Toward Online Probabilistic Path Replanning

Roland Siegwart, Björn Jensen, Roland Philippsen

In this talk we present work on sensor-based motion planning in initially unknown dynamic environments. Motion detection and probabilistic motion modeling are combined with a smooth navigation function to perform on-line path planning and replanning in clu ...

The WalkTrainer™: A Robotic System for Walking Rehabilitation*

Reymond Clavel, Mohamed Bouri, Yves Stauffer, Patrick Métrailler, Carl Schmitt, Yves Allemand

Robots are excellent tools for providing motion. Their motion is precise, stiff and as repeatable as we need. This led the Swiss Foundation for Cyberthosis (SFC) to exploit robotics jointly with the muscle electrostimulation as intelligent rehabilitation d ...

3D SLAM using Planar Segments

Roland Siegwart, Jan Weingarten

This paper presents an improved feature-based 3D SLAM approach for a mobile robot equipped with a rotating laser scanner. The features are represented within the SPmodel, with associated planar segment information based on decimated triangle sets. An Exten ...
