Spencer's tenure in industrial robot design is impressive:
I agree! Spencer is not only a master roboticist, he has 20+ years in sales and marketing! He ran a 4 store chain of stereo shops PROFITABLY for over 5 years is what I read. Then he got an MBA from one of the top 100 EMBA programs in the world!
He was instrumental in the development of the world's FIRST two legged walking robot, CURBi in 1987.
Spencer knows a lot about robot arm design. Perhaps Ifoo not so much? You could call and ask them why if you want.
