Hi, I am trying to recreate a gimbal such that the inner rung always points to earth center(for our purposes -Y) regardless the position of the main chassis.
It is a three ring gimbal with the chassis being the third "outer" ring. Ring 2 (middle) is X rot, ring 3 (inner) is Z rot. Ring 3 Y axis should always be pointing down regardless orient of chassis. Tried locking down the rot limits and then using direction constrains but the direction constrains seem to ignore the rot limits in effect disabling them. Has anyone ever done this? Having a lot of difficulty with this. -- Joey Ponthieux LaRC Information Technology Enhanced Services (LITES) MYMIC Technical Services NASA Langley Research Center __________________________________________________ Opinions stated here-in are strictly those of the author and do not represent the opinions of NASA or any other party.
