 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                    ...

ARYUN MK-1A The killer machine is Back

The Indian Army focus on the  indigenously developed  ARJUN  MK-1A main Battle Tank ,which is the upgraded version of Arjun MK-1 .

Variable ammunition were incorporated to enhance the death of the enemy tank in the battle field. On the other hand conventional Fin Stabilised Armour Piercing Discarding Sabot (FSAPDS) and High Explosive Squash Head(HESH) ammunition , Thermo Baric (TB) and Penetration Cum Blast (PCB) ammunition have been improved And a Remote Controlled Weapon Station That provides the capability to the loader of engaging ground targets and aerial targets from the protective envelop of the tank Armour. 



The Explosive Reactive Armour (ERA) panels are provided for effective protection against the Armour Piercing rounds ,anti-tank grenades and missiles . Those panes have been mounted on the front arc of the hull and turret. 
Arjun MK-1A also protected against chemical attacks.  A special type of chemical sensor is equipped to detect the harm full toxic chemicals in the atmosphere .

The Engine of the Arjun MK-1A also being upgraded  1400 HP to 1500 HP and the Tanks weight is uniformly distributed that makes it more mobile. The manual transmission is upgraded to Automatic Transmission Syatem. An Advanced Land Navigation Syastem is also be equipped, that helps the Tank to understand where needs to go in the absence of any signage in the war theatre. And An uncooled Night Vision camera for driver has been provided for the better controling the tank in night.
