Abstract:
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 to sense light; a photosensitive sensor processor to calculate an illumination intensity of the light sensed by the photosensitive sensor; a drive unit to move the apparatus; an actuator to actuate the drive unit; and a task manager to generate data usable to move the apparatus along a trajectory of a target illumination intensity, where a measured illumination intensity calculated by the photosensitive sensor processor is the same as a preset target illumination intensity, using the difference between the measured illumination intensity and the preset target illumination intensity, wherein the actuator uses the data generated by the task manager to actuate the drive unit, and wherein the task manager generates data usable to move the apparatus to a location where the illumination intensity is the highest when the number of collisions with an obstacle on the movement path exceeds a predetermined threshold.
