1. IEEE CS 70 th Anniversary Student Challenge Project Proposal entitled “ROBOT CONTROLLING WEATHER ” Submitted By: S.SEETHALAKSHMI E.VANISRI M.PRIYADHARSHINI R.SANGEETHA From IFET College of Engineering, Villupuram, Tamil Nadu, INDIA

2. OBJECTIVE The main objective is to provide artificial rain to very dry areas. To promote cultivation of crops in drought-stricken areas. To promote water availability even in desert areas.

3. INTRODUCTION This method uses cloud seeding technique. In this method the atmospheric temperature is sensed with temperature sensors. Based on the sensor output,cloud seeding is carried out.

4. EARLIER APPROACH Research on the subject has been ongoing for more than a century. But it's still not clear how well it actually works in reality - a cloud might produce rain after being seeded. But it's hard to know if that cloud would have just produced rain anyway.

5. Cont.. The promise of weather control has lead to a lot of cash being pumped into various cloud seeding schemes. The most famous attempt was probably in 2008 during the Summer Olympics, when China attempted to use cloud seeding. To ensure that clouds dropped their rain before passing over the opening and closing ceremonies.

6. LATEST RESEARCH Engineers and meteorologists from Nevada have joined forces to create the first autonomous cloud seeding platform. Using drones to control the weather. They used a DAx8 drone, which can carry heavier payloads thanks to its eight rotors, and successfully completed flare tests in late January 2016.

8. PROPOSED IDEA In this proposal we are going to sense the atmospheric temperature using sensors. If the result of sensor is not favorable then cloud seeding comes to exist. The robot which is flying in the cloud will perform cloud seeding.

9. Cont.. As a result of cloud seeding we will get rainfall. Using this we can bring rainfall even to desert areas. We can operate the robot as per our requirements.

10. COMPONENTS USED A normal flying robot. Temperature sensor. Robotic arm carrying cloud seed substances.

11. TECHNIQUE USED Cloud seeding Temperature sensing

12. CLOUD SEEDING Cloud seeding is a technique where small particles are dropped into a cloud. Cloud seeding From an aircraft or rocket to alter the microphysical processes going on inside and make it rain (or snow). Cloud seeding is no longer considered a fringe science, and is considered a mainstream tool to improve rain precipitation and snow.fringe science

13. CHEMICALS USED The most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice (solid carbon dioxide). chemicalssilver iodidepotassium iodidedry ice Liquid propane, which expands into a gas, has also been used. This can produce ice crystals at higher temperatures than silver iodide. Liquid propane After promising research, the use of hygroscopic materials, such as table salt, is becoming more popular.hygroscopic

15. TEMPERATURE SENSORS Temperature Sensors measure the amount of heat energy or even coldness that is generated by an object or system. Allowing us to “sense” or detect any physical change to that temperature producing either an analogue or digital output. These sensors are used to detect the change in the climate. It produces the response based on the atmospheric temperature change.

16. DESIGN In addition to already designed techniques we are using an additional arm to it to hold the cloud seed particles. It also possess a inbuilt temperature sensor which senses the temperature of the atmosphere. When the temperature exceeds the limit the robot will perform cloud seeding.

18. ADVANTAGES The major advantage of this method is to provide rainfall to drought –stricken areas. To enrich the water resources of our nation. To enrich our land productivity and bring agricultural development.

19. DISADVANTAGES Cloud seeding does involve the use of chemicals into the air. Because of it can potentially harm the environment, especially plants and animals. The high cost of doing it is not even believed to be justifying its effectiveness.

20. FUTURE SCOPE Though there are many researches going on there is no confined method for this technique. We hope that surely in future the entire world will come into the hands of robot including weather.
