Embodiment Construction

[0056] The robot positioning device based on sound guidance of the present invention is composed of the following units:

[0057] The pronunciation unit receives the control signal sent by the first control unit and sends out the audio signal;

[0058] The pickup unit receives the audio signal sent by the pronunciation unit;

[0059] The first automatic control unit controls the pronunciation unit to send an audio signal, receives the plane coordinate information of the robot transmitted by the first wireless communication unit through the second wireless communication unit in real time, and performs corresponding processing on the information, and drives the steering wheel according to the processing result. The unit outputs steering drive control signals;

[0060] The second automatic control unit receives the audio signal collected by the sound pickup unit in real time, and processes the signal information to obtain the plane coordinate information of the position of the r...

Abstract

The invention discloses a robot positioning device and its positioning method based on sound guidance, which includes a sounding unit, a sound pickup unit, a first automatic control unit, a second automatic control unit, a steering drive unit, a first wireless communication unit and a second Wireless communication unit; the pronunciation unit, the first wireless communication unit, and the steering drive unit are respectively connected to the first automatic control unit; the sound pickup unit, the second wireless communication unit are respectively connected to the second automatic control unit; positioning method: pronunciation unit Send an audio signal to the pickup unit; the pickup unit sends it to the second automatic control unit; the second automatic control unit processes the signal and sends it to the first automatic control unit; the first automatic control unit processes the information and sends the steering to the steering drive unit Drive control signal; the steering drive unit controls the movement of the robot. The invention is based on sound guidance and positioning, has few sensors, fast positioning speed and high precision, and conveniently solves the positioning problem of the robot.

Description

technical field [0001] The invention belongs to the field of robot intelligent control, and relates to a robot positioning device, in particular to a voice-guided robot positioning device and a positioning method thereof. technical background [0002] At present, the positioning and tracking of robots is mainly realized by visual positioning and auditory positioning. Since the visual field is limited to less than 180° and cannot pass through non-opaque obstacles, when the target is outside the scope of the robot's visual field or behind an opaque object, relying solely on robot vision to obtain the outside world The information becomes very difficult and the positioning accuracy is not very high. The auditory information is one-dimensional on the time axis and non-directional in space. When the audio signal is generated, its energy propagates radially along the spherical surface in the air, and the sensor in any direction can receive the sound wave, and the sound wave has ...
