Manipulation of the MDA in 2D vascular network model. Translational locomotion of the MDA with double spirals in the 2D vascular network model placed: (a) on the horizontal plane and (b) on the vertical plane. (i) and (ii) show selective movement of the MDA toward 45° and 60° channels, respectively, by manipulation using EMA. Scale bar represents 10 mm. The MDA selected and moved along the desired path via the junctions of multiple channels with different angles.
