Setting the Power Rail collectors
4
Loosen the two captive thumbscrews in the collector door so that the door opens (see
Figure 19
).
5
Set the X-preload tensioner by pushing the retaining pin up into a hole on the drive gear (see
Figure 21
). Using two hands, use one thumb to rotate the gear that sits on top of the spring toward the back of
the robot while at the same time using the other hand to pull the drive shaft toward the front of the robot
until a hole becomes available in the bottom of the gear into which to push the pin. Push the pin upward
so that it slides into the hole. (You will pull the pin back down later to load the tension spring.)
On the video, this step can be found from 2:49 to 3:20
CAUTION
VERY IMPORTANT! Loading the tension spring properly ensures
proper robot position and operation. Make sure that the retaining pin
is in the hole before proceeding. If the pin becomes disengaged
before the robot is fully installed (i.e.,drops down and gears engage
with the gear racks), you must remove the robot from the library and
put the pin back in again. If you bump the robot or set it down too
hard, the pin may disengage.
