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

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.

Kinematic modeling of wheeled mobile robots
Journal of Robotic Systems, 1987AbstractWe formulate the kinematic equations of motion of wheeled mobile robots incorporating conventional, omnidirectional, and ball wheels.1 We extend the kinematic modeling of stationary manipulators to accommodate such special characteristics of wheeled mobile robots as multiple closed‐link chains, higher‐pair contact points between a wheel and a ...

Robust controller for wheeled mobile robots
2012 American Control Conference (ACC), 2012A guidance and control system has been developed for the autonomous operation of under-actuated mobile robots. The guidance system is based on the concepts of the line-of-sight (LOS) with the acceptance radius. It empowers the controller to simultaneously deal with the cross-track error while yielding the proper orientation of the robot.

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.

Kinematics for modular wheeled mobile robots
Proceedings of 1993 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS '93), 2002The kinematics for modular wheeled mobile robots is presented. Basic theory of planar motion is used to derive inverse and forward kinematics. The inverse kinematics is inherently modular, whereas the information form of a least-squares estimator is required to completely modularize the forward kinematics. An implementation is described and results are

Image tracking for wheeled mobile robots
2008 27th Chinese Control Conference, 2008This paper is concerned with the control of a novel wheeled mobile robot using a FPGA-based proportional-plus-integral-plus-derivative theory and the image tracking technique. The structure of the manipulator contains a wheeled mobile robot, a multi-link robot, several motors, interface circuits, infrared sensors, and drivers.

Nonlinear Control Of Wheeled Mobile Robots
Proceedings of the IEEE/RSJ International Conference on Intelligent Robots and Systems, 2005Kinematic models for the description of wheeled mobile robots are introduced. The nonlinear controllabilityof these ciystems is proved. It is shown that the wheeled mobile robot cannot be asymptotically stabilized to a configuration (or position) by using time-invariant continuous feedback.
