BB-8

[gag09]

Just curious has anyone made a stock version of BB-8 from starwars in KSP?

I expected more...

So did I.

Kinda hard to do a stock rolling ball with a head on top
Heres his grandpa though

Ayyyy lmao

I think I know how to make this. It will almost certainly not work but I will give it a go.

Not stock, but I've just made a working prototype with infernal robotics to drive it.  Aside from IR the main parts are stock, just tweak-scaled to be smaller.

Amazing. I am at a loss for words.

A very basic version

Alright. I tried to make a BB-8 droid yesterday. After a lot of unsuccessful testing, I present to you the best result I ended up achieving:

This BB-8 can move (it has hidden wheels on the bottom) but it doesn't like inclines or braking too quickly. Nevertheless, it's completely stock and I think it's a suitable representation of the droid.

If yeh like it, I could probably deliver a .craft file (though not right now; I can't access KSP at the moment).

fun here's a BB8 full stock (which actually uses it's ball for moving :p)

here's a small gif of it (low quality) : http://imgur.com/rW8Tgyw

Operations :

engage SAS, then stage once to separate the 'head' from the ball (you'll know on which part you'll be when switching vessel, the 'head' as nothing in staging, while the 'ball' has the decoupler and the fairing in it's list )

switch to the ball if necessary, disable the SAS on the ball, and trim roll to the maximum right (alt+Q by default)

switch back to the 'head', and you can adjust it's course as necessary (W / S controls the head's angle around the white part, Q / E allows you to go left / right, A / D allows you to tilt on the side

for stopping, switch back to the ball, and kill the trim (alt+X by default), and BB8 will stop

 

roughly 5 m/s of speed on flat surface, and can climb up KSC's slopes at around 4m/s

(as an added bonus, the head tend to tilt a bit forward on it's own when it's moving :p)

Not bad dude! I can see how to make one that goes forward however I am testing one that can move in all directions. I am not sure it will work though.

mmmh - given that current wheels don't transfer forces to the objects they are rolling on, one possible stock way would be by using a cage around a 'sphere' of reaction wheels. (with the RW sphere attached to the rolling part of the body) the head would be attached to the cage (with translation so it's outside the ball body), with additionnal counterweights and RWs fixed to the cage to maintain the head upright. though, in this config, you'll need to switch to the ball each time you want to roll in another direction

The head will always be attached to the central part. My test craft is different to the one you describe so we will see if it works or not. I am working on something grander that is taking up my KSP time though..

 Great job getting a working example made!
