I am facing issue while doing kinematics for X- Gun. In one case i am getting J5 as a main joint and in other case j1. How is it possible.? Is there something i am missing?
I can get exact mechanism with RPRR linkage mechanism and i can get j1 as the main joint for gun opening but the opening value which is i am getting is -70mm max. but as per above mentioned method i am getting value for same j1 as -140mm. So i am not able to understand why this difference is occuring?
