Opis:: The paper discusses mechanical properties of modern wheeled mobile robots including aspects of kinematics and dynamics. Relevant features of these robots and of used types of wheels are considered. Robots are categorized into six groups according to kinematic structures, which can be obtained using various types of wheels. For each group mechanical properties, which characterize the robots are discussed. Various variants of the robots within particular groups are described and some examples of existing solutions are given. Individual variants of the robots are compared and assessed taking into account the possessed features.

wheeled mobile robot
Opis:: Most dynamic models of wheeled mobile robots assume that the wheels undergo rolling without slipping, thus in general wheeled mobile robots are considered as nonholonomic systems. This paper deals with the problem of motion planning of mobile robots, whose nonholonomic constraints have been violated during the motion. The slipping phase is studied in details. A static model of interaction forces between wheels and ground is adopted by means of the singular perturbation approach [2]. A novel control theoretic framework for mobile robots subject to slipping is defined: both kinematics and dynamics of a mobile robot are modeled as a control system with outputs, the performance of a locally controllable system is nontrivial, the Jacobian of the mobile robot is defined in terms of the linear approximation to the system [36]. A novelty of the methodology consists in respecting of the analogy between the stationary and mobile robots and deriving performance characteristics from local controllability. In this paper we address the problem of motion planning by means of the Jacobian pseudo inverse algorithm. The effectiveness of the Jacobian pseudo inverse motion planning algorithm is demonstrated with reference to differential drive type robot (Pioneer 2DX) subject to slipping.

Data publikacji:: 2016

Tematy:: wheeled mobile robot
motion control
predictive control
model-based control
optimization
Opis:: The paper is concerned with the problem of tracking control of wheeled mobile robots (WMRs) using predictive control systems. Various kinematic structures of WMRs important from the point of view of motion control are discussed. A hierarchical approach to the problem of motion control of this kind of robots is presented. The problems of trajectory tracking and path following control of WMRs are briefly discussed. The methods of predictive control of WMRs are described in detail and the following aspects relevant to predictive control are considered: kinematic structures of robots, slip of wheels and its compensation, assumed constraints, methods of optimization of the objective function, problems of model nonlinearity, linearization and discretization, stability of the control system and use of the state observers.

Monte Carlo localization method
Opis:: The paper presents a method of localization of a mobile robot which relies on aggregation of data from several sensors. A review of the state of the art regarding methods of localization of ground mobile robots is presented. An overview of design of the four-wheeled mobile robot used for the research is given. The way of representation of robot environment in the form of maps is described. The localization algorithm which uses the Monte Carlo localization method is described. The simulation environment and results of simulation investigations are discussed. The measurement and control equipment of the robot is described and the obtained results of experimental investigations are presented. The obtained results of simulation and experimental investigations confirm the validity of the developed robot localization method. They are the foundation of further research, where additional sensors supporting the localization process could be used.
