Robot 3 • Missile Turret

Stand Motor Step 0

Connect the axle joiner to the motor and then insert
the axle into the axle joiner. Make sure the wire of
the wire connector brick sits in the groove at the top
of the motor—you don’t want the wire to get
caught up in the gears.

Stand Motor Step 1

Slide the worm gear
and then the 1x4
TECHNIC brick onto
the axle. Make sure
the axle goes
through the center
hole of the brick.

Designing & Planning…
Gear Size Matters…

This entire assembly that you are building could be made smaller. Instead of using a
worm gear, attach the motor directly to the gear you are trying to turn. (However,
frequently, the motor will not have enough torque for your purposes. In such cases, a
worm gear is an ideal way of increasing a motor’s torque.)
