1. A mobile robot, comprising:
a first light source, arranged on a front surface of the mobile robot and configured to project a transverse light section toward a moving direction;
an optical sensor, arranged on the front surface of the mobile robot and below the first light source, and configured to capture a first image frame toward the moving direction, and comprising:
a pixel array, a lower part of the pixel array being coated with an IR pass filter and an upper part of the pixel array not being coated with the IR pass filter; and
a processor, electrically coupled to the first light source and the optical sensor, and configured to
perform range estimation using pixel data corresponding to the lower part of the pixel array, and
perform visual simultaneous localization and mapping (VSLAM) using pixel data corresponding to the upper part of the pixel array.
