I would like to animate the chair with 1 dummy and just have the casters follow and rotate when the body of the chair rotates , instead of keying the casters individually.  Is this possible with constraints?

Any help would be great.

Thanks

This realtime spring script might be useful.

Constraints for the most part but you are going to have to set up one object that will lag behind the direction that the chair is moving. Use a script controller and create a variable that is looking at the position of the chair. The expression will just be that variable then set the tick offset to a negative value. Now you can use lookat constraints on the wheels to look at the object that is lagging behind and turn on keep offset so they don’t all converge on the one point.
