1. A device, comprising:
at least one lens;
an image sensor;
a first component configured to:
obtain at least one signal from a controller;
obtain one or more signals indicative of one or more sensor measurements;
determine, based on the at least one signal and the one or more signals indicative of the one or more sensor measurements, (1) a first set of current for a first set of coils of one or more actuators and (2) a second set of current for a second set of coils of the one or more actuators for interacting with one or more magnets to move at least one of (a) the at least one lens or (b) the image sensor; and
provide the first set of determined current to the first set of coils of the one or more actuators; and
a second component configured to:
obtain, from the first component, at least one signal indicative of the second set of determined current for the second set of coils; and
provide the second set of determined current to the second set of coils of the one or more actuators.
