds in an ABEL Trap

Aleksandra Radenovic, Metin Kayci, Huan-Cheng Chang

Room temperature optically detected magnetic resonance of a single quantum object with nanoscale position control is an outstanding challenge in many areas, particularly in the life sciences. We introduce a novel approach to control the nitrogen-vacancy (N ...

Effect of Loading Rate on Fracture Behaviour of Rock Materials

Yang Zou, Qianbing Zhang

In this paper, experiments are carried out to study the quasi-static and dynamic fracture behaviour of sedimentary, igneous and metamorphic rocks. The notched semi-circular bending method has been employed to determine fracture parameters over a wide range ...

Real-Time Estimate of Velocity and Acceleration of Quasi-Periodic Signals Using Adaptive Oscillators

Auke Ijspeert, Renaud Ronsse

Estimation of the temporal derivatives of a noisy position signal is a ubiquitous problem in industrial and robotics engineering. Here, we propose a new approach to get velocity and acceleration estimates of cyclical/periodic signals near to steady-state r ...

Designing and Fabricating Mechanical Automata from Mocap Sequences

Mark Pauly, Duygu Ceylan

Mechanical figures that mimic human motions continue to entertain us and capture our imagination. Creating such automata requires expertise in motion planning, knowledge of mechanism design, and familiarity with fabrication constraints. Thus, automaton des ...

Indirect, Non-adaptive Control of a Class of Nonlinear Uncertain Systems with Applications to Motion Control of Swimming Robots

Auke Ijspeert, Yannick Morel

Motion control of bio-inspired mobile robotic platforms can prove a challenging problem. In particular, models for the considered type of systems may prove nonlinear, uncertain, and fairly complicated. To address these issues, use of an output predictor-ba ...
