Motion planning and control of a Nomad 200 mobile robot are studied in this thesis. The objective is to develop a motion planning and control algorithm that is able to move the robot from an initial configuration (position and orientation) to a goal configuration in a typical laboratory environment. The robot must be able to avoid unknown static (e.g., walls and tables) and dynamic (e.g., people) obstacles. Dubin"s algorithm finds the shortest path connecting two configurations in an obstacle-free environment, but it is not able to avoid obstacles present in the environment. The potential field algorithm is effective in avoiding unknown obstacles, but it has the local minimum problem and does not consider the orientation of a mobile robot. A modified potential field algorithm is first developed. The algorithm overcomes local minima in a typical laboratory environment. The modified potential field algorithm is then combined with Dubin"s algorithm to incorporate orientation into motion planning. The combined algorithm is able to avoid static and dynamic obstacles and achieve position and orientation requirements. Simulation and physical experiment results are presented to demonstrate the effectiveness of the algorithm.

navigation of a mobile robot in a completely or partially unknown environment. A neuro-fuzzy controller based mobile robot navigation presented by Kim and Trivedi . In this study they have implemented neural integrated fuzzy controller to control the mobile robot motion . Offers a theoretical and practical guide to the communication and navigation of autonomous mobile robots and multi-robot systems This book covers the methods and algorithms for the navigation, motion planning, and control of mobile robots acting individually and in groups. It addresses methods of positioning in global and local coordinates systems, off-line and on-line path-planning.

This environment may involve any number of obstacles of arbitrary shape and size; some of them are allowed to move. We describe our approach to solving the motion-planning problem in mobile robot control Cited by: The objective in motion planning is to compute a motion tra-jectory from an initial state to a goal region that avoids col-lisions with obstacles. In addition, motion planning needs to take into account the underlying robot dynamics in order to plan dynamically-feasible motions that the robot .

Especially, in dynamic environments, for two-wheeled mobile robot proposed a motion planning strategy, where the translational speed of the robot is defined by considering the distance between robot and obstacles, and the influence range of obstacles.
That is, the translational speed is decided without considering the orientation of the by: The motion planning problem of a mobile robot in a dynamic environment is to plan and control the robot motion from an initial position to track a moving target in a desired manner while avoiding moving obstacles.

Robot motion planning in dynamic environments has re-cently received substantial attention due to the DARPA Urban Challenge  and growing interest in service and assistive robots (e.g., , ).
In urban environments, trafﬁc rules deﬁne the expected behaviors of the dynamic. Introduction. Robot motion planning in dynamic environments is one of the areas of research in computer science and computational geometry.
The fundamental problem of motion planning is obtaining a collision-free path from start to goal for a robot that moves in a static and totally known environment Cited by: the robot starts its motion. On the other hand, local path planning means the environment is completely unknown to the mobile robot; in other words, the algorithm is capable of developing a new path to reach at the destination point.
We discuss path planning methodologies for autonomous mobile File Size: KB. The potential field method is widely used for autonomous mobile robot path planning due to its elegant mathematical analysis and simplicity. However, most researches have been focused on solving the motion planning problem in a stationary environment where both targets and obstacles are stationary.
This paper proposes a new potential field method for motion planning of mobile Cited by: The book provides a host of experimental results, a conceptual overview of systemic and software mobile robot control architectures, and a tour of the use of wheeled mobile robots and manipulators.

In order to implement ERRT we need an extend operator, a dis-tance function between robot states, a distribution for generating ran-dom states in the environment.
This thesis is concerned with robot motion planning in dynamic, cluttered, and uncertain environ-ments. Successful and eﬃcient robot operation in such environments requires reasoning about the future system evolution and the uncertainty associated with obstacles and moving agents in the environment.
