Efficient Adaptive Carrier Tracking for Mars to Earth Communications During Entry, Descent and Landing

Ali H. Sayed

In the Mars rover missions the signals transmitted back to Earth travel under low SNR conditions in highly non-stationary channels [1, 2]. During the entry, descent and landing phase (EDL), the spacecraft high dynamics yields severe Doppler effects. We pro ...

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 ...

Velocity Scheduling Controller for a Nonholonomic Mobile Robot

Dominique Bonvin, Philippe Müllhaupt, Davide Buccieri

An improvement over classical dynamic feedback linearization for the control of a nonholonomic mobile robot is proposed. The use of a state extension of higher dimension than in the case of dynamic feedback linearization helps reject constant disturbances ...

Comprehensive Locomotion Performance Evaluation of All-Terrain Robots

Roland Siegwart

Information about the locomotion performance of known rovers is sparse. A comprehensive evaluation of wheeled passive systems is presented in this work. It is based on a static 2D approach that includes optimization of the wheel torques in order to minimiz ...

Results on Range Image Segmentation for Service Robots

Roland Siegwart

This paper presents an experimental evaluation of a plane extraction method using various line extraction algorithms. Four different algorithms are chosen, which are well known in mobile robotics and computer vision. Experiments are performed on two sets o ...

Investigation of a Cable Transmission for the Actuation of MR Compatible Haptic Interfaces

Hannes Bleuler, Dominique Chapuis, Roger Gassert, Etienne Burdet, Ganesh Gowrishankar

This paper investigates a cable transmission to remotely actuate MR compatible robots over a distance of several meters. Such a transmission could be an interesting solution for haptic interfaces for neuroscience studies performing force feedback during fu ...

Adaptive Carrier Tracking for Direct-To-Earth Mars Communications

Ali H. Sayed

We propose a robust and low complexity scheme to estimate and track carrier frequency from signals traveling under low SNR conditions in highly non-stationary channels. These scenarios arise in planetary exploration missions subject to high dynamics, such ...

3D position tracking for all-terrain robots

Pierre Lamon

Rough terrain robotics is a fast evolving field of research and a lot of effort is deployed towards enabling a greater level of autonomy for outdoor vehicles. Such robots find their application in scientific exploration of hostile environments like deserts ...

Toward a person-follower robot

Solaiman Shokur

In this article we described the attempt to build a robot able to locate and follow an human target moving in a domestic environment. After a brief review of the state of the art in relative location technologies, we described our approach that aims to dev ...

EKF-based 3D SLAM for Structured Environment Reconstruction

Roland Siegwart, Jan Weingarten

This paper presents the extension and experimental validation of the widely used EKF1-based SLAM2 algorithm to 3D space. It uses planar features extracted probabilistically from dense three-dimensional point clouds generated by a rotating 2D laser scanner. ...
