Modeling of slip for wheeled mobile robots [PDF]

open access: yesIEEE Transactions on Robotics and Automation, 1995
Wheeled mobile robots (WMRs) are known to be non-holonomic systems, and most dynamic models of WMRs assume that the wheels undergo rolling without slipping. This paper deals with the problem of modeling and simulation of motion of a WMR when the conditions for rolling are not satisfied at the wheels.

Energy-Time optimal control of wheeled mobile robots

open access: yesJournal of the Franklin Institute, 2022
This paper focuses on the energy-time optimal control of wheeled mobile robots undergoing point-to-point transitions in an obstacles free space. Two interchangeable models are used to arrive at the necessary conditions for optimality. The first formulation exploits the Hamiltonian, while the second formulation considers the first variation of the ...

Obstacle Avoidance by Means of an Operant Conditioning Model [PDF]

open access: yes, 1995
This paper describes the application of a model of operant conditioning to the problem of obstacle avoidance with a wheeled mobile robot. The main characteristic of the applied model is that the robot learns to avoid obstacles through a learning-by-doing

Dynamics of a four‐wheeled mobile robot with Mecanum wheels [PDF]

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2019
AbstractThe paper deals with the dynamics of a mobile robot with four Mecanum wheels. For such a system the kinematical rolling conditions lead to non‐holonomic constraints. From the framework of non‐holonomic mechanics Chaplygin's equation is used to obtain the exact equation of motion for the robot.

Exponential ε-tracking and ε-stabilization of second-order nonholonomic SE(2) vehicles using dynamic state feedback [PDF]

open access: yes, 2002
In this paper, we address the problem of ε-tracking and ε-stabilization for a class of SE(2) vehicles with second-order nonholonomic constraints. We introduce a class of transformations called near-identity diffeomorphism that allow dynamic partial ...
