Variable Wheelbase Control of Wheeled Mobile Robots With Worm-Inspired Creeping Gait Strategy
IEEE Transactions on roboticsWheeled mobile robots (WMRs) with variable wheelbases are capable of traveling on deformable terrains and handling complex detection tasks. While the variable wheelbase length of WMR allows it to interact with the terrains adaptively, enhancing its ...

Journal of the Franklin Institute, 2020
This article tackles the trajectory tracking problem for a non-holonomic wheeled mobile robot (WMR) with non-random and random disturbances. A nonlinear disturbance observer with extended Kalman filter (NDEKF) is designed to observe the velocity and the ...

Fixed-Time Leader-Following Consensus for Multiple Wheeled Mobile Robots
IEEE Transactions on Cybernetics, 2019This article deals with the problem of leader-following consensus for multiple wheeled mobile robots. Under a directed graph, a distributed observer is proposed for each follower to estimate the leader state in a fixed time.

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.
