Calibrating a 4-wheel mobile robot
When a mobile robot is constructed the odometry must be calibrated. Calibrating a 4-wheel robot requires the accurate measurement of steering angle as well as translation and rotation. Some measurements are made with a tape measure and some with ultrasonic sensors. The measurements are used to determine the parameters of the odometry calibration matrix

Speed Control for Leader-Follower Robot Formation Using Fuzzy System and Supervised Machine Learning
Mobile robots are endeavoring toward full autonomy. To that end, wheeled mobile robots have to function under non-holonomic constraints and uncertainty derived by feedback sensors and/or internal dynamics. Speed control is one of the main and challenging

An Innovative Drive for Wheeled Mobile Robots [PDF]
Introduced In this work is an innovative drive for wheeled mobile robots, that is based on two identical, coaxial wheels, independently driven by two identical motors. The common axis is capable of rotating about a vertical axis. The drive, termed dual-wheel transmission (DWT), is composed of two identical epicyclic gear trains, lying at two different ...

Hybrid Control Design for a Wheeled Mobile Robot [PDF]
We present a hybrid systems solution to the problem of trajectory tracking for a four-wheel steered four-wheel driven mobile robot. The robot is modelled as a non-holonomic dynamic system subject to pure rolling, no-slip constraints. Under normal driving conditions, a non-linear trajectory tracking feedback control law based on dynamic feed-back ...

Electrical resistivity change upon annealing is introduced as a rapid descriptor for identifying high glass‐forming ability in metallic glasses. High‐throughput combinatorial thin‐film libraries reveal that compositions exhibiting small resistivity changes correspond to sluggish crystallization behavior and known bulk metallic glass regions, enabling ...

Component-Based Detailed Modeling of a Small Wheeled Mobile Robot with Indispensable Nonlinearities
This paper provides a component-based modeling of a small wheeled mobile robot with indispensable nonlinearities. We obtain a model of each fundamental component for a wheeled mobile robot, and then we provide the whole robot model by integrating the ...
