3.3 Attaching the Theta Drive Shaft
The information in this section only applies to robots with a 4 axis option.
The theta drive shaft consists of a sliding cylinder and ball joints at the ends. The upper U-
joint connects to the robot base. The lower U-joint connects to the platform.
IMPORTANT:
The drive shaft is not symmetrical. There is a top and a bottom.
Installing the drive shaft upside-down will degrade system performance. A
“Top” label is included on the drive shaft.
