Overview of Robin, a wearable echolocation device designed to aid navigation and perception for people who are blind or have low vision. A mannequin wears the headset, which emits ultrasound pulses toward a chair, records the reflected echoes, and slows them down for playback in audible frequencies. A web app lets users customize the signal parameters.
