Query: Controllability of a bent 3-link magnetic microswimmer   - In this paper, we focus on a variant of a 3-link magnetic microswimmer
which consists of three rigid magnetized segments connected by two torsional
springs. In particular, we assume that one of the springs is twisted so that
the swimmer is not aligned at rest. By acting on it with an external magnetic
field, the swimmer twists and moves through the surrounding fluid. By
considering the external magnetic field as a control function, we state a local
partial controllability result around the equilibrium states. Then, we propose
a constructive method to find the magnetic field that allows the swimmer to
move along a prescribed trajectory. Finally, we show numerical simulations in
which the swimmer moves along a prescribed path.
