I don't understand why the summary would leave out the witness statements.
Witnesses said the chaos unfolded at the busy office, which had a line out the door. Jalen Eddings told WHAS-TV that he had gone to the office but went back to his car to wait out the long line when the shooting unfolded nearby. He said two masked men shot the man multiple times, including as he lay on the ground, before they ran off. He said he didn’t see them fire at the women.
An assembly line robot (like welding or material handling, I've worked with ABB, Fanuc, Motoman, Panasonic) are still called robot "arms" with the end portion often called the "wrist" so there is a degree of anthropomorphizing even if it's not the whole body. And they do resemble an arm, however with 6 axis motion the motion is more like from your hips to your wrist than shoulder to wrist.
