GPS Based Autonomous Vehicle Navigation and Control System
The main aim of the paper is the development of an overall routing system which accepts input from common users via a simple android application and as a result directs the nearest vacant Cab towards the passenger. In this project two algorithms for the implementation of our project have been developed. The first algorithm is an autonomous route calculation algorithm in which a PC is used to calculate coordinates at each road intersection between any two input coordinates. The PC takes input coordinates from user and transmits the output coordinates to the cab. The 2nd algorithm is a control algorithm that navigates our prototype robots. It does so by using Haversine heading and distance formulae. The code gets it desired set point in the form of input coordinates and compares it to the robots current heading to compute an error signal. Based on this signal the robot’s heading is changed to maneuver it within the robot boundaries. This type of system has a variety of applications and can be used for other purposes such as guiding a completely autonomous robot to distressed areas.

Milk products monitoring system with arm processor for early detection of microbial activity
Smart City initiative is an attempt to identify the technologies that can solve problems which cities must confront, such as poor air quality and health related issues, and hence create a network of partner cities to share the ideas for future progress. In this work an issue which is to facilitate smarter cities through world sensing is discussed. Food safety in rural and urban areas is a very important topic, as it closely affects the health of citizens. Recent studies highlight that raw milk contain pathogenic organisms which could result in illness if consumed which can increase the incidence of diseases and deteriorate the quality of life. Hence, it is necessary to develop tools for real-time and smart sensing for quality monitoring, so and to make appropriate and timely decision. In this paper, we present uSense, a low-cost cooperative monitoring tool that allows one to know, in real-time, the concentrations of gases in raw milk. As the raw milk is stored for many days the growth of bacteria will be more which results in undesirable smell, taste and toxic substances. Hence there is need for monitoring system to detect and identify the spoilage of milk and produce a healthy product. Therefore this work helps in early detection of toxic substances in milk to avoid complications in the initial phase for a good final product. The proposed prototype is an ARM based monitoring unit which monitors the unwanted ingredients present in the tested milk with the help of TGC gas sensors. The concentration of volatile organic compounds (VOC) present in the head space of milk is degraded drastically and contaminated when it is found with bacteria, Senescent, photo oxidation, and provident metals such as copper, Iron and nickel. The raw milk obtained has some bacteria which do not have ill effect but as it is refrigerated and stored for many days there will be rapid transformation of bacteria which yields in to spoilage of milk. So there should be appropriate measures to handle the raw milk in order to avoid degradable effects.
