EXPERIMENT
8
Arms wide open
Here’s how
1. Attach the four rods to the gyrobot’s head as
shown.
2. Hang the head assembly in the frame similar
to how it was hung in the previous
experiment.
3. Turn the gyroscope on and wait for it to reach
its top speed. What do you observe about the
position of the head? Now rotate the two
arms inward toward each other as shown.
How does this affect the position of the head?
The arms affect the center of gravity of
the head assembly. When the arms are
extended away from the pivot point, the
center of gravity of the head assembly
also shifts, and this pulls the model
downward on this side. The gyroscope is
not quite strong enough to compensate.

Do you have your own ideas
for experiments you can
try with the gyrobot? Now
that you know how to safely
operate it, try out your own
experiments.
Keep going!
