Abstract Blind people in China account for a large number of global proportion. For the domestic blind guiding dogs are expensive,
scarce and not universal, this paper proposes a cheap, practical and portable blind guiding robot to replace the blind guiding
dog. It uses the Linux (Debian release) platform Raspberry Pi as the central processing unit, uses five ultrasonic distance sensors to
collect the distance information from different angles of the forward direction. Based on the initial positioning by the sensors, the
camera further determines the obstacle position by collecting image data. The result is feed back to the blind people by vibration signal.
The function is realized in experiment environment.
