This thing is not made for real wars!! But rather a RC toy fitted with guns etc for the use of CT ops, where the army can sneak it inside a house or inside enemy's area where a few terrorists are hiding behind a wall/bushes.
It has got 200 meter range only tells that Soldiers will always be very close to place where they will be operating it. In real wars enemy will most likely already know the presence of our troops(when they are so near) and they will be alert for such kind of thing, may be after a taking first few surprises bullets, news will spread fast among enemy.
Also I have serious doubt that if this can aim and fire even at 20% efficiency of a trained soldier, because the operator will be using a remote and will not have a situational awareness(from eye one can easily spot certain objects, but with a camera, one needs to find that thing on a tiny LCD screen)/quick reaction in aiming via hand would really not match the mechanical rotor. (the difference is like when you play a shooting computer game using a mouse you can get the cursor from one end to another in one mouse stroke, but while playing with gamepad, you need to press the up/down, right/left button and it goes a with a constant speed.)
Now coming to wheels,
@Kunal Biswas, I think for the vehicle of this size, wheels are better options. Because when it is so light, ground pressure will not really matter with six wheels, as the stress on the ground will not be high, and it should work well even in muddy/sandy situation(which they should have already tested). For such small vehicle using tracks means, most probably we have to go with the rubber tracks, as metal track at such small size will not really offer anything extra, except for reducing the efficiency, Small arm bullets against this size, will act similar to what an actual tank track will behave when hit by another tank gun. So if track gets broken by a bullet hit, vehicle will get disabled. Also there a good possibility of small objects such as stones or small wood sticks coming in between tracks and wheels and it will make the whole thing stuck. For wheels even the front 2 are hit or even if all are hit by bullets, as long as they keep rotating, it will move, because it is light and there is no risk of getting someone killed, meaning operator can call it back slowly(also I assume that the wheels at this size will use solid rubber like in toys, not tubes/tire combo).
Making a bigger machine with more capability will put it into a totally different category altogether, i. e. for the actual war, but for that range needs to be increase many folds with front and side armor protection from atleast 20-30mm gun and with a capable gun, and when it becomes heavy due above said things, then tracks too.
One thing that I would like for such small vehicles is to be able to raise height of the 7.62 mm gun when required via remote control(may be by 20cm). Because when operating there are good chances that small objects or ground pot holes or small up and down level for ground will obstruct its vision or may provide better cover, so having that capability will have many use, similar to how a soldier takes cover while lying down, but fires by raising his hand/head only.
