Note: Remounting the wheels (and, if using the ActivityBot,
the wheel encoders) “axle-forward” moves the axle closer to
the front of the chassis. This helps prevent your robot from
tipping forward when it picks up objects.
•
Remove the wheels and un-mount the servos,
keeping the screws and nuts. Turn the servos over
and re-position them so their axles are closer to the
front of the chassis.
•
If using the ActivityBot, unscrew and detach each
encoder sensor from its bracket. Turn around each
bracket and re-attach each encoder sensor so the
lenses are repositioned over the servo axles, see
Fig #16A
on the next page.
•
Re-mount the servos with original screws and nuts.
•
Attach the hinge mount to the front of the chassis
with 4-40 x ¼" screws and nuts as shown in
Fig #14
and
Fig #15.
•
Double check your work against
Fig #16A/B.
