Multicopter are slowly finding its way into various industrial sector applications including security, oil & gas, public health, etc. Unmanned Aerial Vehicles provides faster and reliable solutions for many real time challenges. Spraying sanitizers using drone is one such solution which is effectively implemented during COVID-19 pandemic situation. Hexacopter is designed to carry up to 2 litres of sanitizer in its reservoir and the sanitizer spray system is designed to dispense the liquid as droplets at a constant flow rate. Hexacopter is made of carbon fibre and equipped with Pixhawk autonomous module as flight controller. The UAV can be operated in both manual and autonomous modes to increase the ease of operation for indoors as well as in outdoors sanitization process.
Road transport plays an important role in India’s economy. It enables the country’s transportation sector to contribute 6.1% towards India’s GDP. The road network in our country is considered as a critical factor to the country’s development, social integration and security needs of the country. The Government of India has promoted foreign investments in highway projects to bring out high standards and quality. India’s road network carries over 65% of freight and 85% passenger traffic. The traffic volume carried by the national highways almost exceeds the designed traffic volume, and hence the desired speed cannot be achieved. Thus, widening of highways becomes necessary. The population growth is also to be considered and hence provision for future widening is to be provided. Our paper deal with the geometric design for widening of NH-9 is carried out using MX-Bentley software as per IRC specifications. This design includes horizontal and vertical profiling throughout the stretch of the road, according to the existing topographic data. The radius of the curve has been increased to make a smooth curve. Also, the vertical profile has been designed based on the allowable gradient and sight distances. From this, accommodation of more traffic volume and increment of design speed seems to be possible.
Spy robot is a Wi-Fi controlled robot. A camera mounted on the robot sends real time video signals on to the user side, which can be seen on a display. Robot movements can be monitored looking at the display. Saving human life and providing security to the same both are two different aspects, but both are essential and instead mandatory. A robot is a sort of human replacement which is controlled by human itself. Areas where human cannot be sent, or life of human is endangered; robots can be used in such cases. In various military applications and for security purposes our project can also provide live streaming of various on goings which the robot witness at the site.The more advanced features used in this spy robot is to climb the vertical and inclined surfaces, obstacle detector, night vision camera to detect the objects in darkness. The goal of spy robot is to search interesting stuff from where people are not able to reach. This project has three subsystems: Hardware, Software & Mechanical. The project is comprised of basically three modules, which handles all the basic Functionalities of the robot.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
