Coverage with a Team of Wheeled Mobile Robots
Journal of Intelligent & Robotic Systems, 2014This article presents a control system enabling coverage of a prescribed ground area by a team of wheeled mobile robots. The control system relies on equal balancing of the costs among the wheeled robots. Cost balancing leverages the intuition that a healthy neighbor could help a degraded robot to carry out its monitoring task simply by moving slightly

Synchronization of mobile robot's actuated wheels
SPIE Proceedings, 2015Quintic Bezier splines are capable of dynamic adaptive path changes in curvature continuous fashion. This paper presents a general purpose method for synchronizing the turning and steering rates of a mobile robot’s wheels according to a given velocity profile when traversing a quintic Bezier spline or some other differentiable parametric curve.

Robust Control Laws for Wheeled Mobile Robots
IFAC Proceedings Volumes, 1996The paper deals with feedback control of wheeled mobile robots. The proposed controller is based on a tracking scheme where the real robot tracks a fictitious reference one with equivalent kinematical properties. A solution to the parking problem is derived from the basic tracking scheme by considering a reference vehicle which converges to the desired

Comparative Analysis of Mobile Robot Wheels Design
2018 11th International Conference on Developments in eSystems Engineering (DeSE), 2018© 2018 IEEE. This paper considers a design of wheeled mobile robot platforms. Each platform is designed for a set of specific tasks and thus is supposed to work in previously known general conditions of its environment. A robotic system could be constructed as a holonomic or a non-holonomic system, which directly correlates with a type of its wheels ...

A motion control of a two-wheeled mobile robot
IEEE SMC'99 Conference Proceedings. 1999 IEEE International Conference on Systems, Man, and Cybernetics (Cat. No.99CH37028), 2001We discuss the motion control of a two-wheeled mobile robot. In the design of a controller for the system, a kinematic model is usually used; the wheels do not skid at all and the mobile robot is regarded as a 3D 2-input nonholonomic system without drift. Many controllers based on the kinematic model have been proposed.

Wheeled Mobile Robots: A review
IEEE Latin America Transactions, 2012Robotics is a fast developing and exciting field with multiple applications which span from robot manipulators to mobile robots. This paper presents a literature review on wheeled mobile robots. We point out the main considerations to be taken into account when designing this class of robots.

While the classical holonomic constraints limit the freedom of motion through the position variables, and thus simultaneously through the velocity variables, the non-holonomic constraints, realized purely mechanically via (for example) rolling wheels, lead to a restriction of the velocities only, not of the positions.

Design a Transformable Wheel for Enhancing Mobility of 4-Wheeled Mobile Robot
Applied Mechanics and Materials, 2015This paper proposes a design of transformable wheel for enhancing mobility. Mobility evaluation is performed by mechanical theories as stability margin and obstacle overcoming and its calculating methods are used for simulations. A feasibility of suggested transformable wheel is investigated by simulations.

Fuzzy Parking Manoeuvres of Wheeled Mobile Robots
NAFIPS 2007 - 2007 Annual Meeting of the North American Fuzzy Information Processing Society, 2007This work deals with the parking manoeuvres problem for a wheeled mobile robot (WMR). The robot has the same non-holonomic kinematic constraint that has a car vehicle. This constraint makes the robot having its direction always tangent to the trajectory. Two sub-cases of parking problems are considered.
