    An eventual objective of mobile robotics research is to bestow the robot with high cerebral skill, of which navigation in an unfamiliar environment can be succeeded by using on‐line sensory information, which is essentially starved of humanoid intermediation. This research emphases on mechanical design of real mobile robot, its kinematic & dynamic model analysis and selection of AI technique based on perception, cognition, sensor fusion, path scheduling and analysis, which has to be implemented in robot for achieving integration of different preliminary robotic behaviors (e.g. obstacle avoidance, wall and edge following, escaping dead end and target seeking). Navigational paths as well as time taken during navigation by the mobile robot can be expressed as an optimization problem and thus can be analyzed and solved using AI techniques. The optimization of path as well as time taken is based on the kinematic stability and the intelligence of the robot controller. A set of linguistic fuzzy rules are developed to implement expert knowledge under various situations. Both of Mamdani and Takagi-Sugeno fuzzy model are employed in control algorithm for experimental purpose. Neural network has also been used to enhance and optimize the outcome of controller, e.g. by introducing a learning ability. The cohesive framework combining both fuzzy inference system and neural network enabled mobile robot to generate reasonable trajectories towards the target. An authenticity checking has been done by performing simulation as well as experimental results which showed that the mobile robot is capable of avoiding stationary obstacles, escaping traps, and reaching the goal efficiently

    Autonomous underwater robots have become indispensable marine tools to perform various tedious and risky oceanic tasks of military, scientific, civil as well as commercial purposes. To execute hazardous naval tasks successfully, underwater robot needs an intelligent controller to manoeuver from one point to another within unknown or partially known three-dimensional environment. This dissertation has proposed and implemented various AI based control strategies for underwater robot navigation. Adaptive versions of neuro-fuzzy network and several stochastic evolutionary algorithms have been employed here to avoid obstacles or to escape from dead end situations while tracing near optimal path from initial point to destination of an impulsive underwater scenario. A proper balance between path optimization and collision avoidance has been considered as major aspects for evaluating performances of proposed navigational strategies of underwater robot. Online sensory information about position and orientation of both target and nearest obstacles with respect to the robot’s current position have been considered as inputs for path planners. To validate the feasibility of proposed control algorithms, numerous simulations have been executed within MATLAB based simulation environment where obstacles of different shapes and sizes are distributed in a chaotic manner. Simulation results have been verified by performing real time experiments of robot in underwater environment. Comparisons with other available underwater navigation approaches have also been accomplished for authentication purpose. Extensive simulation and experimental studies have ensured the obstacle avoidance and path optimization abilities of proposed AI based navigational strategies during motion of underwater robot. Moreover, a comparative study has been performed on navigational performances of proposed path planning approaches regarding path length and travel time to find out most efficient technique for navigation within an impulsive underwater environment

    21st century is the era of competition with full of stress having more speed and accuracy are the prime demand to fulfill their need. The needs of the human being are infinite but the availability is less to fulfill the growing needs. So man is trying to utilize his time in fulfillment of such needs without thinking about his health. He is changing his lifestyle, diet pattern and behavioral pattern and inviting many lifestyle disorders like Amlapitta. Ayurvedic literature mentions about diseases Amlapitta mainly caused because of Ahitakara Ahara, Vihara and Manasika Bhava. So avoiding such Nidana can prevent and control the disease. So in this present study importance has been given for Aharaja and Viharaja Nidana in the manifestation of Urdwaga Amlapitta. As no considerable works were done w.s.r to Nidana, the study was taken up entitled “An Observational Study on Urdwaga Amlapitta Nidana w.s.r to Diet and Lifestyle”

    Role of Rasayana in Geriatric Care - A Review

    Get PDF
    The growth of any country or society depends on the number of youth dwelling in that country but according to recent statistical data we soon will have older people more than children and more people at extreme old age than ever before. The number of people aged 65 or older is projected to grow from an estimated 524 million in 2010 to nearly 1.5 billion in 2050. Geriatrics (Jarachikitsa) is the branch of medicine dealing exclusively with the problems of aging and the diseases of elderly. The term Rasayana (rejuvination) refers to nourishment or nutrition. Rasayana therapy act essentially on nutrition dynamics and rejuvenate the body on both physical and mental levels. The problems of health due to modernization can be solved by increasing resistance against diseases and psychological improvement by implementing Rasayana therapy. Aging (Jara) is one among the Swabhavika Vyadhis. Jara Chikitsa is one among the Astanga of Ayurveda which is specifically dedicated for geriatric care. As per estimation, India currently has around 75 million persons over 65 years. By proper administration of Rasayana therapy as preventive tool one can delay Jara Janita Vyadhis to occur. This paper highlights the role of Rasayana in geriatric care

    Critical analysis of Nitya Sevaniya Ahara Dravya’s - Balanced diet in Ayurveda

    Get PDF
    Acharya Charaka describe that the whole world runs towards food, as complexion, happiness, pleasant voice, life, talent, health and satisfaction, maintenance of body, body strength and even intellectual capacities of the individual depends on food. Since from Vedic period they gave importance to the food. In Upanishad food is considered as Brahma. Food is a substance consumed other than water and drugs for maintenance of the health, well-being and vitality of the individual. Present paper highlights the importance of Ayurvedic nutrition in the form of Nitya Sevaniya Ahara Dravya and critical analyses on the importance of it in day today life
