Best SketchyPhysics Setup?

Is this the best sketchyphysics setup?

I've been trolling the web far and wide to learn more about sketchyphysics and haven't seen anything like this but it seems amazing - it has automated walk functions so you press forward on the joystick and the machine places its own feet.....and the way the ruby is written seems totally contrary to any other models or the recommendations in the SPwiki - it doesn't use Wacov's infamous toggle script when it toggles between functionality.

Have a play with it yourself:

If anyone can tell me anything about this cleverly designed SP rig then I would like to know more - I have been trying to reverse engineer some of the functionality out of the script but its not that intuitive to an SP noob like me. I would love to emulate the servos on the arms that stay where they are placed for example. I am also unable to make it crash wheras my models with similar functions crash regularly. Here's the ruby out of it:

Amazing model!
Maybe here the creator of ScketchyPhysics will can help you

You had a play with it Pilou?

Did you notice all of the functionality? - the toggle between legs and working arms? The automated walk feature? The way the arm servos stay where you but them rather than springing back?

I love it

Not yet
In the past i had play with this

Thats cool Pilou - however, it doesn't have the scripting knowledge that is required to make something walk. Lifting and placing legs is a whole lot more complicated than turning wheels - but I agree, that is a beautiful warthog.

Boy, the sketchyphysics part of the forum sure is quiet compared to what it used to be - is there some other physics simulation software that I'm not aware of?

I would love to get sketchyphysics back in the limelight - its such a fantastic bit of kit

Managed to reverse engineer some of the stuff on this amazing setup - see this thread: http://forums.sketchucation.com/viewtopic.php?f=61&t=44399

Maybe it is best sp setup, but pieces (legs, arms ...) dont colide as they look like. You can see my models similar to this on my site: http://forsa07.wix.com/dl-design#!design/cc9
