Bumper Step 4

The round plates form a
mechanical stop that holds
the feelers in place. The
plates are large enough to
prevent the feelers from
tangling, yet small enough
not to impede the feeler’s
movement.
The half-length pin
holds the mechanical
stop in place.

Bricks & Chips…

Did You Know?
The short shaft on the half-length pin is the same size
as the studs on top of LEGO bricks and plates. It can be
used to put studs on the side of a TECHNIC beam.

Bumper Step 5

The #3 axles and perpendicular axle
connectors make a hinge that allows
the feelers to pivot freely.
