Abstract: A collision avoidance apparatus for use with an automated guided vehicle (AGV) includes: an object detection sensor assembly; a controller in electronic communication with the sensor assembly; the object detection sensor assembly configured to generate a detection signal to define a sensing region and receive a reflected detection signal; the controller configured to: process the reflected signal to detect presence of an object based on a parameter of the reflected signal, define a boundary within the sensing region, dynamically adjust the size and/or shape of the boundary, and determine if the detected object is located within the boundary.

Abstract: A method of navigating a visually impaired user, a navigation system and a guiding robot used in the system. The method includes the steps of: receiving a plurality of location referencing signals from a plurality of signal sources; processing the location referencing signals to determine a current location of the user in a predetermined area; planning an optimal path for the user to travel from the current location to a destination location; providing guiding information associated with the optimal path to the user; obtaining a travel instruction from the user to travel along the optimal path; and moving a guiding robot according to the travel instruction provided by the user along the optimal path until the next travel instruction is required to further move the guiding robot.
