 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                    ...

Electric Car was invented over 135 years ago

-
yes, that's true although the Combustion Engine cars is always the king of the roads but the Electric car was on the road first.


 In 1884 ,Thomas Parker built world's first practical Electric Car over 135 years ago.Thomas Parker was born on December 22,1843 in Coalbrookdale,Shropshire.In 1857 he made a small steam engine, and in 1859 he made a violin.Then he invented world's first Eco-friendly car.The interesting think about this car is, each and every component like battery ,motors was design by Parker.




 Thomas Parker was not the first person who create a vehicle that could run on electric ,but Parker's electric car was more practical one. It was the first electric vehicle that had the potential to be mass produced.The world's first Eco-friendly car was invented before 100 years,  the word Eco-friendly was first in front of us. In 1883 Parker's company at first design,build and install dynamos. After invented the car ,Parker developed several models of electric car.One of the main drawback with this car is the speed limit,this car could be able to run at only 2 miles per hours speed . The most biggest challenge over Parker that he had a limited battery technology.That's why Parker's electric car was not successful over the Combustion Engine cars.

REALITY OF ELECTRIC VEHICLES

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...
