Problems solved by technology

Today’s common ROS-based mobile robots are mostly powered by on-board batteries. If the robot needs to work for a long time, it is extremely inconvenient for the staff to load and unload the battery. Often, the smart car does not work normally due to undervoltage, resulting in a decline in service quality. Even service interruption
In addition, the existing lithium battery wireless charging modules on the market generally have the defect of low efficiency conversion

Abstract

The invention discloses a ROS-based high-efficiency wireless charging smart car with laser navigation function and a control method, which is mainly composed of a flyback power supply module, a wireless charging module, a motor drive and underlying control system, and an environment detection and algorithm implementation system . First, the wireless charging device charges the battery. After the car starts, the laser radar is used to collect information on the surrounding environment. Combined with the odometer information provided by the motor encoder, after the odometer calibration and motion distortion removal, the ROS platform in the Raspberry Pi The improved Gmapping algorithm is implemented to realize the functions of real-time positioning and map creation in an unknown environment, and then the autonomous navigation function is realized by calling the navigation function package. When the power supply voltage detection module detects that the battery voltage is insufficient, the charging point is set as the navigation target, and the function of automatically returning to the charging point for charging is realized, which greatly improves the automation level and service quality of the mobile robot.

Description

technical field [0001] The invention relates to the field of ROS intelligent cars, and particularly provides an intelligent car with a laser navigation function based on a ROS system, which can realize automatic and high-efficiency wireless charging. Background technique [0002] Nowadays, artificial intelligence and wireless charging technology are becoming more and more popular. With the development of the global trend of energy saving, cleaning and intelligence, the market potential of driverless cars and wireless charging cars is growing. Most of today's common ROS-based mobile robots are powered by on-board batteries. If the robot needs to work for a long time, it is extremely inconvenient for the staff to load and unload the battery, and the intelligent car often does not work properly due to undervoltage, resulting in a decline in service quality and even Service interruption. In addition, the existing lithium battery wireless charging modules on the market generally...
