Robotic Guide Dog

A mobile robot — typically a quadruped platform — designed to provide navigation and obstacle-avoidance support for blind and low-vision users, filling a role analogous to that of a trained guide dog. Research prototypes have explored handler interaction, leash-based coupling, auditory and haptic feedback, and integration with orientation-and-mobility training. Robotic guide dogs are motivated by the scarcity, cost, and allergy limitations of trained guide dogs, but face open challenges around public acceptance, social signaling (a live dog communicates attention and intent in ways a robot does not), reliability in unstructured outdoor settings, and the cultural and relational role that living guide dogs play in users' lives.
