Article Title: Local Positioning System Using Flickering Infrared LEDs

doi: 10.3390/s17112518

Figure Lengend Snippet: The principle of the indoor positioning solution at a fixed height consists of two steps: (i) the calibration procedure aims at finding the parameters which minimize the quadratic error metrics between the reference position given by the Vicon system and the data provided by the sensor; and (ii) given the calibration parameters, the sole use of the sensor device connected to the shielded demodulation board allows to estimate the positions X and Y at a fixed height.

Figure Lengend Snippet: Picture of the experimental setup inside the motion capture system. The aim is to localize in 2D the mobile robot using HyperCube. The ground thruth is given by the Vicon cameras. The mecanum wheeled omni-directional robot is equipped with HyperCube, the localization coverage area is 2 m × 2 m. Two IR LEDs flickering at 5 kHz and 11 kHz were fixed on a horizontal bar placed above the robot at a height of 2 m.

Figure Lengend Snippet: ( A – C ) plots of the position and orientation of the mobile robot. The accurate measurements provided here only by means of the Vicon system provide to the sliding mode nonlinear controller the measured robot’s positions ( x , y ) and heading. The path is compared to the desired trajectory.

Figure Lengend Snippet: Plots of the position and orientation of the mobile robot. The accurate measurements provided by the Vicon system feed the sliding mode nonlinear controller. The trajectory is reconstructed using HyperCube and the IR LED that flickers at 11 kHz. The closed-loop control of the robot’s positions and heading is only based here on the measurements provided by the Vicon system.
