WHAT’S HAPPENING
When the rotor disk rotates clockwise, the
body rotates clockwise. Then when the rotor
disk rotates counterclockwise, the body also
rotates counterclockwise. When the disk
spins, the model is experiencing what is
called a torque. Torque is a force that causes
something to rotate. When you turn a bolt
using a wrench, you are applying a torque.
This is why the model spins in the direction
that the disk is spinning.
So, how is the factory robot able to use a
gyroscope to find its arm’s position? It
does this by measuring the amount of
torque that a gyroscope inside the arm
experiences when it turns and using the
torque measurements to calculate the
distance and direction the arm moved.

Assemble the model.

Pull the rip cord so that the rotor disk
in the gyroscope turns clockwise. Does
the rest of the model rotate clockwise or
counterclockwise? Repeat this with the
wheel turning counterclockwise.
