Navigation of Automatic Vehicle using AI Techniques

In the field of mobile robot navigation have been studied as important task for the new generation of mobile robot i.e. Corobot. For this mobile robot navigation has been viewed for unknown environment. We consider the 4-wheeled vehicle (Corobot) for Path Planning, an autonomous robot and an obstacle and collision avoidance to be used in sensor based robot. We propose that the predefined distance from the robot to target and make the robot follow the target at this distance and improve the trajectory tracking characteristics. The robot will then navigate among these obstacles without hitting them and reach the specified goal point. For these goal achieving we use different techniques radial basis function and back-propagation algorithm under the study of neural network. In this Corobot a robotic arm are assembled and the kinematic analyses of Corobot arm and help of Phidget Control Panel a wheeled to be moved in both forward and reverse direction by 2-motor controller have to be done. Under kinematic analysis propose the relationships between the positions and orientation of the links of a manipulator. In these studies an artificial techniques and their control strategy are shown with potential applications in the fields of industry, security, defense, investigation, and others. Here finally, the simulation result using the webot neural network has been done and this result is compared with experimental data for different training pattern

Is pregabalin better than gabapentin in treatment of neuropathic pain? An observation-based study at tertiary care centre of North India

Background: The present study was undertaken to assess the efficacy of pregabalin and gabapentin in treatment of neuropathic pain at a government tertiary care hospital of Uttar Pradesh, India. Due to indiscriminate use of drugs for treatment of neuropathic pain, selection of an effective drug is need of hour.Methods: Out of 130 patients, 62 patients were given pregabalin and 68 were given gabapentin. Douleur Neuropathique 4 questionnaire (DN4) which was used to diagnose patients of neuropathic pain. Efficacy of drug was based on their capability to decrease neuropathic pain at regular intervals.Results: On comparing the efficacy of drugs by their ability to decrease neuropathic pain, there was a significant difference when comparing pregabalin and gabapentin, pregabalin being statistically significant than gabapentin.Conclusions: On the basis present study efficacy of pregabalin 300 mg once daily brought better improvement of symptoms and sign than that of gabapentin 600 mg administered once daily dose. So pregabalin is a better drug than gabapentin
