چکیده

The problem of localization is well known in mobile robotics. A solution is to use a model-based technique such as a kalman filter with multi sensor data fusion. For a car-like mobile robot, the nonlinear dynamic model is suitable for robot movement representation. This work presents the discrete extended kalman filter including a nonlinear dynamic model for the mobile robot localization. As inputs for the kalman filtering, gyroscope and compass sensors provide the relative and absolute yaw angles. The experiments are performed on several path types and the averages of the final position errors and the final heading errors are proposed.

Solving Path Following Problem for Car-Like Robot in the Presence of Sliding Effect via LMI Formulation

One of the main problems of car-like robot is robust path following in the presence of sliding effect. To tackle this problem, a robust mix H2/H∞ static state feedback control method is selected. This method is the well-known linear robust controller which is robust against external disturbance as well as model uncertainty. In this paper, the path following problem is formulated as linear matri...

Robust Sliding Mode Controller for Trajectory Tracking and Attitude Control of a Nonholonomic Spherical Mobile Robot

Based on dynamic modeling, robust trajectory tracking control of attitude and position of a spherical mobile robot is proposed. In this paper, the spherical robot is composed of a spherical shell and three independent rotors which act as the inner driver mechanism. Owing to rolling without slipping assumption, the robot is subjected to two nonholonomic constraints. The state space representatio...

Dynamic Modeling and Construction of a New Two-Wheeled Mobile Manipulator: Self-balancing and Climbing

Designing the self-balancing two-wheeled mobile robots and reducing undesired vibrations are of great importance. For this purpose, the majority of researches are focused on application of relatively complex control approaches without improving the robot structure. Therefore, in this paper we introduce a new two-wheeled mobile robot which, despite its relative simple structure, fulfills the req...
