The original parts are a machined plastic. It is the weight reduction I am interested in. The product picked and placed with the robots are fairly lightweight, and the end effector actually weighs more than the product.
Description of problem: I have 12 very high speed pick and place industrial robots, with lightweight carbon fiber arms, but relatively heavy machined plastic end effectors. I have a lot of issues with failing u-joints, etc. because apparently the payload (end effector plus product) is too heavy...
