How to make a 5 kg war bot for Robo sumo( part 1) .....

Image
 If you are want to make a 5 kg sumo robot for Robo war then you must have to follow some theory. I am telling you the right theory behind those bot's, and with out this theory you are not able to understand that how much power and torque will required to operate your bot. 1. Circumferential Velocity Calculation: If you are think that at first you chose the motor and then you will find wheels for your Bot, then my friend your idea is totally wrong. At first chose your  Bot's wheel then calculate the circumferential velocity. Now, usually in most of cases we are using 2 or 3 inch wheel for our 5 kg war bot. Consider 3 inch wheel and we will get the Circumference is 0.235 metre. Remember this one you have to convert those units in SI. And suppose consider your motor's RPM is 300. Now, Circumferential Velocity of your bot is Vs= (Ï€ * D *N)/60 ;        (Ï€ * D) is  Circumference of wheel                                                                               =(0.235*300)/

GHATAK new update

Image
3,000 crore rupees is sanctioned by the government to develop the India's most secret project AURA.  That would be designed and developed indigenously, and the privet sector companies played a big role in this project. AURA UCAV or GHATAK is an autonomous unmanned  combat aerial vehicle, that can able to firing weapons. The project is being designed by Aeronoutical Development Agency (ADA) and being developed by DRDO. In 2007 when Russia, America, France and England walk over the same path to develop a unmanned combat aircraft,  DRDO proposed  the same project in front of us and that's the starting of the journey of AURA project. GHATAK would be capable for realizing missiles, Bombos and precision-guided missiles. It can able to carry two or more guided strike weapons with on-board sensors for tergeting and weapon guidance at medium altitude. The flight control system and data link system of UCAV is being developed by ADA and DEAL(Defence Electronics Application Laborator

FGFA:India's Fifth Generation Fighter Aircraft

Image
The FGFA or PMP (Perspective Multi-role Fighter) project will jointly developed by Sukhoi and HAL, the designed is based on the Russian Sukhoi Su-57 equipped for the Indian Air force. FGFA is a stealth Multirole and Superiority fighter, which is directly competitive with F-22 Raptor and Erofighter Typhoon. The Indian Su-57 or FGFA comes with 43 improvements over Su-57,equipped with Advance sensors, Networking and Combat Avionics.The Indian version would be also a two-seater with pilot and weapon system operator. It's assumed that the specifications like length, Wingspan, Height, are same as the Su-57. The maximum weight carrying capacity up to 35,000 kg. This Fighter will equipped with 2 AL-41F1 afterburning turbojet Engine, Which will able to generates 93.1 KN thrust each and 147 KN thrust with afterburner. That massive thrust helps to reach maximum speed of 2,120 km/h or Mach 2. The operational range of this fighter would be 3,500 km at subsonic speed and 1,500 km at supers

Project-18 It's not just a Destroyer

Compare The CO2 Emission of Hydrogen Fuel cell cars and Conventional Gasoline Engine cars

Image
 In order to reduce emitted greenhouse gases slowly we should move on to the Electric vehicles (EV) and the Hydrogen Fuel Cell cars. That’s why many privet vehicle manufacturers are manufacturing different types of EV’s and Hydrogen fuel Cell cars. There is no doubt that the Hydrogen fuel is the future fuel. But the other most trending question in front of us is , Are Hydrogen Fuel Cell cars Eco-Friendly today in India? No, Hydrogen Fuel Cell cars are not so Eco-Friendly today In our Country. Because most of the   electricity is produced by fossil fuels simply from coal. And the coal mining is also not environment friendly. For better Understanding we should compare the CO2 Emission of  both Hydrogen and Gasoline fuels in different phases. Before comparison we should knowing about the grid power production in India.  The maximum energy of grid is produced in India from burning  of coal and few from natural gas is around 57%. Now if the power station with an efficiency of 34%

Other details TATA's HBX is based on the new ALFA platform, that means more effective legroom, comfort and space.The relatively flat floor should give the rear-centre passenger a

REALITY OF ELECTRIC VEHICLES

Image
Today's most trending topic ,Is Electric Vehicles are more Eco-friendly choice in India? India emits around 3 Giga tonnes of CO 2  and other greenhouse gases per year globally. And t he maximum energy of grid is produced from burning the coal and few from natural gas is around 57% in India. Now if the power station with an efficiency of 34% burns coal, it emits 1.0 kg CO 2  for generating of one kwh of electricity.( That means   1kwh electricity = 1 kg of CO 2 ).  Nearly 25% of this emission occurs due to each and every types of road transport vehicles. Now in order to reduce emitted greenhouse gases slowly we should move on to the Electric vehicles ( EV ). That’s why many privet vehicle manufacturers are manufacturing different types of EV’s .  Many of peoples are appreciated that  all EV ’s are environment friendly then the conventional IC engine vehicles ( ICV ) . But is it true? No,  EV's are not recently purchasable Eco-friendly, It's takes some time to make it Eco
