A robot includes a gripping member configured to move and pick up the object, a camera affixed to the gripping member such that movement of the gripping member causes movement of the camera, the camera configured to measure and store data related to intensity of light and direction of light rays within the environment, an image processing module configured to process the data to generate a probabilistic model defining a location of the object within the environment, and an operation module configured to move the gripping member to the location and pick up the object.
