The EPFL jumpglider: A hybrid jumping and gliding robot with rigid or folding wings

Dario Floreano, Jean-Christophe Zufferey, Mirko Kovac

Recent work suggests that wings can be used to prolong the jumps of miniature jumping robots. However, no functional miniature jumping robot has been presented so far that can successfully apply this hybrid locomotion principle. In this publication, we pre ...

A 10-gram Microflyer for Vision-based Indoor Navigation

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

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

2.5D Infrared Range and Bearing System for Collective Robotics

Dario Floreano, Jean-Christophe Zufferey, Timothy Stirling, James Roberts

In the growing field of collective robotics, spatial co-ordination between robots is often critical and usually achieved via local relative positioning sensors. We believe that range and bearing sensing, based on infrared technology, has the potential to f ...

Beat-based synchronization and steering for groups of fixed-wing flying robots

Dario Floreano, Jean-Christophe Zufferey, Sabine Hauert, Severin Leven

Groups of fixed-wing robots can benefit from moving in synchrony to share sensing and communication capabilities, avoid collisions or produce visually pleasing choreographies. For this reason, we provide a strategy to produce global group movement that can ...

An Active Uprighting Mechanism for Flying Robots

Dario Floreano, Jean-Christophe Zufferey, Adrien Briod, Adam Klaptocz, Ludovic Daler

Flying robots have unique advantages in the exploration of cluttered environments such as caves or collapsed buildings. Current systems however have difficulty in dealing with the large amount of obstacles inherent to such environments. Collisions with obs ...

A Miniature Jumping Robot with Self-Recovery Capabilities

Dario Floreano, Jean-Christophe Zufferey, Mirko Kovac

In nature, many animals are able to jump, upright themselves after landing and jump again. This allows them to move in unstructured and rough terrain. As a further development of our previously presented 7g jumping robot, we consider various mechanisms ena ...

Automatically calibrating the viewing direction of optic-flow sensors

Dario Floreano, Jean-Christophe Zufferey, Adrien Briod

Because of their low weight, cost and energy consumption, optic-flow sensors attract growing interest in robotics for tasks such as self-motion estimation or depth measurement. Most applications require a large number of these sensors, which involves a fai ...

Evolution of Spiking Neural Circuits in Autonomous Mobile Robots

Dario Floreano, Jean-Christophe Zufferey, Claudio Mattiussi

We describe evolution of spiking neural architectures to control navigation of autonomous mobile robots. Experimental results with simple fitness functions indicate that evolution can rapidly generate spiking circuits capable of navigating in textured envi ...

An Indoor Flying Platform with Collision Robustness and Self-Recovery

Dario Floreano, Jean-Christophe Zufferey, Adrien Briod, Adam Klaptocz

This paper presents a new paradigm in the design of indoor flying robots that replaces collision avoidance with collision robustness. Indoor flying robots must operate within constrained and cluttered environments where even nature’s most sophisticated fly ...

Testbed for Fast-Deployable Flying WiFi Networks

Dario Floreano, Bixio Rimoldi, Jean-Christophe Zufferey, Grégoire Hilaire Marie Heitz, Stefano Rosati, Alberto Jimenez Pacheco, Karol Jacek Kruzelecki

EPFL's Information Processing Group (IPG) and Laboratory for Intelligent Systems (LIS), in conjunction with SenseFly (a LIS spin-off) recently started a project aimed at developing a testbed to experiment with self-organized wireless networks carried by au ...

Steerable Miniature Jumping Robot

Dario Floreano, Jean-Christophe Zufferey, Mirko Kovac

Jumping is used in nature by many small animals to locomote in cluttered environments or in rough terrain. It offers small systems the benefit of overcoming relatively large obstacles at a low energetic cost. In order to be able to perform repetitive jumps ...

Communication-based Leashing of Real Flying Robots

Dario Floreano, Jean-Christophe Zufferey, Sabine Hauert, Severin Leven

Aerial robots are often required to remain within the communication range of a base station on the ground to exchange commands, sensor data or as a safety mechanism. For this purpose, we propose a minimal control strategy for steering flying robots using o ...

Quadrotor Using Minimal Sensing For Autonomous Indoor Flight

Dario Floreano, Jean-Christophe Zufferey, Timothy Stirling, James Roberts

This paper presents a Miniature Aerial Vehicle (MAV) capable of hands-off autonomous operation within indoor environments. Our prototype is a Quadrotor weighing approximately 600g, with a diameter of 550mm, which carries the necessary electronics for stabi ...

optiPilot: control of take-off and landing using optic flow

Dario Floreano, Jean-Christophe Zufferey, Antoine Beyeler

Take-off and landing manoeuvres are critical for MAVs because GPS-based autopilots usually do not perceive distance to the ground or other potential obstacles. In addition, attitude estimates based on inertial sensors are often perturbed by the strong acce ...

Visual autopilot for near-obstacle flight

Dario Floreano, Jean-Christophe Zufferey, Antoine Beyeler

This present invention describes a novel vision-based control strategy for autonomous cruise flight in possibly cluttered environments such as – but not limited to - cities, forests, valleys, or mountains. ...

Near-obstacle flight with small UAVs

Dario Floreano, Jean-Christophe Zufferey, Antoine Beyeler

Autonomous flight in confined or cluttered environments such as houses or urban canyons requires high manoeuvrability, fast mapping from sensors to actuators and very limited overall system weight. Although flying animals are well capable of solving this p ...

Ant-based Swarming with Positionless Micro Air Vehicles for Communication Relay

Dario Floreano, Jean-Christophe Zufferey, Sabine Hauert

Swarming without positioning information is interesting in application- oriented systems because it alleviates the need for sensors which are dependent on the environment, expensive in terms of energy, cost, size and weight, or unusable at useful ranges fo ...
