Robot 9 • The SpinnerBot

Arm Drive Step 7

Place the 1x6 plate behind
the motor to prevent it from
sliding out of its holder.

Arm Drive Step 8 Secure the black 1x7 TECHNIC half-
beam to the two three-quarter
length pins. When you assemble
the entire robot, this will line up
with two more three-quarter
length pins, providing a
secure reinforcement to the
model.

Slide the Arm Drive sub-assembly
off to the side; you’ll need it in
Final Step 16.
