I thought this would be a cool idea to try and once I get time, I want to try simulate one of my robots using this sort of method.

So, the secret is: You have to increase the lateral traction of the caster wheels (side wheels) to 3000 or so and link the parent wheel to the car using a hinge joint with a motor.

Here's an example I dug up from the depths of my HDD. This is pretty old actually. Was rendered in Rhino3D

that is pretty sweet.

so you are using 3drad for robotic simulations? if so is it pretty reliable and realistic? I have been trying to find a way to test out some designs before actually building and if 3drad could be used that would be awesome.

Sweet! It simulates perfectly.. Now, who want's to program the mixer?

Heres a compiled version for all of you who don't have the latest 3DRad.

When I try to open the 3drar I get an error saying cant find file sky5x 02

PsychoWeasel9 · « **Reply #13 on:** February 06, 2010, 03:27:34 PM »

you'll need to get skyy5x from 3drad.info

Rush3Fan · « **Reply #14 on:** February 06, 2010, 08:29:41 PM »

Oh, sorry. I thought I had all defult objects. I guess not.

Still, It is definately worth checking out those skyboxes. They are awesome!
