Calibration idea #1
Comments
That is really good to hear! I found that assuming that the arm lengths were as nominally specified have better results of measurements that iteratively trying to solve multiple simultaneous equations for X,y,z position given length and angle of each arm and sensor.
Let me know how it works out! I will post the solution.
One concern I have with using several video cameras is that if you have that equipment then you might be able to use it directly to determine the 3D point cloud of the surfaces!

Very cool project. I might be able to help with the calibration. My M.E. masters project many years ago involved brute force calculation the position of joints in a robotic arm from the data of two video cameras. I think the approach would work here. When I get a chance, I'll take a deeper look to see if I can make a unit for testing.
