A new localization approach to increase the navigational
capabilities and object manipulation of autonomous
mobile robots, based on an encoded infrared sheet of light
beacon system, which provides position errors smaller than
0.02m is presented in this paper. To achieve this minimal
position error, a resolution enhancement technique has
been developed by utilising an inbuilt odometric/optical
flow sensor information. This system respects strong low
cost constraints by using an innovative assembly for the
digitally encoded infrared transmitter. For better guidance
of mobile robot vehicles, an online traffic signalling capability
is also incorporated. Other added features are its less
computational complexity and online localization capability
all these without any estimation uncertainty. The
constructional details, experimental results and computational
methodologies of the system are also described
