  In the above mentioned note (<hal-01145537>, <arXiv:1506.05918>, published in
IEEE Trans. Autom. Cont., 2017), the first and fourth authors proved a local
controllability result around the straight configuration for a class of
magneto-elastic micro-swimmers.That result is weaker than the usual small-time
local controllability (STLC), and the authors left the STLC question open. The
present addendum closes it by showing that these systems cannot be STLC.
