26 .Basic Robot Motions and DOF of industrial robots 

27 . Arm and Body Motions •Vertical Traverse: •up-and-down motions of the arm, •caused by pivoting the entire arm about a horizontal axis or moving the arm along a vertical slide •Radial Traverse: •extension and retraction of the arm (in-and-out movement) •Rotational Traverse: •rotation about the vertical axis (right or left swivel of the robot arm) 

28 . Wrist Motions 

29 . Basic Motions Rotational vertical traverse traverse Wrist bend radial traverse Wrist Swivel Wrist yaw
