Performance analysis of jump-gliding locomotion for miniature robotics

Dario Floreano, Mirko Kovac, Jean-Christophe Zufferey

Recent work suggests that jumping locomotion in combination with a gliding phase can be used as an effective mobility principle in robotics. Compared to pure jumping without a gliding phase, the potential benefits of hybrid jump-gliding locomotion includes ...

Run-to-Run Disturbance Rejection for Feedforward Path Following of an Adaptively Controlled Unmanned Helicopter

Timm Faulwasser

We present a scheme for run-to-run disturbance rejection in optimization-based feedforward path following of a remotely piloted aircraft system (RPAS). The proposed scheme is based on the inter-run estimation of unknown disturbances, such as wind forces an ...

Real-Time Optimization via Directional Modifier Adaptation, with Application to Kite Control

Sean Costello

The steady advance of computational methods makes model-based optimization an increasingly attractive method for process improvement. Unfortunately, the available models are often inaccurate. The traditional remedy is to update the model parameters, but th ...

Aeroeleasic Investigation of an Annular Transonic Compressor Cascade: Experimental Results

Peter Ott, Virginie Anne Chenaux, Achim Zanker

A reliable determination of the unsteady aerodynamic loads acting on the blades is essential to predict the aeroelastic stability of vibrating compressor cascades with accuracy. At transonic flow conditions, the vibration of the shock may change the blade ...

Optimization of an Airborne Wind Energy System using Constrained Gaussian Processes with Transient Measurements

Colin Neil Jones, Ioannis Lymperopoulos, Sanket Sanjay Diwale

Airborne wind energy systems are built to exploit the stronger and more consistent wind available at high altitudes that conventional wind turbines cannot reach. This however requires a reliable controller design that can keep the airborne system flying fo ...

Optimization of an Airborne Wind Energy System Using Constrained Gaussian Processes

Colin Neil Jones, Ioannis Lymperopoulos, Sanket Sanjay Diwale

Wind resources tend to be significantly stronger and more consistent with increasing altitude. This effect creates a potential for power generation that can be reaped by an Airborne Wind Energy system positioned at elevations exceeding the height of conven ...

Experimental Investigation of the Aeroelastic Stability of an Annular Compressor Cascade at Reverse Flow Conditions

Virginie Anne Chenaux

Compressor surge events are unsafe operating regimes yielding highly unsteady flow fields in which complex aeroelastic phenomena occur. If the blade flutter and forced response behaviour (i.e. aeroelastic stability) can be predicted reliably for normal flo ...

A 10-gram Vision-based Flying Robot

Dario Floreano, Jean-Christophe Zufferey, Jean-Daniel Nicoud, Antoine Beyeler, Adam Klaptocz

We aim at developing ultralight autonomous microflyers capable of freely flying within houses or small built environments while avoiding collisions. Our latest prototype is a fixed-wing aircraft weighing a mere 10 g, flying around 1.5 m/s and carrying the ...
