ROS-based service robot and voice interaction navigation method thereof

Abstract

The invention relates to an ROS-based service robot and a voice interaction navigation method thereof. The service robot comprises a mobile chassis, a shell, a support frame and two PCs, wherein the mobile chassis comprises a driven guiding support wheel set, a motor module, a gyroscope, an electronic compass, a power supply module and an emergency obstacle avoidance module; a touch screen, a screen switcher and a data acquisition module are mounted on the shell; the bottom PC is provided with ROS; and the top PC is provided with android. The voice interaction navigation method includes the following steps: the service robot acquires environment information, establishes a two-dimensional map, acquires a target pose from the map, sets a name on the target pose, adds the target pose into a task target set, and then adds the task target set to a voice interaction navigation module; and the voice interaction navigation module is started, an initial position is set, a user enters a desiredlocation in the voice interaction end of the android, the android recognizes a keyword, and then sends the keyword to the voice interaction navigation module as a target location through a serial port, and a path planning module and the emergency obstacle avoidance module are used to complete the navigation task.

Description

technical field [0001] The invention belongs to the technical field of service robots, in particular to a ROS-based service robot and a voice interactive navigation method thereof. Background technique [0002] In recent years, with the rapid development of science and technology and the needs of society, service robot technology has also been continuously developed. Service robots have gradually entered various fields of daily life such as home use, business, tour guide, medical treatment, education, and security. In today's society where the population is aging and the pressure of life is increasing, people need service robots to provide better services. According to the current market data, most of the household service robots are cleaning robots and weeding robots. Most of them can only complete tasks according to pre-set orders, lack the ability to solve emergencies, and even lack rich human-computer interaction functions. In addition, the food delivery robots currentl...

AI Technical Summary

Problems solved by technology

According to the current market data, most of the household service robots are cleaning robots and weeding robots. Most of them can only complete tasks according to pre-set orders, lack the ability to solve emergencies, and even lack rich human-computer interaction functions. In addition, the food delivery robots currently in use need to walk along the pre-set magnetic navigation bar during the food delivery process. The autonomy in the navigation process is low, and most of them can only complete one-to-one tasks.
