The concept of the mobilized domain: how it can explain and predict the forces exerted by a cohesive granular avalanche on an obstacle.

Christophe Ancey, Johan Alexandre Philippe Gaume, Betty Sovilla, Michael Lukas Kyburz

The calculation of the impact pressure on obstacles in granular flows is a fundamental issue of practical relevance, e.g. for snow avalanches impacting obstacles. Previous research shows that the load on the obstacle builds up, due to the formation of forc ...

Design space exploration through force-based grammar rule

Corentin Jean Dominique Fivet, Ioannis Mirtsopoulos

Design exploration frames the process of understanding design as a challenge and helps taming its complexity. It is a creative, but also paramount, process, that flourishes diversity, emergence and variability. The approaches used during this exploration s ...

Memory of Motion for Warm-Starting Trajectory Optimization

Sylvain Calinon, Emmanuel Pignat, Antonio Paolillo, Teguh Santoso Lembono

Trajectory optimization for motion planning requires good initial guesses to obtain good performance. In our proposed approach, we build a memory of motion based on a database of robot paths to provide good initial guesses. The memory of motion relies on f ...

X-Shells: A new class of deployable beam structures

Mark Pauly, Florin Isvoranu, Mina Konakovic Lukovic, Etienne Bouleau

We present X-shells, a new class of deployable structures formed by an ensemble of elastically deforming beams coupled through rotational joints. An X-shell can be assembled conveniently in a flat configuration from standard elastic beam elements and then ...

Autonomous Exploration for Radioactive Hotspots Localization Taking Account of Sensor Limitations

Francesco Mondada, Hadi Ardiny, Stefan John Witwicki

Effective radioactive hotspot localization and detection is limited by sensor characteristics (i.e., the long acquisition time and poor angular resolution AR of a gamma camera) that significantly degrade the performance of autonomous exploration in terms o ...

Delicate yet strong: characterizing the electro-adhesion lifting force with a soft gripper

Herbert Shea, Jun Shintake, Vito Cacucciolo

Compliant grippers are one of the most promising soft robotic devices for industrial tasks. Soft grippers dramatically simplify grasping control because the gripper automatically conforms to the object's shape. A common limitation of soft structures is tha ...

RAQ: Relationship-Aware Graph Querying in Large Networks

Akhil Arora, Arnab Bhattacharya

The phenomenal growth of graph data from a wide variety of real-world applications has rendered graph querying to be a problem of paramount importance. Traditional techniques use structural as well as node similarities to find matches of a given query grap ...
