Self moving/motivated RBD objects?

[Martin B]

Hi there,

I'm trying to make a load of vegtables roll along the ground (might have to go up inclines, around bends etc), but in a purposeful motivated way, think zombie vegetables. I've been playing with various RBD sims and am getting some ok movement but there's a large variety of odd shaped veg, some skid and some end up stalling. Also working in some slighly strange movements like a cucumber but its moving end over end instead of rolling.

So I was thinking of trying to set something up along the lines of one of those balls you get for pets that has a little motor inside it https://www.youtube.com/watch?v=gBGwoxU8yEs

But I wasn't sure how to approach it... In my head it would be animating the centre of mass to be lower and in front of the direction I want them to travel. Or is there a simpler way to cheat it?

Any pointers would be greatly appreaciated, I'm comfortable in Houdini but dynamics isn't my forte.

Cheers

Martin
