  In this work, the orientation adapter, a species of active particles that
adapt their direction of motion from the other active particles, is introduced.
The orientation adapters exist besides the usual Vicsek-like particles; both
are self-driven, however, follow different interaction rules. We have studied
the dynamics in high speed of the particles keeping dissimilar speeds for these
different species. The effect of orientation adapters on the collective
behaviour of the system is explored in this model. The orientational
order-disorder phase transition is mainly studied in such systems. First, for
equal density of both species, when the adapter speed $v_a=1.2v_0$ and usual
particles speed $v_0=1.0$, both adapters and the usual particles form dense
travelling bands and move in the same direction. Near the transition point,
such bands appear and disappear over time, giving rise to the co-existence of
two phases. The adapters and the usual particles both undergo a discontinuous
transition. The nature of the transition is further confirmed by the existence
of hysteresis in the order parameter under a continuously varying noise field.
However, when the adapter velocity becomes much higher than the usual SPPs $v_a
\approx 7v_0$, the formation of travelling bands disappears from the system,
and the transition becomes continuous. The density ratio is also varied,
keeping the velocities constant, and the phase transition is studied. For a
high adapter velocity with $v_a=10v_0$, the continuous transition is found with
low-density values of the adapters. The critical exponents related to the
continuous transition are also determined.
