Indoor Positioning Technology and Control of Mobile Home Service Robot

Abstract

With the rapid development of the market economy, location information services have shifted from outdoor to indoor, requiring higher system accuracy. Indoor positioning and control is an indispensable technical support for mobile home service robots to perform system tasks, and this technology is also an important parameter that marks the level of intelligence of a home service robot. However, in indoor places, how to obtain the target node location information timely and accurately and how to control and path planning should be the first issues to be considered in the design of home robots at this stage. This article gave a brief overview of the current indoor positioning technology and control, analyzed the more widely and frequently used indoor positioning methods, and deeply studied the ultrasonic positioning technology. On this basis, a mobile home service robot system was designed, and simulation experiments were carried out, respectively, to test the receiving time and arrival time of the node signal, the node positioning accuracy, the optimal degree of route planning, and the absolute and relative errors of navigation and path estimation. The experimental results showed that the accuracy of the robot system positioning proposed in this article reached more than 80%, and the relative error was only 4.21%, which verified its feasibility and effectiveness in practical applications. Popularizing it in the market can effectively improve the system performance and intelligence of home service robots.

“…With the gradual maturity of today's robotics, mobile robots are widely used in the service industry [1] , industrial manufacturing [2] and other research fields due to their high mobility and flexibility. Among them, path planning is a key technology for autonomous navigation of mobile robot.…”

An Ensemble Filter for Indoor Positioning Technology of Mobile Home Service with Agile iBeacon Deployment

“…Figure4shows the test findings for receiving signals and arrival time in spaces 1 and 2. It demonstrates how the mobile home service robot is ideal for gathering signals from all nodes in the three-dimensional space with only a tiny bit of trouble setting boundaries[12,13]. The time it takes to receive a signal varies between 1.89 seconds and 2.67 seconds, with the distance variable being the main cause of both extremes.…”
