Planning a Mobile Robot in Static and Dynamic Environments

Chapter.1 Introduction 1.1 Introduction:- In this Research develops and implements a Genetic Algorithm based approach with a Grid search method for path planning for a mobile robot in Static and dynamic environments. The approach uses the search of the static and dynamic obstacles as search space. Using the Grid search method, it searches an initial feasible path for the robot in the environment. In an environment with obstacles, a mobile robot must be able to generate collision free paths to move from an initial location to a final location, and in order to truly show a level of intelligence these paths must be optimized under some criteria that is most important to the robot, the terrain and the problem given. The approach applies the Genetic algorithm to find the optimal path for the robot. Mobile robot path planning is a research area of Artificial intelligence and Robotics. Researcher from all over the world have carried out a of studies on robot path planning by using the artificial neural Network , Neuro fuzzy Method, potential field method, ant colony algorithm, genetic algorithm and so on. Artificial potential field method is suitable for underlying real-time path control with the lack of global information. But it has the problem of local path planning. Neural network method has good ability optimization of problem.

Humanoid design has a difficulty, which is the kinematic interpretation of human joints and development of mechanisms in order to entertain human motion. The work mainly focuses on the development of kinematic description of the shoulder-elbow complex. There is a quantified coupling, which exists between the shoulder movement and the elbow joint orientation. A mechanism is introducedRead MoreVaining Comparison And Opportunity9989 Words   |  40 Pagesstudies have exploited the mobility of sensors to improve the quality of coverage and con nectivity. Authors in [74] presented a relative neighborhood graph based connectivity preservation scheme. By assuming that the initial system is connected, the mobile sensor nodes move in the calculated direction and distance (limited by the communication range of the sensor) to approach the required system coverage. During the movement, the connectivity between each pair of connected nodes is preserved. SimultaneouslyRead MoreWalmart Case Study5373 Words   |  22 Pagesand Union problem, clouded this fact.

The Two Waves of Globalization Industrial Revelution and...

The main idea of this article is that there were two major waves of globalization, both of which were â€Å"superficially similar, but fundamentally different.† The first wave occurred during 1870-1914 and the second from 1960 to present. The superficial similarities between the two include the aggregate trade-to-GDP ratio and capital flow-to-GDP ratios in addition to the importance of reductions in technical and policy barriers to international trade. The fundamental differences, on the other hand, are the impact reductions had on trade and the economic beliefs and initial conditions of the two periods. The first wave of globalization was driven by the Industrial Revolution. It transformed the British economy by improving transportation,†¦show more content†¦Whereas the first wave was a result of industrialization, the second wave came from de-industrialization. When the second wave began, the world was already distinctly divided between rich industrial nations and p oor primary producer nations. Income divergence became wide in the world while convergence only occurred among the wealthy nations. This was due to the fact that world trade became dominated by intra-industry trade by rich countries with similar factor endowments, such as labor and capital. Hence, the rich kept becoming richer and the poor stayed poor. By this beginning of this period, transport costs had already decreased significantly. This coupled with a growth in international financial markets would cause one to believe that capital mobility levels were high. However, studies show that this was not the case and that levels are actually not as high today as they were during the first wave. In contrast to the long-term foreign direct investments prevalent during the 19th century, the 20th century is more focused on the quick and continuous movement of highly liquid assets. Today, the biggest concern is exchange rate management and the world trading system is now viewed as an esse ntial public good. Presently, strong institutions uphold the system and protectionist policies are almost obsolete (with the exceptions of some counties like China and Russia). Institutions like the

Critical Review My Place Free Essays

CRITICAL REVIEW: MY PLACE, SALLY MORGAN Sally Morgan’s My Place, published in 1987, is an autobiography about finding her Aboriginal roots and her identity with the focus on the lives of three generations of Australian Aborigines. Sally’s family never talked about their past and she was brought up thinking she was Indian. But she always felt different than her friends, their way of living was not the same, so her curiosity led her to realizing that she is Aborigine. We will write a custom essay sample on Critical Review My Place or any similar topic only for you Order Now And then her quest for knowledge of her past begins. My Place is actually a novel about woman’s search to find herself and her place in Australian society. The main themes are discrimination, racism and Aboriginal culture. They are presented through two different versions of autobiographical writing. One is Sally’s first person narration, which is more Western autobiographical and it focuses more on her individual quest to find her identity. The other focuses on the Aboriginal life and more on the community and family life of Aborigines. The novel has 32 chapters, which are divided into four parts: Sally’s narration about her early life, education, family relationship, her perception of herself and her self-discovery; Arthur Corunna’s story, he is a brother of Sally’s grandmother; her mother’s Glady’s story and her grandmother Daisy’s story. Their stories focus on their life when they lived in Aboriginal society. The whole book is a combination of narration, dialogues, descriptions, stories within stories, anecdotes, and personal reminiscences from various characters and also humour. All that provides balance and harmony to the book. The book is easy to read, the language is quite simple, descriptions of the nature are really specific and with the use of metaphors, symbolism and personification, the reader gets a vivid picture of the place that is described. However the first part, where Sally describes her childhood is a little bit boring, because there are mostly descriptions and details about things not relevant to the theme of the book. But when she starts to investigate her family roots with her constant attempt to get some answers from her mother and grandmother, the book becomes more interesting. The parts where her family talks about their life are very emotional, the reader gets an insight into their hard life as being black in the â€Å"white world†. Before Sally’s book, not much was known about the Aboriginal life. She writes about the contact of two different cultures, Aboriginal and Western, so we get in touch with their history, their habits, way of thinking, historical background, injustice and struggles they had to fight. Other people always treated them as something less and because all the bad things that happened to them, they decided not to speak about it, they were forced to be silent. There are still a lot of secrets, that are not revealed in the book, because they are too afraid to speak about them, but we get to know some important information about their past from the people who wrote history on their own skin. So this is a really important book for Australian and Aboriginal culture, because it opens some important questions about racism and discrimination.
