Apparatus and method for navigation based on illumination intensity
First Claim
1. An apparatus for navigation based on illumination intensity, which includes an actuator and a drive unit actuated by the actuator, the apparatus comprising:
- a photosensitive sensor sensing light;
a photosensitive sensor processor calculating an illumination intensity of the light sensed by the photosensitive sensor;
a drive unit moving the apparatus;
an actuator actuating the drive unit; and
a task manager generating data usable to move the apparatus along a trajectory of a preset target illumination intensity where the illumination intensity measured by the photosensitive sensor processor is the same as the target illumination intensity using the difference between the measured illumination intensity and the target illumination intensity, wherein the actuator uses the data generated by the task manager to actuate the drive unit.

Abstract
An apparatus and method for navigation based on the intensity of illumination. The apparatus includes: a photosensitive sensor sensing light; a photosensitive sensor processor calculating an illumination intensity of the light sensed by the photosensitive sensor; a drive unit moving the apparatus; an actuator actuating the drive unit; and a task manager generating data usable to move the apparatus along a trajectory of a preset target illumination intensity where the illumination intensity measured by the photosensitive sensor processor is the same as the target illumination intensity using the difference between the measured illumination intensity and the target illumination intensity. The actuator uses the data generated by the task manager to actuate the drive unit.
