DESCRIPTION:Speaker: Giovanni Volpe\nhosted by Scott Waitukaitis\nAbstract:
  In the last 20 years\, active matter has been a very successful research 
 field\, bridging the fundamental physics of nonequilibrium thermodynamics 
 with applications in robotics\, biology\, and medicine. It deals with acti
 ve particles\, which\, differently from passive Brownian particles\, can h
 arness energy to generate complex motions and emerging behaviors. Most ac
 tive-matter experiments are performed with microscopic particles and requi
 re the use of advanced microfabrication and microscopy techniques. Here\, 
 we propose some macroscopic experiments with active matter employing comme
 rcially available toy robots\, i.e.\, the Hexbugs. We demonstrate how they
  can be easily modified to perform regular and chiral active Brownian moti
 on. Then\, we show that they can interact with passive objects present in 
 their environment and\, depending on their shape\, set them in motion and 
 rotation. Furthermore\, we show that obstacles in the environment can be 
 employed to sort them based on their motility and chirality. Finally\, we 
 demonstrate the emergence of Casimir-like activity-induced attraction betw
 een planar objects in the presence of active particles in the environment.
