We wanted to build a giraffe and
we wanted the head to move up and down. |
|
It was a real challenge to get the
head working properly. We tried to use gears, but we couldn't get
them to work. So we used a pulley system. |
 The
Neck Problem
see our movie |
The first time we tested our design,
there was too much power going into the motor that controlled the
neck. When it ran the neck and head fell off the giraffe. |
