Robot 1 • The Bug

Left Wheel Step 2 Left Wheel Step 3

For the left
wheel, the
yellow plate is
on the bottom
and to the left
of the gray 2x4
TECHNIC plate.

Left Wheel Step 4
Locate the second motor mount
sub-assembly and slide it onto the
axle. The two stop bushings
help hold the wheel assembly
and the motor mount together.
This is the weakest
connection in the Bug’s
design. After extended use,
the wheel assembly and
motor mount may begin to
separate. If this occurs,
correct the separation by
snapping the bottom
plates back in place and
sliding the bushings
down the axle until they
contact the upper plate.
