This paper investigates the problem of straight-line path following for magnetic helical microswimmers. The control objective is to make microswimmer converge a straight line without violating step-out frequency constraint. proposed feedback solution based on an optimal decision strategy (ODS) that cast as trust-region subproblem (TRS), i.e., quadratic program over sphere. ODS-based minimizes d...

Coupled physical interactions induce emergent collective behaviors of many interacting objects. Nonreciprocity in the generates unexpected behaviors. There is a lack experimental model system that switches between reciprocal and nonreciprocal regime on demand. Here, we study magnetic microdisks breaks action-reaction reciprocity via fluid-mediated hydrodynamic interactions, Via experiments simu...
