The problem to besolvedis that you need both forward and inverse kinematics. Forward is where you have a set of joint angles and you want to know the location and orientation of the end of the arm.This is easy for most people who still remember trigonometry from high school. If not go to

Hi chris, i would like ask you something, based on you said , I need to figure out how my elbow angle is moved in function to my base angle, and after this i will need to add this function to my kinematics file, in that case i would be using the DH parameters so, i should modificate genserkins,

I think what you have is a circular link.That means a parallelogram type geometry. I have a robot arm like this too but mine is MUCH smaller and lower cost. Mine is nearly identical to this arm on Amazon. .amazon.com/Blesiya-Professional-Aluminum-Mechanical-Educational
