I’m trying to model a robot-arm (i.e. a thing with hinges). I want to constrain the joints to rotate about just one axis. Can anyone advise me on how to set this up in blender using some combination of constraints / parenting.
I’ve seen all the tutorial on mechanical modelling but I’m still stuck…
How-ever I try to set this up, I can (and therefor do, intentionally or not) always rotate the joints in an un-physical way (i.e. not just about the specified rotation axis for that joint/hinge). The Track-To and Lock-Track constraints seem to define the object orientation absolutely and do not allow any freedom of rotation about the joint-axis.
Any help would be much appreciated.
