Niko and Max: Wall Detector for a Vision-impaired Person

Content

 Niko and Max have designed a device to detect walls or other obstacles for people with poor eyesight. If the detector gets close to a wall, a motor spins so that the sound and vibration will alert the user to the obstacle ahead. Thank you to Empow Studio Robotics Club for the inspiration (click to see their Dr. E's Human Plus MINDSTORMS project)
