Security and protection robot

Abstract

The invention provides a security and protection robot. A front wheel steering and back wheel driving structure manner is adopted, a multi-sensor data fusion positioning method is used for motion, a vehicle frame, a front wheel assembly, a back wheel assembly and a steering mechanism are included, the front wheel assembly and the back wheel assembly are supported to the front end and the back endof the vehicle frame correspondingly, and the steering mechanism is installed on the lower surface of the vehicle frame. According to a steering chassis, position allocation of front and back wheels and a steering device meets the ackerman corner principle, it can be guaranteed that all wheels do pure rolling during steering, the steering force is reduced, and the motor power is reduced; and meanwhile, a binocular camera, a laser radar and a differential GPS are used in cooperation, and more accurate outdoor positioning information is provided.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a security robot for community patrolling, guiding, interaction, monitoring and inspection and a positioning method thereof. Background technique [0002] At present, robot applications have penetrated into various industries, but due to factors such as cost and safety, the market has not yet been fully opened, but the state has begun to give strong support from policies. For example, the core of the previously released "Industry 4.0" strategy is to realize real-time communication, mutual recognition and effective communication of people, equipment and products, so as to build a highly flexible, personalized and digital intelligent manufacturing model. [0003] 1) The security personnel are old, have low education level, are slow to respond to early warning, and have relatively high mobility; [0004] 2) There is a large gap in security personnel in places where human patrols are...

AI Technical Summary

Problems solved by technology

[0003] 1) The security personnel are old, have low education level, are slow to respond to early warning, and have relatively high mobility;

[0004] 2) There is a large gap in security personnel in places where human patrols are difficult, such as harsh environments, patrols in cold and low-temperature areas in the north, on-duty guards on railway bridges, and patrols in key protected areas;

[0005] 3) The demand for security personnel is increasing year by year, the actual number of employees is less than 75%, and the gap has reached millions

[0007] Existing robots use high-power motors, which are costly and do not have a shock absorbing system, which makes the robot bump more when it crosses obstacles, and the vibration of the electric control is larger, making it easy to loosen and have poor contact. In addition, the images transmitted by the camera unstable

Secondly, most of the existing robot positioning methods use multiple two-dimensional sensors to obtain environmental information. The inevitable defects of the combined use of multiple two-dimensional sensors lead to the low positioning accuracy of the robot, and the effect of such robots in navigation and positioning is relatively small Poor, and insufficient scalability; the cost of 3D lasers to obtain 3D environmental information is high
