  We numerically investigate the transport of kinks in a ratchet cellular
automata geometry for colloids interacting with dynamical traps. We find that
thermal effects can enhance the transport efficiency in agreement with recent
experiments. At high temperatures we observe the creation and annihilation of
thermally induced kinks that degrade the signal transmission. We consider both
the deterministic and stochastic cases and show how the trap geometry can be
adjusted to switch between these two cases. The operation of the dynamical trap
geometry can be achieved with the adjustment of fewer parameters than ratchet
cellular automata constructed using static traps.
