 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= (π * D *N)/60 ;        (π * D) is  Circumference of wheel                    ...

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 so...
