Performance Tests for Wireless Real-Time Localization Systems to Improve Mobile Robot Navigation in Various Indoor Environments

A review on positioning techniques of mobile robots

“…Based on the fact that emitters are mounted on the mobile robot, it is possible to determine the direction of a route based on information from these sensors. The robot can also determine its position by examining the signal intensity [26]. Local localization can be achieved when appropriate sensors/cameras are deployed in a building, which transmit information to a central unit [27].…”

“…Global location determination and simple navigation thanks to extensive maps Limited range (mainly indoors) [12], [17], [28,29], [35], [47] Radio waves Medium Good accuracy, resistant to harsh environmental conditions Application of complex data processing algorithms [20][21][22][23][24][25][26], [49] Vision system High Very high accuracy, can be used virtually anywhere, ambient mapping Mainly based on artificial intelligence, so very sophisticated image recognition algorithms [9][10][11][12], [27], [41], [46] Follow Poor dirt resistance, complex information processing [9], [13], [45,46], [48] Other markers [-] Easy to find (self) robot, with known marker location High density of markers needed for decent work [10], [27], [48] 3.
