DESCRIPTION:Speaker: Alexandre Pacheco\n\nAbstract:\n	A robot swarm is a typ
 e of mobile multi-robot system whose design is\n	inspired by the complex so
 cieties of eusocial insects: while an\n	individual ant cannot accomplish mu
 ch\, colonies composed of millions\n	have adapted social behaviours that al
 low them to thrive in all\n	corners of our planet.\n\nLike their natural co
 unterparts\, swarm robotics systems avoid\n	centralized control architectur
 es\, and instead promote local\n	communications and individual decision mak
 ing. These design choices\n	enable a system that is scalable\, flexible and
  fault-resistant by\n	redundancy. Despite this\, recent research has shown 
 that robot swarms\n	are prone to Byzantine faults (e.g.\, when communicatio
 n channels are\n	tampered\, or when faults from one robot can propagate to 
 its peers).\n	In the absence of supervision or central control\, robot swar
 ms that\n	operate in the real-world may be prone to failures caused by faul
 ts\,\n	attacks or exploitation.\n\nBlockchain technology is a new research 
 field that combines concepts\n	from micro-economics and cryptography to add
 ress Byzantine-fault\n	tolerance in peer-to-peer internet networks. Similar
 ly to the human\n	agents in blockchain networks\, robots can exhibit a wide
  variety of\n	behaviors that can be classified as Byzantine. In our researc
 h\, we\n	consider that robots may be faulty (due to hardware malfunctions)\
 ,\n	malicious (due to tampering from adversaries) or non-altruistic\n	(becau
 se they have been programmed by self-motivated individuals).\n\nIn this pr
 esentation I will provide a short introduction to swarm\n	robotics and bloc
 kchain technology while diving deeper into the\n	'oracle problem': how to s
 ecurely validate the information that is\n	proposed by potentially Byzantin
 e robots in a decentralized way.\n\n \n\nBio:\n	Alexandre Pacheco is a Ph.D
 . student at IRIDIA\, the Artificial\n	Intelligence research laboratory of 
 the Université Libre de Bruxelles\,\n	under the supervision of Professor Ma
 rco Dorigo. Before that he\n	completed his BSc. degree in Mechanical engine
 ering at Instituto\n	Superior Técnico\, in Lisbon\, and MSc. degree in Syst
 ems and Control\n	engineering at the Technical University of Delft where he
  graduated in\n	2018. Throughout 2017 he was a control systems intern at In
 telligent\n	Systems Division at the NASA Ames Research Center.\n	\n	Alexandre
 's PhD research combines swarm intelligence\, blockchain\n	technology and e
 conomics\, investigating how complex swarm behaviours\n	emerge from the eco
 nomic interactions of self-interested robots\, and\n	how a Byzantine-tolera
 nt swarm operation can be achieved using\n	crypto-economic mechanisms.\n\n
