ROLL
Roll is one of three types of motion that a robotic end effector can make.
It is a rotational form of motion, unlike pitch and yaw, which are back-
and-forth (or up-and-down) movements.
Extend your arm out straight, and point at something with your index
finger. Twist your wrist. Your index finger keeps pointing in the same
direction, but it rotates along with your wrist. If your index finger were the
head of a screwdriver, it would be able to turn a screw. This is an example
of roll. Compare PITCH and YAW.
