Abstract: Disclosed is a robot for use in acquiring high resolution imaging data. The robot is particularly suited to acquire images indoors—for example in a retail or warehouse premises. Acquired images may be analyzed to identify inventory and the like. The robot includes a conveyance for moving the robot along a path. The robot captures, using a line scan camera, a series of images of objects along the path as the robot moves. A controller controls the locomotion of the robot and the acquisition of individual images through the camera. Each individual acquired image of the series of images has at least one vertical line of pixels. The series of images may be combined to create a combined image having an expanded resolution. The number of pixels per linear unit of movement may be controlled by the controller, in dependence on the speed of motion of the robot.
