SLAMICP Library: Accelerating Obstacle Detection in Mobile Robot Navigation via Outlier Monitoring following ICP Localization,
Sensors 2023, 23, 6089.This work proposes to speed up the obstacle detection process by directly monitoring outliers (discrepant points between the LIDAR scans and the full map) spotted after Iterative Closest Point (ICP) matching instead of spending time performing an isolated task to re-analyze the LIDAR scans to detect those discrepancies.
This paper features the SLAMICP Library: a Free and Open Source library that we developped to implement ICP matching returning the outliers detected and other internal matching parameters during mobile robot navigation.
Point Cloud application example of the SLAMICP Library
Mobile robot following a planned trajectory: the blue dots depict the 2D map of the facility;
the dotted cyan points depict the planned trajectory and the green arrow the final position and orientation that must be achieved by the mobile robot;
the solid olive line depict the real trajectory followed by the mobile robot and the brown arrow depit ist current position and orientation;
the red points are the outliers detected after ICP matching that (in this case) reveal one side of an obstacle placed in the corridor.

Optimal PID Control of a Brushed DC Motor with an Embedded Low-Cost Magnetic Quadrature Encoder for Improved Step Overshoot and Undershoot Responses in a Mobile Robot Application,
Sensors 2022, 22(20), 7817.This paper describes the optimization of the PID control of a brushed DC motor (BDCM) with an embedded low-cost magnetic quadrature encoder. This paper demonstrates empirically that the feedback provided by low-cost magnetic encoders produces some inaccuracies and control artifacts that are not usually considered in simulations, proposing a practical optimization approach in order to improve the step overshoot and undershoot controller response.
