SWARM-BOT: From Concept to Implementation

Dario Floreano, Francesco Mondada, André Guignard, Michael Bonani, Michel Lauria

This paper presents a new robotic concept, called SWARM-BOT, based on a swarm of autonomous mobile robots with self-assembling capabilities. SWARM-BOT takes advantage from collective and distributed approaches to ensure robustness to failures and to hard e ...

Specification of Replication Techniques, Semi-Passive Replication, and Lazy consensus*

André Schiper, Xavier Défago

This paper brings the following three main contributions: a hierarchy of specifications for replication techniques, semi-passive replication, and Lazy Consensus. Based on the definition of the Generic Replication problem, we difine two families of replicat ...

SWARM-BOT: A Swarm of Autonomous Mobile Robots with Self-Assembling Capabilities

Dario Floreano, Francesco Mondada, André Guignard, Mirco Dorigo, Luca Maria Gambardella

We present a new robotic concept, called SWARM-BOT, based on a swarm of small and simple autonomous mobile robots called S-BOTs. S-BOTs have a particular assembling capability that allows them to connect physically to other S-BOTs and form a bigger robot e ...

X-ability: A Theory of Replication

Rachid Guerraoui

This paper presents x-ability (Exactly-once-ability): a correctness criteria for replicated services. X-ability provides the illusion that the actions executed by a replicated service are executed exactly-once, even if these actions have been actually exec ...

Democratrizing the Parliament

Rachid Guerraoui

This paper presents a replication algorithm that implements a highly-available, non-deterministic state machine. Our algorithm generalizes the Paxos parliament algorithm of Lamport to cope with non-deterministic computations, while preserving its nice resi ...

Understanding replication in databases and distributed systems

André Schiper, Matthias Wiesmann, Fernando Pedone

Replication is an area of interest to both distributed systems and databases. The solutions developed from these two perspectives are conceptually similar but differ in many aspects: model, assumptions, mechanisms, guarantees provided, and implementation. ...

All-photoplastic, soft cantilever cassette probe for scanning force microscopy

Nico de Rooij, Peter Vettiger, Grégoire Genolet

The fabrication and application of photoplastic scanning force microscopy (SFM) probes has been demonstrated. Simple molding and replication techniques, inexpensive photoplastic material, reusable molds and several layers per probe make it a very attractiv ...

Oligomerization of activated D- and L-guanosine mononucleotides on templates containing D- and L-deoxycytidylate residues

The oligomerization of activated D- and L- and racemic guanosine-5'-phosphoro-2-methylimidazole on short templates contg. D- and L-deoxycytidylate has been studied. Results obtained with D-oligo(dC)s as templates are similar to those previously reported fo ...
