Abstract

The invention provides an electronic seeing-eye dog robot which is composed of a mechanical portion and an electronic portion. The mechanical portion comprises a vehicle body, a steering engine, a steering engine connecting mechanism, a direction wheel, an orientation wheel, a rotational joint, a hand pushing rod and an antenna mast. The electronic portion comprises an infrared sensor array, a voice module, a photoelectric switch, a geomagnetic sensor, an accelerometer module, a remote control receiving circuit, a central processing unit, a circuit base plate, a voltage stabilizer, a serial port circuit, a GPS module, a loudspeaker, a nickel-metal hydride battery, a remote controller, a camera and a GPS signal receiver. Autonomous navigation can be carried out through satellite positioning, course correction, posture detection and sidewalk line searching, the operation is carried out through remote control, related navigation information is broadcast through voice, the robot can automatically walk around a barrier, and the navigation service can be provided for a blind person or a visually-impaired person in the outdoor environment.

Description

technical field [0001] The invention relates to an electronic guide dog robot, in particular to an electronic guide dog robot with electromechanical integration, multi-sensor fusion, automatic navigation and control. Background technique [0002] There are 30 million blind people in the world, including 5 million blind people in China. my country is the country with the largest number of blind people in the world. There are still a considerable number of people with visual impairment. Blindness and weak vision have greatly affected the normal life and work of these people. The cost of training a guide dog is more than 300,000 yuan, which is difficult for a normal family to bear the financial burden. Moreover, the training period of a guide dog is relatively long and the service life is relatively short. Therefore, the development of guide dog robot has very practical significance and wide application. [0003] According to relevant information, the current research and appl...
