  We investigate the applicability of the Method of Regularized Stokeslets
(MRS) in the simulation of micro-swimmers at low Reynolds number. The chosen
model for the study is the well-known three linked spheres swimmer. We compare
our results with the lattice Boltzmann method, multiparticle collision
dynamics, a numerical solution of the Oseen tensor equation and an analytical
solution, all taken from Earl $\textit{et al.}$ [J. Chem. Phys. 126, 064703
(2007)]. The MRS is studied in detail, and our results show an excellent
agreement with the lattice Boltzmann method, and with the analytical solution
in its range of validity. We conclude that the MRS is well suited for this type
of simulation, offering advantages such as being easy to implement and to
represent complex geometries. Therefore it presents itself as a suitable
candidate for more complex simulations.
