High Compliant Series Elastic Actuation for the Robotic Leg ScarlETH

Roland Siegwart, Marco Hutter

This paper presents the actuation system of the robotic leg ScarlETH. It was developed specifically for a quadrupedal robot and is designed to achieve fast position control as well as accurate joint torque control. It introduces strong passive dynamics to ...

Robotique collective et auto-assemblage

Michael Bonani

We present a study of collective robotics by including a mechatronics point of view. In the field it is usually claimed that collective robots are simple and relatively cheap because they are produced in large quantities. Instead in our study we show that ...

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 ...

Control of legged locomotion using dynamical systems

Ludovic Righetti

Legged robots have gained an increased attention these past decades since they offer a promising technology for many applications in unstructured environments where the use of wheeled robots is clearly limited. Such applications include exploration and res ...

Pattern generators with sensory feedback for the control of quadruped locomotion

Auke Ijspeert, Ludovic Righetti

Central Pattern Generators (CPGs) are becoming a popular model for the control of locomotion of legged robots. Biological CPGs are neural networks responsible for the generation of rhythmic movements, especially locomotion. In robotics, a systematic way of ...

Autonomous Self-assembly in a Swarm-bot

Francesco Mondada, Michael Bonani, Roderich Gross

Multi-robot systems have been studied in tasks that require the robots to be physically linked. In such a configuration, a group of robots may navigate a terrain that proves too difficult for a single robot. On the contrary, many collective tasks can be ac ...

Wheel torque control for a rough terrain rover

Roland Siegwart, Pierre Lamon, Michel Lauria

Navigating in rough terrain is a complex task that requires the robot to be considered as a holistic system. Algorithms, which don’t consider the physical dimensions and capabilities of the mobile robot lead to inefficient motion and suffer from a la ...

PID vs LQ Control Techniques Applied to an Indoor Micro Quadrotor

Roland Siegwart

The development of miniature flying robots has become a reachable dream thanks to the new sensing and actuating technologies. Micro VTOL1 systems represent a useful class of flying robots because of their strong abilities for small-area monitoring and buil ...

Optic-flow-based steering and altitude control for ultra-light indoor aircraft

Dario Floreano, Jean-Christophe Zufferey

Our goal is to demonstrate the ability of bio-inspired techniques to solve the problem of piloting an autonomous 40-grams aircraft within textured indoor environments. Because of severe weight and energy constraints, inspiration has been taken from the fly ...

Vision-based Navigation from Wheels to Wings

Dario Floreano, Jean-Christophe Zufferey, Antoine Beyeler

We describe an incremental approach towards the development of autonomous indoor flyers that use only vision to navigate in textured environments. In order to cope with the severe weight and energy constraints of such systems, we use spiking neural control ...
