Robot 9 • The SpinnerBot

Final Step 18 Attach the Spinner Arms sub-assembly. Slide the loose end of the
Arm Pivot into the right side of the robot. The end should be
secured using the 5-length gray half-beam from the Lower Arm
Drive. Firmly press the beam at the other end of
the Arm Pivot onto the Drive Mechanism. The 5-
length gray half-beam at this
end of the

Arm Pivot
will align with and clip onto
a three-quarter length pin
attached to the side of the
Drive Mechanism.

Final Step 19

Attach the
wheels and tires. Take a
moment to rotate each
wheel. The left wheel should
freely spin backward while the right
wheel freely spins forward. If the wheels do
not move freely, take a moment to adjust any
parts that might be in contact with them.
