First you need a VRML editor to create the model (you can use Labview to create it too), and then you can open it and control it by usin the 3d Picture Control of the Graphis and Sound palette.

Here you got a small help to start http://zone.ni.com/devzone/cda/tut/p/id/3170

If you already have your robot model opened in a 3dPicture...then you can use the Set Translation and Translate Object vis on the transformations palette to move the different parts of the model.

build a 2 dof robot with VRML.I want to rotate any link of robot when I change its
angle(example : when I change angle of link 2,I want to rotate link 2 but I don't want

 to rotate link 1)I load my example with Load VRML.vi.I use object of 

Transformation.Rotate that it need a Axis and a Angle for rotation. When I set it,

whole robot rotate but I want to rotate link 2 without rotation link 1.
I attached a schematic from my robot.

Hi all,

 

I also had some problem with vrml loading. You have to check if solidworks saves the file in "vrml 95" then it should work.

 

For translation and translation, you have to take into account that if you apply a translation or a rotation to an object, all the sons objects will also do the transformation/rotation.

 

So for your robot, the first segment must be the "main object" and then the second segment can be the son object. With this strategy you just have to apply 2 rotations to make your robot move.

 

(Analyze the solar system VI in the examples, the moon is a son of the earth, that makes the geometrical transformation much easier)

 

Regards

 

Marc
