DESCRIPTION:Biological and bio-inspired motility at microscopic scales: lo
 comotion by shape control\n\nAntonio DeSimone\nThe BioRobotics Institute\,

 nLocomotion strategies employed by unicellular organism are a rich source 
 of inspiration for studying mechanisms for shape control. \nIn fact\, in a
 n overwhelming majority of cases\, biological locomotion can be described 
 as the result of the body pushing against the world\, by using shape chang
 e. \nMotion is then a result Newton’s third and second law: the world re
 acts with a force that can be exploited by the body as a propulsive force\
 , which puts the body into motion following the laws of mechanics. \nStrat
 egies employed by unicellular organisms are particularly interesting becau
 se they are invisible to the naked eye\, and offer surprising new solution
 s to the question of how shape can be controlled.\n\nIn recent years\, we 
 have studied locomotion by shape control using a variety of methods: model
 ling\, theory\, and numerical simulation [1-5]\, observations at the micro
 scope [4\,5]\, manufacturing of prototypes [3]. \nWe will survey our recen
 t findings within this stream of research.\n\nReferences\n[1] Arroyo\, M.\
