If you could find this information , write half page about the materials used to build this robotic arm.
another 2 pages about the processing (shape formation)of it. Examples for processing -to make my point clear but not limited to it-

casting and molding. Please choose the best process that fits every part and justify it.Please explain all manufacturing processes and

methods used for shape formation.
If you could not find needed information about the materials used to build the arm and processes used to manufacture the arm , please to

make a good estimation of that.

This YouTube video shows you the arm which may help you to have better estimation

For another half of a page: verify and validate the final product

for another page: compare between this robot arm and another robot arm. Choose one you can find information about it online
