Ok, lets see if I can explain how I want the movements to be.
So, the robot isnÂ´t yet attached but in this image I have rotated bone #6 and you can see how the bones have turned, thatÂ´s how I want the robot to work aswell.
I numbered the bones and parts of the robot that belong together. Bone #3 is just there to keep #9 from rotating and so that #7 and #4 stays moves together, IÂ´m not even sure if #3 is necessary. I watched a tutorial on rigging a piston and used what I saw there. #9 is to control the telescopic part #1 if it needs to be extended. I didnÂ´t want to extend it always. The setup of bone #1, #2 and #8 is according to the tutorial I watched.
#5 should not rotate but #4 must rotate from the connection point. #5 and #3 are the same length as is #4 and #7.
Did I make it any clearer?
Should I apply the rotation, scale and location before making the constraints?
As you probably can tell IÂ´m a beginner in rigging but I try my best to learn.
Oh, yes, itÂ´s this robot:
All the best
